Trigger delay

Question asked by apl on Feb 18, 2015

I have a very general question. *I am using wide-band detection to measure response of a pulsed DUT.*
 
1) What is the difference between using NWA's own built in trigger delay and using an external pulse/trigger generator to delay the trigger? (I think it is different than narrow band detection)

For e.g a NWA has a minimum trigger delay of 10microsec. If we use an external trigger delay device,(min trigger delay ~2microsec) then would it not give better time resolution? I mean to say measure several points inside the pulse.

Please correct/suggest me.  

2) Point in pulse technique allows measurement of DUT response only when the pulse is on. How can we measure/observer DUT response when pulse is off? *+(My DUT has some response even in pulse off condition).+*

(I want to ask the same thing in Fig. 1 and Fig. 2-- even if they might be interpreted differently).
