Toronto, Canada – GAO Tek Inc. has released a piece of digital function generator used to generate electrical waveforms. Available waveforms can be either repetitive or single-shot in which case some kinds of triggering sources are required. The digital function generator contains an attenuator, offers various means output waveform modulation, and has the ability to automatically and repetitively sweep the frequency of the output waveform between two operator-determined limits. This capability makes it very easy to evaluate the frequency response of a given electronic circuit.
This digital function generator, model 8219A, operates at the frequency range of 0.3 Hz to 3 MHz or 0.5 Hz to 5 MHz. Waveforms includes Sine, Triangle, Square, Ramp, TTL and COMS output. 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. The function generator features variable DC offset control, high resolution, INT/EXT AM/FM modulation, LIN/LOG sweep mode and GCV output for synchronization.
