3.5 Pulse Generator Signals

The pulse generator provides single pulses with defined width and period or sequences
of pulses (pulse trains). In the example below, a single pulse with a width of 1.4

μ

s is

generated. The pulse is repeated after a pulse period of 5

μ

s. The second pulse generator

signal ("Sync" signal) can be used to synchronize data acquisition to the pulse.
