Function and arbitrary generator doubles frequency range to 40 MHz

08 May 2006

The TG4001, new from TTi (Thurlby Thandar Instruments), is a low-cost DDS function generator with arbitrary waveform capability that can generate high-purity sine waves up to 40 MHz and square waves up to 50 MHz: double the frequency of other function generators within a similar price bracket.In addition to sine and square waves, the new instrument can generate cosine, haversine, havercosine, pulse, triangle, ramp and sin(x)/x waveforms. Setting resolution is ten digits or 1 mHz.The TG4001 can generate not just pulses but complex pulse trains. A pattern of up to ten pulses can be quickly defined with each pulse having its own amplitude, width and delay. The whole pulse train pattern can then be replayed at a user-defined repetition rate.

As an arbitrary generator, the TG4001 can produce waveforms of up to 65,536 (64K) words at sample rates of up to 100 MS/s. Waveform Manager Plus software for Windows is supplied for the creation and editing of waveforms on a PC. Waveforms are downloaded to the generator using RS232 or USB interfaces.

A full voltage output signal from 5 mV to 20 V peak-to-peak EMF from 50 ohms is available over the full frequency range of the generator. Amplitude flatness for sinusoids is ±0.2 dB to 1 MHz and ±0.4 dB to 40 MHz. Pulse rise and fall times are less than 8 ns.

Modulation modes include wide-range phase-continuous sweep, AM, tone switching, and signal summing. A built-in trigger generator provides gated and triggered burst modes. All waveforms can be swept over their full frequency range at a variable rate.

The TG4001 includes both RS232 and USB interfaces as standard. These give full control of every instrument function as well as providing arbitrary waveform download capability. A GPIB (IEEE-488) interface is available as an option.

The generator is housed in a half-rack 3U case suitable for benchtop or system use. A rack-mount kit is available.

The TG4001 costs £995 (plus VAT) in the UK.
