Constant Voltage/Constant Current Crossover Characteristics

Background	The unit will switch automatically between constant voltage and constant current according to changes in the load.
CV mode	When the load current is less than the current setting, the unit operates in constant voltage mode, changing the current level according to the load but maintaining the set voltage level until the current reaches the set current level. The status indicator will show CV on the LCD when in CV mode.
Constant Current Mode	When the output current reaches the set current level, the unit switches operation to constant current mode. The status indicator will show CC on the LCD display. In CC mode, the current level is maintained and the voltage level is limited to less than the set voltage level to limit the output power from an overload. When the current drops below the set current level, the unit will revert back to CV mode.

LimMode

Current limiting mode. There are 4 settings for the current limiting mode: Limit, Trip, LimitRelay and Trip Relay.

The Limit settings will limit the current. When the current reaches the setting value, the current remains constant, as in CC mode.

The Trip setting will turn the output off when the current limit has been reached.

The Limit Relay setting will assert the relay output control interface low when the output current reaches the limit setting. Otherwise, the relay output interface will be asserted high.

The Trip Relay setting will assert the relay output control interface low when the output current limit is tripped. Otherwise, the relay output interface will be asserted high.

See page 59 for details on the Limit Relay and Trip Relay settings.

	RelayControl	The relay control settings have 2 configurations: Zero/One.
		The Zero setting means that the output from the Relay control interface OUT port is low and the external relays will energize.
		The One setting is just the opposite of the Zero setting.
		The user sets the initial state. When the state of the relay control signal changes, the actual state of the relay is displayed.
	Resistance	See page 59 for further details.

Pulse Current Measurement

Description

Changes in the load current allow us to measure the pulse current.

There are three ways that pulse current can be measured:

1. Measuring the peak current over a single cycle (High Measurement).
2. Measuring the trough current over a single cycle (Low Measurement).
3. Measuring the average current over a single cycle (Average Measurement).

High Low Average

The high and average measurements are triggered by the rising edge of the pulse current are performed for the time specified for the measurement.

Low measurement is triggered by the falling edge of the pulse current.

Note: Pulse current measurement is only valid up to 5A or 10A (CH1) and 1.5A or 3.0A (CH2).

Parameter Description

IntTime

- Integration Time.

- The integration measurement time can be set to automatic or to one of the manual settings (High Time, Low Time and Aver Time).

- When the integration measurement time is set to

automatic mode, the system will measure the peaks and troughs of the pulse current and will automatically set an appropriate integration time. The average integration time is the time of all the accumulated peaks and troughs. After the setting the integration time to automatic, the setting will apply to all subsequent pulse measurements, unless the automatic integration mode is applied again or the integration time is manually set. The automatic Integration time can automatically detect pulses in the 80us to 833ms range.

- The manual time range setting is 33us to 833333us. The default units are in microseconds (us).

IntTime setting automatically becomes 33.3 microseconds (us) in mode (Pulse current digitization)

For details, please refer to page 109

TrigDelay

• Trigger Delay
• When a pulse is detected, there will be a 25us code execution delay time. The trigger delay settings are used to filter out the current overshoot. Measurement will begin from after the trigger delay time. The trigger delay setting range is: 0\~0.10000s, with a resolution of 0.00001s. The setting units are in seconds.

	Note	The setting range for TrigDelay is 0~5 sec.(s)in mode (Pulse current digitization) For details, please refer to page 112
	AverRead	·Average Reading Count: Reads back the average number of displayed values.·This parameter is only applicable for pulse current measurement. The average number range can set from 1 ~ 100 with a resolution of 1.
	Note	The setting range for AverRead is 1 ~ 5000 with a resolution of 1 (Pulse current digitization). For details, please refer to page 108
	Trig Level	·Trigger Level.·To avoid false pulse measurements, the trigger level can be set close to the current amplitude. All noise and transient currents that are below the trigger level will be ignored. The trigger level has a setting range of 0~5A (CH1), 0~1.5A or 0~3.0A (CH2) with a resolution of 5mA. The setting unit for the trigger level is in amps (A). This setting is only valid for pulse measurements.

