Hi all. I´m using the pna with an external trigger signal (edge trigger, bnc connector). When i send the trigger, i look at the pna screen, and the "arrow" moves about half a second after i send the signal. The pna screen reflects exactly when the measure is made? (of course, if it would be one microsecond, it wouldn't be noticeable anyway, but in this case is quite noticeable). I'm measure at 45 GHz, and the time between measures is in the miliseconds range. I suppose this time is a lot more needed for pna be ready for the next measure, right?

Thanks for your help.

p.s.: i don't know what time takes the trigger signal to build up, what it wouldn't be rare if it be quite slow. But i want to be sure the pna takes the measure as fast as the trigger signal appears. And if the screen reflects this measure.
