Trigger output function of PGU
Using the Agilent 41501A/B contains PGUs, the 4155B/4156B can output a gate
trigger through the 41501A/B Ext Pulse Generator Trig Out terminal. The trigger
signal is synchronized with the PGU output pulses, and you cannot control trigger
timing.
The polarity of the trigger is positive and the output level is TTL.
The following figure shows the trigger signal. The leading-edge and tailing-edge of
the trigger are synchronized with the leading-edge and tailing-edge of PGU1.
This function allows you to perform multiple pulse outputs using external pulse
generators synchronized with the PGUs.