Long integration

Description

The long current integration measurement function measures the mean (average) current over a single or multiple current pulses. The long integration time period must be a full period or integer multiples of a complete period of the measured pulse current. The Long integration measurement calculates the whole integration time as an integer number of integration cycles. An integration cycle is the line cycle period plus the data processing time.

For example, if the line frequency is 60Hz, then a single integration cycle is 16.7mS, if the frequency is 50Hz, then a single integration cycle is must be 20mS. Long integration is one of the methods to extend A/D circuits to exceed beyond their maximum integration time. The A /D conversion circuits can measure a pulse of up to 833 ms. Long integration measurement extends the A/D integration time to achieve a longer pulse measurement. This can extend the measurement time for long integration to a maximum of 60S.

Note: When this feature is used, the current range is set to 5A (CH1 with PPH-1503D/1506D), 10.0A (CH1 with PPH-1510D).1.5A (CH2 with PPH-1503D), 3.0A (CH2 with PPH-1506D/1510D).

Parameter

Description

IntTime

- Integration time

- The integration time can be set manually or automatically by the operator. For manual settings, the integration time can be set to a maximum of 60 seconds. For a line frequency of 60Hz the minimum integration time is 850ms with a step resolution of 16.7mS. For a line frequency of 50Hz, the minimum integration time is 840ms with a step resolution of 20ms.

- When the integration time is set to Auto Time, the system will automatically measure the time between two adjacent rising edges and an appropriate integration time is set for the peak and trough. If there are more than two pulses, the integration time must be set manually.

TrigEdge

- Trigger edge

- Pulse edges are used to trigger long integration measurement.

Regardless of whether a rising or falling edge is used as a trigger, a pulse must first be detected before measurement can start.

Measurement can also start without an edge trigger. When TrigOnNeither is selected, measurement starts as soon as the output is turned on.

Trig Level

- Trigger level.

- When the rising or falling edge trigger is selected for long integration current measurement, a pulse must first be detected. The trigger level refers to minimum pulse level required for a pulse to be detected. For example if the trigger level is set to 2A, pulses that are ≤2A will be detected. Pulses <2A will be ignored. The trigger level range is 0\~5A (CH1), 0\~1.5A or 0\~3.0A (CH2). This setting only applies to long current integration measurements.

Timeout

- Pulse timeout

- When long integration measurement is selected and the unit doesn't detect a pulse after a certain amount of time (pulse timeout time), the "No Pulse" message will be displayed on the LCD. This function is only applicable if rising or falling edge is selected as the edge trigger; the Trig OnNeither trigger setting has no pulse timeout. The pulse timeout has a range of 1\~63 seconds.

Battery simulation function

Function

Description

The function can be seen as being equivalent to power source U in series with resistor R. The equivalent circuit model diagram is shown below:

R U Uo

The unit has an internal series resistor that can set the resistance of the circuit to simulate the output voltage of a battery.

Output voltage

When CH1 is outputting current, the output voltage will decrease when the output current increases.

When CH1 is used as a sink, the output voltage will increase with an increase in output current.

Setting the internal resistance

The internal resistance setting range is 0.000 to 1.000 ohms. For detailed operation, please refer to page 40.

Current Sink Function

Function

Description

When the test circuit is an active circuit, and the manifested voltage in the test circuit is greater than the output voltage of the power supply, the power supply will automatically disipate current from the external power supply. When this function is in the normal operating state, the power supply outputs the setting voltage, which is equivalent to a constant voltage load rather than constant current load.

The current disipation from the power supply output flows from the positive terminal out to the negative terminal. The amount of current sunk is not controlled from the power supply.

Connection

Connect the positive terminal of the external power supply to the positive terminal on the high-speed power supply. Connect the negative terminal of the external power supply to the negative terminal on the high-speed power supply.

PPH-1503D + 3.0V - I sink R + 4.2V - V

Conditions

To protect the high-speed power supply when operating as a current sink, the following two conditions must be met:

1. Ensure that the voltage of the external power supply is greater than the output of the high-speed power supply voltage by 0.3V\~2.5V. The voltage difference depends on the high-speed power supply voltage output and the load conditions.
2. To ensure that the power supply output voltage is within certain range, the current draw must be less than the limit value. See the formula in the Table below for the details.

