I am currently trying to use one of the transmission channels on my 5423 AWG card to transmit RF pulses in order of 250us in length. I am in need of creating a trigger signal that transmits a digital TTL voltage signal to unblank the power amplifer for the pulses being made.
I don't have any additional AWG transmission channels so was hoping to use one of the digital trigger channels through the PFI port on the AWG card ?
I wondered if it would be possible to create a threshold filter that essentially transmits a positive trigger signal when the RF transmission on the AWG card is non-zero. Could this be done before transmission by creating a trigger waveform the same length as the RF waveform that is then transmitted by the trigger line in parralel to the RF transmission or would this need to be something that is calculated / run in real time ? If so how would I go about implementing something like this?
Or is there a way to transmit custom trigger signals anyway if I pass a signal waveform to it for transmission ? i.e. I make the trigger signal at the same time I make the custom RF pulse waveform as well, in a seperate MATLAB script.
I appreciate any advise at this time
