Chapter 1 Introduction

This chapter gives you an instruction in how to operate RIGOL DM3058/DM3058E digital multimeter correctly using remote control programming in connection with the command symbols and parameters, including:

■ Programming Introduction
■ Symbol Instruction
■ Parameter Types
■ Commands in this Manual

Programming Introduction

The programming system provides an easy way for remote control through corresponding commands, sending and identifying the command word with ASCII strings. Connect a computer with the multimeter through communication interfaces such as USB, GPIB*, LAN* or RS-232 before use.

The operations that you can do through the commands:

• Setup the multimeter.
  ● Make measurements.
  ● Acquire data (instrument working condition or measurement results) from the multimeter.

Note*: The GPIB and LAN interfaces are only supported by DM3058.

Symbol Instruction

1. Colon :

Commands usually begin with a colon (:), which is used to separate the keyword from lower-level keyword, denoting the beginning of an operation to the multimeter.

2. Interrogation?

A query is formed by adding an interrogation (?) at the end of the command. The query command usually contains different data, and both of them usually divided by a space.

3. Braces { }

When several elements separated by a vertical line (|) are enclosed by braces, { }, only one element may be selected. For example, {ON | OFF} indicates that only ON or OFF may be selected, not both.

4. Triangle Brackets < >

The item enclosed in < > should be replaced by an actual value as a parameter.

5. Square brackets [ ]

Some parameters or command keywords are enclosed by square bracket ( [ ] ), indicating that which are optional or could be ignored. If no parameter is set, the system will select a default. For example, [MINimum/MAXimum] can be ignored in command CALCulate:LIMIT:LOWER? [MINimum/MAXimum], while [:EVENT] in command STATus:OPERation[:EVENT]?

Parameter Types

1. Consecutive Integer Parameter

The parameters could be an integer within the valid range. For example, setting the screen brightness from “0\~32” through “:SYSTem:DISPlay:BRIGHT”. Note do not set the parameters with decimal, or else an unexpected exception may occurred.

2. Consecutive Real Number Parameter

Under the precision condition, the parameters could be an arbitrary value within the valid range (usually the default precision takes six effective digits behind the decimal point). For example, in command :CALCulate:REL:OFFSET, the parameters meet the range of the real number in Table 3-2.

3. Discrete Parameters

The parameters can only be the cited value. For example, the parameter of “:MEASure:VOLTage:AC” could only be 0, 1, 2 or 3.

4. Boolean Parameters

The parameters must be ON, OFF, 0 or 1. For example, in command "SYSTem:BEEPer:STATE".

5. ASCII String

The parameter should be a composition of ASCII strings. For example, the parameter of IP address query command “:UTILITY:INTERface:LAN:IP” is a user-defined string.

1. The default measurement rate changes into “Fast” after the command in line 4 was executed, as it is directly corresponding to the resolution, which means you can get a desired rate by setting the precision. For example, sending “conf:volt:dc:auto,max” to change the rate to “slow”.

2. The command in line 7 returns the current measured maximum of DC voltage.

3. The command in line 9 returns the measured times that have been completed.

4. The default measurement rate changes into "Fast" after the command in line 4 was executed, as it is directly corresponding to the resolution, which means you can get a desired rate by setting the precision. For example, sending "conf:volt:dc:auto,max" to change the rate to "slow".

5. The command in line 7 returns the current measured maximum of DC voltage.
6. The command in line 9 returns the measured times that have been completed.

Example 2: Eliminating the Impedance Errors on

Test leads

Purpose: To eliminate the impedance errors on test leads.

Larger deviation may be brought in when you measure the smaller resistance, it is necessary to eliminate the errors induced by impedance of test leads, please perform with following procedures step by step:

Explanations:

1. The operation in line 6 must be done before the next.
2. From the return value in line 18, it is seen that the value is decreased 3 orders of

magnitude comparing with the result in line 9 after the REL operation has been completed, so, test succeed.

2. The command parameter in line 9 is the return value of line 3.

Example 4: dB Measurement

Purpose: Use commands to perform dB measurement.

dB is a common measurement unit, which is frequently used in electrician, wireless, mechanics, oscillatory surge, mechanical power, acoustics and some other fields.

