Waveform Generator DAFG-1S
Programmable Digital Waveform Generator Module

Jump to: Technical Data Download Additional Information

This module is used as a part of high-voltage power amplifiers for driving piezoelectric actuators.

The waveform generator can produce preferably harmonic signals or a combination of them in a frequency region of up to several kHz. The signal output can be synchronized with external instruments via the trigger and synchronization inputs.

The device is equipped with an interlock loop that disables and shorts the output of the connected amplifier if it is opened. The device also contains a circuitry that scans the temperature measured by an external Pt1000 sensor.

The waveform generator is equipped with a USB data interface that allows the user to transfer waveform data to or from the device and to control it remotely.

Devices containing this module: HV-PA150-2D, HV-PA550-2D, DAFG-PS4-24V