CH1: To ensure that the high-speed power supply output voltage is within the range of 0\~4V, the current draw cannot exceed 3.5A. For output voltages between 4V\~15V, the current draw must be reduced by 0.25A for each 1V increase. See the formula in the table below for the details.

High-speed Power Supply Output Voltage	Maximum Dissipation Current
0~4V	3.5A
4V~15V	3.5A-(0.25A/V)*(Vset-4V)

CH2: To ensure that the high-speed power supply output voltage is within the range of 0\~5V, the current draw cannot exceed 2A(or 3A). For output voltages between 5V\~15V, the current draw must be reduced by 0.1A(or 0.25A) for each 1V increase. See the formula in the table below for the details.

High-speed Power Supply Output Voltage		Maximum Dissipation Current
0~5V	1503D	2.0A
	1506D/1510D	3.0A
5V~12V	PPH-1503D	2.0A-(0.1A/V)*(Vset-5V)
	1506D/1510D	3.0A-(0.25A/V)*(Vset-5V)

External Relay Control

Function

Description

When the Relay control feature is turned on, it is synced to the current limit of the power supply. The external relay control is divided into two different types, a limit relay and a trip relay.

The limit relay is used in conjunction with CC mode. When the constant current setting value is reached, the relay control signal will go high and will return back to the low level when the current level goes back below the constant current setting.

The trigger relay is used in conjunction with CC mode. When the constant current setting value is reached, the relay control signal will go high and the output is disabled. When the output goes back on and the current is less than the current setting value, the relay control signal will back to the low level.

Rear Panel

Control Interface

The rear panel control interface has five terminals, +5V, IN (The state of the Trip or Trip Relay output is used as the signal input), OUT (CH1 & CH2 controls signal output) and GND (connected to the chassis ground or earth ground), respectively.

Wiring Method

A thin screwdriver or similar tool will need to be inserted into the release mechanism (highlighted in orange in the figure above) to open the terminals. Insert an exposed wire into the terminal and release the mechanism to lock the wire into place.

Command Syntax

The commands that are used with the PPH-1503D/1506D/1510D meet IEEE488.2 and SCPI standards.

SCPI Commands Overview SCPI

Command Format

SCPI is an ASCII based command language designed for test and measurement instruments. SCPI commands uses a hierarchical structure (tree system), and is divided into different subsystems. Each subsystem is defined by a different root keyword. Each command consists of a root keyword and one or more hierarchical key words separated by a colon “:” and followed by a parameter. There is always a space between the keywords and the parameters. Any commands followed by a question mark (?) are queries.

For Example:

:SYSTem:BEEPer:STATE {0|1|OFF|ON}

:SYSTem:BEEPer:STATe?

SYSTem is the root level keyword and BEEPer and STATe are the secondary and tertiary level keywords. All levels have a “:” separating each keyword. Parameters are enclosed in “{}”.

The commands SYSTem:BEEPer:STATe has {0 | 1 | OFF | ON} as parameters. The parameters are separated with a space.

SYSTem:BEEPer:STATe? indicates that the command is a query. In addition some commands have multiple parameters that are usually separated by a comma “,”.

For example: :STATUS:QUEue:ENABLE (-110:-222, -220).

Symbol Description

SCPI commands have the following conventional symbols. These symbols are not commands but are used to describe the command parameters.

1. Curly Brackets {}

Curly Bracket enclose command string parameters, for example: {OFF | ON}

2. Vertical Bars |

Vertical bars are used to separate one or more optional parameters. Only one command can be selected. With the following two parameters, {ON | OFF} only ON or OFF can be selected.

3. Square Brackets [ ]

The contents inside square brackets represent keywords or parameters that can be omitted when executing a command. For example: For the commands :OUTPUT[:STATe] {ON | OFF}, [STATe] can be omitted.

4. Angle Brackets < >

The parameters in angle brackets must be substituted with a valid parameter. For example: For the command :DISPLAY:CONTrast , must be use a numerical value instead such as, :DISPLAY:CONTrast 1

Parameter Types

The commands have a number of different parameter categories. How the parameters are set depend on the parameter categories.