The programming implementations — RIGOL Commands
0 * RST / Reset the instrument / 1 cmdset rigol / Select RIGOL commands / 2 * IDN? / Query the equipment ID and confirm if the multimeter works normally / 3 / Connect the test leads under AC voltage measurement / 4 :function:voltage:AC / Enable the AC voltage measurement / 5 :measure:voltage:AC / Set the measuring range / 6 :calculate:function DB / Enable dB measurement / 7 :calculate:DB:reference / Set the "dB setting" value / 8 :calculate:DB? / Query the measured value / 9 / Return value /

The programming implementations——Agilent Commands
0 * CLS / Clear the instrument state / 1 cmdset agilent / Select Agilent commands / 2 * IDN? / Query the equipment ID and confirm if the multimeter works normally / 3 / Connect the test leads for AC voltage measuring / 4 conf:volt:ac / Enable the AC voltage measurement and set the range / 5 calc:stat on / Enable the math function / 6 calc:func db / Enable the dB measurement/ 7 calc:db:ref / Set the "dB setting" value / 8 calc:db:ref? / Query the measured value / 9 / Return value /

Explanations:

1. When finish the setting of "dB reference value" in line 7, the measured result of dB will be shown on the screen, but the result can not be returned since there is

RIGOL

not corresponding query command.

1. The return value of command in line 8 is "dB reference value", not the dB measured result.
2. Use RIGOL commands if both the dB measurement function and returned value are required.

Example 5: P/ F Testing

Purpose: Use commands to perform a P/F test.

P/F operation prompts for the over range voltage signal according to upper/lower limits, and gives a beep (if the beeper is open).

The programming implementations—RI GOL Commands

0 * RST / Reset the instrument / 1 cmdset rigol / Select RIGOL commands / 2 * IDN? / Query the equipment ID and confirm if the multimeter works normally / 3 / Connect the test leads for DC voltage measurement / 4 :function:voltage:DC / Enable the DC voltage measurement / 5 :measure:voltage:DC / Set the measurement range / 6 :calculate:pf:lower / Set the lower limit to value1/ 7 :calculate:pf:upper / Set the upper limit to value2/ 8 :calculate:function pf / Enable the pf operation / 9 :calculate:pf? / Query the measurement result / 10 / Returned value / 11 :calculate:function none / Exit calculation function /

Explanations:

1. The instrument should be connected under DC voltage mode before sending the command in line 4.
2. Parameters in line 6 and 7 should be: value2 > value1, and both are within the range.
3. The command in line 9 returns "PASS" if the input voltage is within the scope of the upper and lower limits, or returns "FAIL" and a beeper is emitted if it is on.

The programming implementations——Agilent Commands

0 *CLS /* Clear the instrument state */

1 cmdset agilent /** Select Agilent commands */

2 *IDN? /* Query the equipment ID and confirm if the multimeter works normally */

3 /* Connect the test leads for DC voltage measurement */

4 conf:volt:dc /* Set the DC voltage measuring function and the range */

5 calc:stat on /* Enable the math function */

6 calc:lim:low /* Set the lower limit to value1*/

7 calc:lim:upp /* Set the upper limit to value2*/

8 calc:func lim /* Enable the limit operation */

9 calc:stat OFF /* Exit math function */

Explanations:

1. The instrument should be connected under DC voltage mode before sending the command in line 4.
2. Parameters in line 6 and 7 should be: value2 > value1, and both are within the range.
3. Command in line 8 enables limit operation without return value, as no corresponding command is provided in this system. If the parameter input is not within the scope of the upper and lower limits, a beep tone will be emitted (when the beeper is on).
4. Use RIGOL commands if both the P/F measurement function and returned value are required.

Example 6: Reading Hold

"Reading Hold" function can get a stable reading and hold it on the screen even when test lead pens are removed.

The programming implementations—RI GOL Commands
0 RST / Reset the instrument / 1 cmdset rigol / Select RIGOL commands / 2 IDN? / Query the equipment ID and confirm if the multimeter works normally / 3 / Connect the test leads for DC voltage measurement / 4 :function:voltage:DC / Enable the DC voltage measurement / 5 :measure:voltage:DC / Set the measurement range / 6 :trigger:auto:hold on / Enable the reading hold function / 7 :trigger:auto:hold:sensitivity 1 / Set the holding range to "0.1%"/

Explanations:

Command in line 7 permits multiple threshold ranges, for details, refer to Chapter 3.

Example 7: Querying the Status Register

The status register provided enables user to diagnose the current error operation on the basis of its query function, searching the error reason. For the detailed commands, refer to Chapter 2. The commands system of status register is in common use in all RIGOL, Fluke and Agilent, take RIGOL commands for example.

