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 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.

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.
