TTI launches low-cost generator version

Thurlby Thandar Instruments (TTI) has launched a lower-cost version of its TG5011 function/arbitrary/pulse generator that enables complex waveforms to be created using a PC.

The new TG2511 has a maximum frequency of 25MHz for sine and square waves and is priced at GBP795.

It offers similar facilities to the 50MHz generator but with proportionately lower maximum frequencies for pulse and arbitrary waveforms.

The generator comes with Waveform Manager Plus for Windows.

Commonly used waveforms that are pre-programmed into the software include sin(x)/x, exponential rise-and-fall, logarithmic rise-and-fall, Gaussian, Lorentz, haversine and cardiac waveforms.

The TG2511 features a set of digital modulations including AM, FM, PM, PWM and FSK.

The modulation source can be any standard or arbitrary waveform or any external signal applied to the modulation input from DC up to 20kHz.

A wideband noise generator creates Gaussian white noise with a high crest factor and a bandwidth of 20MHz.

Noise can be added to any waveform or be used as a modulating source.

Arbitrary waveforms of up to 128,000 words can be generated at 14-bit vertical resolution and a sampling speed of 125MS/s.

A front-mounted USB port enables external flash memory storage of up to 1,000 waveforms.

USB and LAN interfaces are provided as standard, the latter conforming with LXI Class C (Lan Extensions for Instrumentation).

A GPIB interface is available as an option.

All functions of the generator can be controlled from the digital interfaces and arbitrary waveform data can be transferred via them.
