I'm trying to set up an 8267D to generate a pulse doublet, but no luck so far. The manuals have little to say about it - only that this mode requires an external trigger. I assume that means the Trigger In port on the rear panel. I've applied a trigger to every input on the front and rear panel to no avail. What determines the doublet spacing - the pulse delay field? The instrument has options 015, 1ED, 1EH, 520, 602, UNR, UNT, and UNU. Any help would be appreciated. Thanks.
Here is a example of how to set the Pulse Doublet: E8267D press: Preset, Freq 5Ghz, Amplitude 0dBm-> ALC off-> Power Search-> Power Search->Auto, RF on. Pulse->Pulse Source->Int Doublet->Pulse Width .5us->Pulse delay 2us->Pulse ON.
