AV-153AH-B - Avtech Electrosystems Ltd. Function Generators

Avtech Electrosystems Ltd. AV-153AH-B Overview

The AV-153A series of high-power, high-voltage function generators allow sine, square, and triangle waveforms to be generated at amplitudes to +/- 200V and frequencies to 300 kHz, into loads of 5 kilohms and higher. These instruments also have a variable-gain linear-amplifier mode, which allows more complex waveforms (amplified from a low-voltage arbitrary waveform generator, for example) to be generated.

The AV-153A-B model provides sine wave, square wave and triangular waveforms at frequencies as high as 300 kHz with peak amplitudes as high as ±200 Volts (i.e. 400 Volts peak-to-peak) to loads of 5 kΩ and higher, with average output powers as high as 15 Watts. The closely related AV-153AH-B can operate into loads of 1.2 kΩ and higher, with average output powers as high as 50 Watts.

The sine, square, and triangle waveforms are bipolar. That is, they oscillate between a positive voltage and a negative voltage. All models also include a pulse mode of operation. The pulse mode allows the generation of a rectangular
pulse waveform that swings from zero Volts to a positive voltage. The pulse width is adjustable. The maximum pulse duty cycle is 80%. A DC offset feature is also included, which allows the waveforms to be shifted by an adjustable DC voltage.

Instruments with the -B suffix also include a complete  computer control interface. This provides GPIB and RS-232 computer-control, as well as front panel keypad and adjust knob control of the output parameters. A large backlit LCD displays the output amplitude and frequency.

An Ethernet port for Telnet-based control is optional.

A burst mode option is available. This allows the generation of a burst of 1-500 cycles of sine, square, triangle, or pulse waveforms. This burst may be triggered
by pressing a front-panel pushbutton, or by computer command.
