The Wavetek 39 Universal Waveform Generator combines seven generators in one to provide extensive capabilities. It is an arbitrary waveform generator (arb), function generator, pulse/pulse-train generator, sweep generator, trigger generator, tone generator and AM modulation source. Arbitrary Waveform Generator. Model 39 is a powerful 12-bit arbitrary waveform generator with 65,536 points of waveform memory and clock speeds up to 30 MS/s. Up to 50 waveforms can be stored in non-volatile memory. Waveforms can be created and modified from the front panel or can be downloaded over the included RS-232 and GPIB interfaces with Wavetek's WaveForm DSP2 software. For complex applications, multiple waveforms can linked together in a sequence.
