Tektronix VX4790A

This unit has an arbitrary waveform generator module that is a printed circuit board assembly designed for use in a mainframe conforming to the VXIbus specification.

It generates user defined waveforms of up to 262,144 voltage samples at sample rates of up to 25MHz using either the internal or external clock source.

One of the main features of this unit is its ability to vary the output frequency and amplitude of a stored waveform without having to resend the waveform from the system controller.

In addition, the ARB has sine, square, sawtooth, and triangular waveforms stored in internal memory, giving it many of the features of a function generator.