The programming implementations——RI GOL Commands:

0	*RST	/* Reset the instrument */
1	cmdset rigol	/* Select RIGOL commands */
2	*cls	/* Clear the instrument state */
3	status:questionable:enable 24375	/* Set the enable register of the questionable status register */
4	status:operation:enable 1841	/* Set the enable register of the operation status register */
5	* ESE 189	/* Set the enable register of the event status register */
6	* SRE 188	/* Set the enable register of the status byte register */
7	:status:questionable:enable?	/* Query the enable register of the questionable status register */
8	Return 24375
9	:status:operation:enable?	/* Query the enable register of the operation status register */
10	Return 1841
11	* ESE?	/* Query the enable register of the event status register */
12	Return 189
13	* SRE?	/* Query the enable register of the status byte register */
14	Return 188

16	* STB?	/* Query the condition register of the status byte register */
17	Return 192
18	:status:questionable:condition?	/* Query the condition register of the questionable status register */
19	Return 0
20	:status:operation:condition?	/* Query the condition register of the

operation status register */

21 Return 256

22 *ESR? /* Query the event register of the event status register */

23 Return 0

24 :status:questionable? /* Query the event register of the

questionable status register */

25 Return 0

26 :status:operation?/* Query the event register of the operation status register */

27 Return 256

28 *cls /* Clear the status */

29 :measure:voltage:dc? /* Enable DC voltage function and make measurements */

30 Return -1.180686E+00

34 Return 0

35 :status:operation:condition?

36 Return 256

37 *ESR?

38 Return 0

39 :status:questionable?

40 Return 0

41 :status:operation?

42 Return 272 /* Change status and make measurements */

43 *cls /* Clear the status */

44 :trigger:single:triggered /* Execute the single trigger once*/

45 *STB?

46 Return 0

47 :status:questionable:condition?

48 Return 0

49 :status:operation:condition?

50 Return 256

51 *ESR?

52 Return 0

53 :status:questionable?

54 Return 0

55 :status:operation?

56 Return 288

/* change status, execute the single trigger once and

enter "wait to trigger" status */

Explanations:

1. Commands in line 2, 28 and 43 clear the current status (the value of the event status register and the error queue) of the status register. By using it every time when you query the register status, the interferences by existing information may be suppressed
2. Commands in line 3\~6 set the enable register of each register. As is shown in Figure 2-1, each register has a relationship with the status byte register.
3. Commands in line 16, 31 and 45 query the condition register of the status byte register. They are suggested to be executed before querying the status register, since every time the value of the register is changed, the condition register would be updated.
4. Command in line 27 returns 256, indicating the “event” was changed; line 42 returns 272, indicating the setting has been changed, the measurement “event” happen; line 56 returns 288, it indicates the setting has been changed, the instrument is waiting to trigger.
5. “*ESR”, “:status:questionable?” and “:status:operation?” query the each event register, and the value of them would be cleared every time after the query.
6. The first colon “:” in “:status:operation?” command can be omitted for being compatible with RIGOL and Agilent commands.

Example 8: Querying the Error Information

The status register provided enables user to diagnose the current error operation on the basis of its query function, searching the error reason. For the detailed commands, refer to Chapter 2. As the commands system of status register is in common use in all RIGOL, Fluke and Agilent, take RIGOL commands for example.

28 :calculate:statistic:min?

/* Beeping*/

29 SYST:ERR?

30 Return "setting unacceptable"

31 *esr?

32 Return 8

Explanations:

1. Commands in line 2, 9, 15, 21 and 26 clear the current status of the status register, the value of the event status register and the error queue. Execute “* cls” every time when you input new command for quering the register status, in order to suppress interference by information existed in register.

2. Commands in line 4, 10, 16, 22, 28 wigh beeping indicate the wrong operation.

3. SYST:ERR? is used to query the current error information.

4. *esr? is for query the error type, refer to Figure 2-1.

5. For line 4, the data returnedl covers the data in the last time and generate a "query interrupted" error. It is a query error.

6. For line 10, the character “*” attached before the command may cause a “synax error” error. It is a command error.

7. For line 16, the parameters should only be {RIGOL|AGILENT|FLUKE}, so null parameter is invalid, a "Parameter error" is generated. It is an execution error.

8. For line 22, the command has no data returned. If read the data forcibly, a "Query Unterminated" error will generate. It is a query error.

9. The command in line 28 queries the calculated minimum value, it should not be used in continuity test and diode measurement. Therefore, this command is wrong and which may disable the instrument and generate a “setting unacceptable” error. It is a device error.
