Hewlett-Packard, Model 3325A, Synthesizer/Function Generator (fig. 1-82), is a programmable signal source that provides
precision low frequencies from 1 Hz to MHz. It provides eleven digit resolution on five different waveforms; sine, square,
triangle, negative, and positive ramps. The square wave has rise and fall times of 20 ns. The following functions are
programmable: frequency, amplitude, phase, dc, offset, modulation, sweep parameters, amplitude calibration and self-
test. Ten storage registers are available for programming with ten different combinations of function/parameter settings
from the front panel controls, stored, and then recalled.