1. Boolean

Commands parameter that have to states "OFF" and "ON", for example, DISPLAY:FOCUs {ON | OFF}. "ON" will turn on the focus display function, while "OFF" will turn it off.

2. Consecutive Integers

Parameters that use consecutive integers, for example: For the command :DISPLAY:CONTrast , is an integer value with a range of 1\~3.

3. Continuous Real Number

Parameter that must be a continuous real number can have any value within the effective range and accuracy. For example: The command CURRENT { | MINimum | MAXimum}, is used to set the current value for the current operating channel.

can be any value within the setting range of the current channel.

4. Discrete

For discrete parameters, only those values that are listed can be used. For example: The *RCL {0 | 1 | 2 | 3 | 4 | 5} command can only use 0, 1, 2, 3, 4, 5.

5. ASCII Strings

ASCII string parameters must use a combination of ASCII characters in a string. For example: For the command: MODE , must be an ASCII string.

Command Abbreviations

The syntax for SCPI commands contains a combination of upper and lower case letters. The upper case letters in a command represent the short form of that command.

Commands are not case sensitive and can be used in both upper and lower case. Note, however, to use the short form of the command, only the capital letter part of the command can be used (no other abbreviation can be used). For example:

:MEASure:CURRENT?

Can be abbreviated to:

:MEAS:CURR

Command Terminators

When sending a command to the function generator, the command must be terminated with a character. The IEEE-4888 EOI can also be used as a character. A command can also be terminated using a carriage return + character. The command path will always be reset back to the root level after a command has been terminated.

Return values are terminated with 0x0A.

SCPI Status Registers SCPI

The SCPI instrument configuration is controlled by the status registers. The Status system records various instrument conditions into three main register groups: The status byte register, the standard event register group and the questionable data register group. The status byte register records a high-level summary of the other register groups. The following diagram is the SCPI Status System diagram.

Event Registers

The operation, measurement and questionable status register groups all have event registers. The event registers are read only registers that reflect the status of the unit. Individual bits in the event registers are latched (set) when a corresponding event occurs and will remain latched even if the corresponding event changes, as long as the event bit is still set. The register query (*ESR) or the command (*CLS) will automatically clear any set bits in the event registers. The reset command (*RST) will not clear the bits in the event register. Queries for the event registers will return a binary-weighted decimal value that represents the state of all the bits in an event register.

Enable Registers

The enable registers define which bits in the corresponding event register can be latched (set). The enable register can be read and written to. Any queries for the enable register will not clear the value in the register. The *CLS command will not clear the enable register, but will clear the events in the event register. To allow the individual bits in the event registers to be set, the corresponding bits in the enable registers must be set, where each bit is represented by a binary number.

The status byte register reports the status of the other status registers. The message available bit (bit 4), will indicate when there is a message in the output buffer. Clearing an event register will clear the corresponding bit in the status byte condition register. Reading all the data in the output buffer will clear the message available bit. To set the enable register mask for the status byte register and to generate an SRQ (service request) you must use the *SRE command to write the appropriate decimal value to the register.

Bit Definition for the Status Byte Register

Bit number	Decimal value	Definition
0 Not used	1	Not used, returns “0”
1 Not used	2	Not used, returns “0”
2 Error Queue	4	Indicates that one or more errors are stored in the error queue.
3 Questionable Summary bit	8	One or more bits are set in the questionable data register (for enabled events).
4 Message Available bit	16	Indicates that a message is available in the output queue.
5 Standard Event Summary bit.	32	Indicates that one or more bits are set in the standard event register. (For enabled events).
6 Master Summary bit	64	Indicates that a summary bit is set in the status byte register. (for enabled summary bits)
7 Unused	128	Not used, returns “0”

The status byte condition register is cleared when one of the following occurs:

• *CLS command is used to clear the status byte register.
• You read the event register from another register group (only clear the corresponding bit in the condition register)

The status byte enable register is cleared when the following occurs:

- When the *SRE 0 is command is executed.

Use the *STB? query to read the status byte register.

The *STB? query will return the contents of the status byte register as long as the bit 6 (MSS) has been cleared.

