WPI A310 Accupulser, Instruction Manual

A310 Accupulser™ Pulse Generator

the pulse mode may be 
demonstrated with the panel controls 
set as follows. the instrument 
should provide the waveform shown 
on Figure , at the sYnc and the 
isolAtor outPut connectors.

Vary the three Pulse GenerAtor dials and notice how the waveform timing follows 
the dial values. note that the outPut light is dimly lit, reflecting the fact that the 
pulse width is /8 of the event interval duration. try to extend the pulse into the 

next event interval. this may be 
accomplished by increasing the 
delay or increasing the pulse width 
or decreasing the event interval. As 
soon as the pulse width overlaps the 
beginning of the next interval, the 
ViolAtion light should illuminate.    

switch sinGle/douBle Pulse to 
douBle and note that a second 
pulse appears as shown on Figure .
