Hey guys, I’m trying to do a simple experiment where both my DAQ (Data AcQuisition) card and my microcontroller trigger off the same signal. The trigger source is from the Agilent 33210A which is a 50 Ohm impedance output. From that source, I have connected it to both the AlazarTech DAQ card (50 Ohm Impedance) and my microcontroller (9S12E128) (Set to High impedance) I’ve noticed that my microcontroller is not triggering properly. When I disconnect the DAQ card, it works fine. I am suspecting that the low impedance on the DAQ card is clipping off the high voltages. I’m wondering if you guys have any ideas on how to fix this. I wouldn’t want (But if needed then I will) to introduce opamps or other circuits because it will create delays in the trigger signal.
