Hello,
I have the need to develop a very short delay trigger for the PXI-5671 hardware. I have played around with both the software and hardware triggers already and noticed that the delay times are almost too slow for the application my company would wish to use it for. Also, I noticed that the shortest delay is when the device has been moved to the initiated state but is waiting for the trigger before actually generating the signal. I also wish to have information embeded in the trigger that tells the PXI-5671 what frequency to generate a signal at. Unfortunately, I also noticed that once the device is initiated I am unable to modify the center frequency. Waiting for a trigger and then using the NI-RFSG initiate block takes too long for our application.
My question is: Is there a way to decrease the delay times as well as being able to configure the frequency at the same time or will there always be that trade off? The NI-RFSG initiate block just adds too much delay.
As a side note. I am able to use the PXI-5441 by itself because I am looking to do an HF only application, VHF/UHF would be something for the future. Please let me know if that would speed things up as well.
Also, please recommend any AWG hardware that may be faster at this application (i.e. cPCI, cPCIx, PXI, PXI-x, etc.)
Thank You,
