TGF4000 SERIES
40MHz, 80MHz, 160MHz & 240MHz
Dual Channel Arbitrary Function Generators
The TGF4000 series is the latest function/arbitrary generator series from Aim-TTi offering class-leading performance and unrivalled value for money.
A frequency capability of up to 240MHz is combined with two identical full performance channels that can operate as independent generators or in coupled or tracking modes. Precise channel to channel phase control with a resolution of 0.0010 is provided.
A wide range of built-in waveforms is included and custom arbitrary waveforms can be used at sample speeds up to 800MSa/s and replay rates up to 80MHz. PC based arbitrary waveform generation and editing software is provided. High resolution, low jitter pulses can be generated up to 100MHz as can wide bandwidth white noise.
An extensive array of modulations is provided using internal and external sources.
Gated, burst and sweep modes can use internal or external trigger sources. Remote control via USB and LXI compliant LAN (standard) can be supplemented by optional GPIB if required.

HIGHER FREQUENCIES
The TGF4000 Series out-performs other generators in its price range by offering high purity sine waves up to 240MHz and square waves up to 100MHz, with low harmonic distortion and low phase noise, audio band THD is significantly better than similar generators at just 0.05%.
EXCEPTIONAL FREQUENCY PRECISION
The frequency of these waveforms can be set with up to 15 digits or one micro hertz of resolution. The DDS based frequency generation system uses a high stability TCXO timebase oscillator.
HIGH FREQUENCY AND RESOLUTION PULSE
The pulse generator function offers an exceptionally high pulse width resolution of 100ps over a period range from 10ns to 1000s. The pulse edge speed is independently variable from 3ns to 800s. Pulse jitter is dramatically lower than any comparable generator at only 30ps.
PRBS GENERATOR *
PRBS (Pseudo-Random Bit Sequence) is a binary waveform type that is widely used within secure communications systems. PRBS is offered with a choice of 8 sequence lengths at rates between 1mbps and 100Mbps.
PRBS can be used as both a carrier waveform and a modulation.
HARMONICS GENERATOR *
The harmonics generator function built into the TGF4000 series enables waveforms to be created by the addition of sine wave harmonics.
Up to 16 harmonics can be used, chosen from up to the 50th order. The amplitude and phase can be individually set for each harmonic.
FREQUENCY COUNTER/TIMER
The frequency counter function allows external signals to be measured in terms of frequency, period, pulse width or duty cycle. The frequency range is 0.1Hz to 125MHz with a measurement resolution of up to seven digits. Both generator channels remain operational when the counter is in use.
EXTENSIVE DIGITAL & ANALOG MODULATIONS
A large set of modulation types are built-in including AM, FM, PM, FSK, ASK, BPSK, PWM and SUM. All standard and arbitrary waveforms can be modulated as the carrier, although Noise, Pulse and PRBS are limited to AM, ASK and SUM modulations plus PWM for Pulse.
INTERNAL DIGITAL MODULATIONS
AM, FM, PM, PWM and SUM modulations can use an internal modulation source based upon any standard or arbitrary waveform type or Noise. A very wide modulation frequency range of 1µHz to 10MHz can be used. FSK, ASK, and BPSK use a square wave modulation signal adjustable between 2mHz and 10MHz.
EXTERNAL ANALOG MODULATION AND TRIGGERING
All modulation types can use an external modulation signal, either analog (AM, FM, PM, PWM and SUM) or digital triggering (FSK, ASK, and BPSK). The analog modulation input bandwidth is DC to 5MHz.
SUM MODULATION *
SUM modulation, not offered by most other products, enables the modulation waveform to be added to the carrier at any percentage. All waveform types including Pulse and PRBS can be SUM modulated. This is particularly useful using Noise as the modulator to test circuit resilience with noisy signals.
WIDEBAND NOISE GENERATOR
The Noise function provides wideband gaussian noise at bandwidths up to 100MHz and crest factor of more than five. Noise can be used both as a carrier waveform and as a modulating waveform for AM, FM, PM, PWM and SUM modulation types. As a carrier it can be AM, ASK or SUM modulated.
BUILT-IN WAVEFORMS
A large number of standard and pre-built arbitrary waveforms are built into the generator. These include triangles, ramps, sinc, logarithmics, exponentials, gaussians and cardiac (among others). High sampling rate allows higher repetition rates than other generators.
CUSTOM ARBITRARY WAVEFORMS
Custom arbitrary waveforms of 16 bit vertical resolution and up to 8192 points can be defined and replayed at sampling rates up to 800MS/s and repetition rates up to 80MHz.
