1. INTRODUCTION

The TGF4000 Series of Arbitrary Function Generators

This manual covers all four TGF4000 dual channel generators. Where there are differences in the specification, the limits for the TGF4042 & TGF4082 are shown in square brackets [ ] after the TGF4162 & TGF4242 limits.

These programmable function/arbitrary generators use direct digital synthesis techniques to provide high performance and extensive facilities in a compact instrument. They generate a wide variety of waveforms with high resolution and accuracy.

Sine waves are produced with low distortion to 160MHz/240MHz [40MHz/80MHz]. Square waves have fast rise and fall times at up to 100MHz [25MHz]. Linear ramp waves are produced to 5MHz. Ramp and square waves also have variable symmetry.

The instruments generate high resolution, low jitter, variable edge time pulses to 100MHz [25MHz] with variable period, pulse width, pulse delay, pulse edges and amplitude. Complex custom waveforms can be generated with 16-bit [14-bit] resolution and a sampling rate of 800MSa/s [400MSa/s]. Up to four waveforms can be stored in internal memory. Waveforms can also be generated by the supplied Waveform Manager Plus V4.13 Windows application and downloaded to the instrument via USB, LAN or optional GPIB interfaces or via a USB flash drive.

Front panel operation is straightforward and user friendly with all major parameters shown at all times on the large, bright, colour LCD. All major functions can be accessed with a single key or two. The knob or numeric keypad can be used to adjust frequency, amplitude, offset, and other parameters. Voltage values can be entered directly in Vpp or as high and low levels. Timing parameters can be entered in Hertz (Hz) or seconds.

Internal AM, FM, PM, ASK, FSK, BPSK, SUM* and PWM modulation make it easy to modulate waveforms without the need for a separate modulation source. Linear and logarithmic sweeps are also built in, with sweep rates selectable from 1 s to 500s. Burst mode operation allows for a user-selected number of cycles at each trigger event.

LAN and USB interfaces are standard and there is full compliance to 1.5 LXI Device Specification 2016.

The instruments use a high stability temperature compensated internal oscillator and the external frequency reference input lets you synchronize to an external 10 MHz frequency standard for even greater accuracy.

4. GETTING STARTED

In order to familiarise the user with some of the basic functionalities of the instrument, a number of set-up examples are shown in this guide.

It is recommended that all users should carry out the first four examples:

• Setting-up a Sine Wave Signal
- Setting-up a Square Wave Clock Signal
- Setting-up a Pulse Waveform
- Setting-up more Output Options

A number of further set-up examples are provided that assume some familiarity with the instrument:

• Setting-up an arbitrary wave signal
• Setting-up an AM modulated Sine Waveform
  • P RBS (TGF4162 & TGF4242)
  • Frequency Modulation of a Sine Waveform
  • Pulse Width Modulated Waveform (PWM)
  • Amplitude shift keying (ASK)
  • Frequency Sweep of a Sine Wave
  • Generating a Triggered Burst
  • Coupling the Frequency of Both Channels
• Frequency counter

For more detailed information on all functionality- see the full Instruction Manual.

Requirement

In the earlier set-up examples it was shown how the output menu is used to set the output level (amplitude plus offset or high level plus low level) and turn the output on or off. This example demonstrates the setting of output phase, output polarity, load impedance and voltage auto-range.

Starting Conditions

Before starting, reset the instrument to defaults as described in section 4 Getting Started

Open the Output Menu

• Press the soft-key marked Output

Sine Off Frequency: 10.0000kHz Amplitude: 1.000 Vpp Offset: +0.000 Vdc Load: 50 Ω Phase: +0.000° Range: Attn Auto Output: Normal CH1 Output Menu +0.000 ° Phase Type Range Load Align Done

Change the Output Phase

The soft-key labelled Phase will be selected as default.

• Enter a phase of -45 degree.

Sine Off Frequency: 10.0000kHz Amplitude: 1.000 Vpp Offset: +0.000 Vdc Load: 50 Ω Phase: -45.000 ° Range: Attn Auto Output: Normal CH1 Output Menu -45.000 ° Phase Type Range Load Align Done

The set phase angle is the point in the waveform period which is coincident with the Sync or trigger edge, i.e. it is the point in the period at which the waveform starts. Hence a negative phase setting advances, and a positive phase setting delays the waveform relative to the Sync or trigger; the waveform in the graph box changes to show this.

The Align soft-key is used to re-align phase when making frequency changes.

Change the Output Polarity

- Press the soft-key labelled Type to invert the output polarity.

Sine Off Frequency: 10.0000kHz Amplitude: 1.000 Vpp Offset: +0.000 Vdc Load: 50 Ω Phase: -45.000 ° Range: Attn Auto Output: Inverted CH1 Output Menu Output Type: Inverse Phase Type Range Load Align Done

Successive presses of the type key alternates between normal and inverted.

Change the Load Impedance

- Press the soft-key labelled Load

- Press the soft-key labelled Load again to change the load impedance to High-z (high impedance).

Sine Off Frequency: 10.0000kHz Amplitude: 2.000 Vpp Offset: +0.000 Vdc Load: High-z Phase: -45.000° Range: Attn Auto Output: Inverted CH1 Output Menu Load Impedance: High-z Phase Type Range Load Align Done

The default load impedance is 50 Ohms, but that this could be changed to any impedance between 50 and 10,000 Ohms. Levels are calculated based upon this impedance.

Successive presses of the Load key alternates between a numeric value and High-z. Note that the amplitude readout increases to 2 volts pk-pk.

- Press the soft-key labelled Load to return the load impedance to 50 Ohms.

Sine Off Frequency: 10.0000kHz Amplitude: 1.000 Vpp Offset: +0.000 Vdc Load: 50 Ω Phase: -45.000° Range: Attn Auto Output: Inverted CH1 Output Menu 50 Ω Phase Type Range Load Align Done

Changing the Range

- Press the soft-key labelled Range

Sine Off Frequency: 10.0000kHz Amplitude: 1.000 Vpp Offset: +0.000 Vdc Load: 50 Ω Phase: -45.000° Range: Attn Auto Output: Inverted CH1 Output Menu Range: Auto Phase Type Range Load Align Done

- Press the soft-key labelled Range again to change the range from Auto to Hold.

Sine Off Frequency: 10.0000kHz Amplitude: 1.000 Vpp Offset: +0.000 Vdc Load: 50 Ω Phase: -45.000 ° Range: Attn Hold Output: Inverted CH1 Output Menu Range: Hold Phase Type Range Load Align Done

Auto mode auto-ranges in 6dB attenuator steps (i.e. 'range' maximums of 10Vpp, 5Vpp, 2.5Vpp, etc., into 50Ω), with the amplitude range limited to 6dB to maintain waveform quality.

Selecting Hold mode disables auto-ranging; the attenuator setting is fixed and the amplitude range is no longer limited.

With range set to Auto the amplitude and attenuators will switch automatically and optimal performance will be realised. With range set to Hold a fixed attenuator setting is used for all amplitude settings.
