generate a train of pulse using an pxi-6220

[El_Tipo]

hello all,

I have an NI-PXI-1033 chassis with an NI-PXI-6220 module installed, an NI-PCIe card connected to the host computer, and finally connected to a  BNC-2090A connector.

I have been struggling trying to generate a pulse train signal (and connect an osciloscope to the bnc-2090a just to see the signal)but have not had any joy. i have looked some examples of other questions here on the forums with no luck. i read that the M Series devices do not have an independent DI or DO Start Trigger for digital waveform acquisition or generation and that you need to a trigger that initiates psignal pulses on the source.

i went to DAQmax asistant and selected "generate signal" then "digital Output" and then "line output" then chose phisical channel "line0/port0"

then on the configuration pannel i chose "N samples", now in the advance timing it only lets me choose "external clock" otherwise it complains.

how can i trigger the external signal PFI0?

Any help will be gratly apreciated.

just tried the "write Dig Chan-Ext Clock.vi" example and i can actually see the number of clock samples on the digital wavefor graph, now if i try to connect the osciloscope to the "DAQ/port0/line0" channel on the bnc2090a (which Iam assuming is the "p0" i get nothing on the osciloscope, maybe i would want to put a while loope somewhere on teh vi to make it run indeterminatly.. i also tried the PF0 on the bnc2090a but also got no reading on the osciloscope.

I don't know if this is exactly what you're trying to do, but you can generate digital waveforms with the counter on your card.  I just made and tried out this program and got the correct signal on my oscilloscope.

thank you AEN for your help. it was way more simple than i was attempting it.
