 TG2511

Thurlby Thandar Instruments (TTi) has launched a reduced-cost version of its TG5011 function/arbitrary/pulse generator.

The TG2511 has a maximum frequency of 25MHz for sine and square waves and costs only about $1,320. It offers similar facilities to the more expensive 50MHz generator, but with proportionately lower maximum frequencies for pulse and arbitrary waveforms.

The generator comes with Waveform Manager Plus for Windows, enabling complex waveforms to be created using a PC. 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 offers 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 can be used as a modulating source.

Arbitrary waveforms of up to 128k words can be generated at 14 bits vertical resolution and a sampling speed of 125ms/s. A front-mounted USB port enables external flash memory storage of up to 1000 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.
