The TGF4000 Series of Arbitrary Function Generators

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 µs to 500s. Burst mode operation allows for a userselected 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.

About this Guide

This Quick Start guide is for bench-top use of the TGF4000 Series comprising the TGF4042,TGF4082, TGF4162 and TGF4242 dual channel generators. A full Instruction Manual (English only) is also provided on the Aim-TTi website that includes comprehensive explanations of all functions and additional information on remote control, calibration, and the detailed technical specifications.

2 - Safety

General

2. SAFETY

General

This generator is a Safety Class I instrument according to IEC classification and has been designed to meet the requirements of EN61010−1 (Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use). It is an Installation Category II instrument intended for operation from a normal single phase supply.

This instrument has been tested in accordance with EN61010−1 and has been supplied in a safe condition. This instruction manual contains some information and warnings which have to be followed by the user to ensure safe operation and to retain the instrument in a safe condition.

This instrument has been designed for indoor use in a Pollution Degree 2 environment in the temperature range 5°C to 40°C, 20% − 80% RH (non−condensing). It may occasionally be subjected to temperatures between +5° and −10°C without degradation of its safety. Do not operate while condensation is present.

Use of this instrument in a manner not specified by these instructions may impair the safety protection provided. Do not operate the instrument outside its rated supply voltages or environmental range.

WARNING! THIS INSTRUMENT MUST BE EARTHED

Any interruption of the mains earth conductor inside or outside the instrument will make the instrument dangerous. Intentional interruption is prohibited. The protective action must not be negated by the use of an extension cord without a protective conductor.

When the instrument is connected to its supply, terminals may be live and opening the covers or removal of parts (except those to which access can be gained by hand) is likely to expose live parts. The apparatus shall be disconnected from all voltage sources before it is opened for any adjustment, replacement, maintenance or repair. Any adjustment, maintenance and repair of the opened instrument under voltage shall be avoided as far as possible and, if inevitable, shall be carried out only by a skilled person who is aware of the hazard involved.

If the instrument is clearly defective, has been subject to mechanical damage, excessive moisture or chemical corrosion the safety protection may be impaired and the apparatus should be withdrawn from use and returned for checking and repair.

Make sure that only fuses with the required rated current and of the specified type are used for replacement. The use of makeshift fuses and the short−circuiting of fuse holders is prohibited.

This instrument uses a Lithium button cell for non−volatile memory battery back−up; typical life is 5 years. In the event of replacement becoming necessary, replace only with a cell of the correct type, i.e. 3V Li/Mn0 accordance with local regulations; do not cut open, incinerate, expose to temperatures above 60°C or attempt to recharge.

20mm button cell type 2032. Exhausted cells must be disposed of carefully in

Do not wet the instrument when cleaning it and in particular use only a soft dry cloth to clean the LCD window.

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 etting-up a Square Wave Clock Signal

• S

NOTE

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

Initial Conditions

Before setting up the instrument for any of the examples, it should be returned to default conditions. To do this follow these steps:

• Press the hard key marked Utility

• Press the soft-key labelled System

• Press the soft-key labelled Default (display will show Restore Factory Default?)

• Press the soft-key labelled Yes

This sets the main waveform to Sine (10kHz, 1V pk-pk) and cancels any modulations, sweep, or burst triggering or gating.

The instrument can be set to remember its latest settings on power-off and restore them at poweron. This is set from the Utility > System menu and the PwrOn soft-key. This setting will be lost

when the instrument is restored to default conditions as described above.
