Digital Function Generator with LIN and LOG Sweep Modes

Toronto, Canada – GAO Tek Inc. ( has rolled out a digital function generator used to generate electrical waveforms. Available waveforms can be either repetitive or single-shot in which case some kind of triggering source is required. The digital function generator contains an attenuator, offers various means of 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.
GAO Tek Inc.’s digital function generator, model 8219A, operates in the frequency range of 0.3Hz to 3MHz or 0.5Hz to 5MHz. Waveforms includes Sine, Triangle, Square, Ramp, TTL and CMOS output. It boasts an external voltage controlled frequency (VCF) function, duty cycle control with signal inversion capacity, two-step and variable attenuation and a built-in 6 digit counter with INT/EXT function up to 100MHz. The function generator features variable DC offset control, high resolution, INT/EXT AM/FM modulation, LIN/LOG sweep modes and GCV output for synchronization.