Using the *OPC? query to place a signal in the output buffer.

In general it is best to use the Operation Complete Bit (bit 0) in the standard event register to check to see if an operation/command has

completed. After executing the *OPC command, the OPC bit will be set to 1. If a command or query is placed in the output buffer immediately before the *OPC command is sent, the Operation Complete Bit can be used to determine when the information can be used. However if too many commands/queries are executed prior to the execution of the *OPC command, the output buffer could become saturated and the unit will stop taking readings.

Standard Event Register

The Standard Event Register reports the following types or events: Power on has been detected, command syntax errors, command execution errors, self test and execution errors, query errors or if the *OPC command is executed. Any one or more of these events will set the standard event summary bit in the status byte register. To set a mask for the enable register, a binary-weighted decimal number must be written using the *ESE command.

Bit Definition for the Standard Event Register

Bit number	Decimal value	Definition
0 Operation Complete Bit	1	The *OPC command will set this bit when all overlapping operations have completed (including the *OPC command itself).
1 Not used	2	Not used, returns 0.
2 Query Error	4	The instrument tried to read the error queue when the queue was empty or the queue was read before a new command was given or the input/output buffers are full.
3 Device Error	8	A self-test, calibration or other device-specific error.
4 Execution Error	16	An execution error.
5 Command Error	32	A command syntax error.
6 Not used	64	Not used, return 0.
7 Power On	128	This bit is set if the power supply has been reset from the last time you read the event register.

The following will clear the standard event register:

•The *CLS command is executed.

•The *ESR? command is used to query the event register.

The following will clear the standard event enable register.

•The *ESE command is executed.

Status Byte Register Commands

Command	*SRE
Function	Service request enable register (SRER) command that writes a binary weighed value which determines which events in the status byte register are enabled.
Function	Allowed Decimal vales: 0~255 values
Example	*SRE 7Returns the SRER setting (0000 0111)
Command	*SRE?
Function	Queries the status byte enable register. This command returns a binary-weighted decimal number that indicates which bits are set in the status byte register. The range is from 0~255.
Example	*SRE?Returns “7”, which are the contents of the service request enable register.
Function	*STB?
Function	Query the status byte register. This is the same as performing a serial poll, however the master summary bit (MSS, bit 6) will not be cleared by the *STB command. The return value range is from 0 to 255.
Example	*STB?Returns 81 if the status byte register is set to 0101 0001.

Standard Event Register Commands

Command	*ESE
Function	Sets the standard event enable register. The allowable value range is 0~255.
Example	*ESE 65Sets the ESER as 0100 0001.
Command	*ESE?
Function	Queries the standard event enable register. It returns are binary-weighted decimal value representing all the enabled bits in the standard event register.
Example	*ESE?Returns 65, as the ESER is set as 0100 0001.
Command	*ESR?
Function	Queries the standard event register. It returns a binary-weighted decimal value in the range of 0~255.
Example	*ESR?It returns 198, as the ESER is set as 0100 0001.

Other Status Register Commands

Command	*CLS
Function	Clears the status byte summary registers and the all event registers.
Example	*CLSClears all the event registers. 涵盖 Standard event registers, Operation event registers, Measurement event registers, Questionable event registers.
Command	*OPC
Function	After all the pending operations are complete, sets the operation complete bit in the standard event status register.
Example	*OPC
Command	*OPC?
Function	Will return “1” to the output queue when all pending operations have been completed.
Example	*OPC?After the last command is executed, will return a “1” to the output queue.

Errors

Error Message

• Errors are stored in a first in-first out (FIFO) order. The first error message that is returned is the first error message that was stored. When an error is read it is also cleared from the queue.
• If there are more than 10 errors produced the last error in the queue is replaced with “Que overflow”. Unless the error queue is cleared, no more errors can be written to the error queue. If there are no errors in the error queue, the instrument will return “No error”.
• To clear the error queue, you can use the :SYSTem:CLEar command or cycle the power. When you read a message from the error queue that message will be cleared from the error queue. Using the *RST command to reset the instrument does not clear the error queue.
• Remote control instructions can be used to clear the error queue. See the instructions listed in the previous chapter for details.
