This capability makes it very easy to evaluate the frequency response of a given electronic circuit. It can be used in such applications as audio response testing, vibration testing, servo system evaluation and ultra sound applications.

This professional digital function generator, model A0230001, offers adjustable sweep time and sweep width both in linear and logarithmic modes. It boasts external voltage controlled frequency (VCF) function; duty cycle control with signal inversion capacity, two-step and variable attenuator and a built-in 6 digit counter with INT/EXT function up to 100 MHz. Waveforms can be either repetitive or single-shot in which case some kind of triggering source is required.

Waveforms include Sine, Triangle, Square, Ramp, TTL and CMOS output. The function generator features variable DC offset control, high resolution, INT/EXT AM/FM modulation, LIN/LOG sweep mode and GCV output for synchronization. In addition, an oscilloscope may be connected to this instrument for output display.

This professional digital function generator belongs to GAO’s family of Logic Analyzer and Generator. The line includes DDS function generator or counter, Digital RF Millivoltmeter and Frequency Counter and Radio Frequency Signal Generator. This family provides an excellent tool for digital design verification and debugging. The family offers GAO’s customers various choices.
