Use hardware to generate a certain number of pulses using PXI-5652

[matt]

Is it possible to generate a certain number of periods (turn on the output for a predetermined amount of time using hardware with micro-second resolution) using the PXI-5652.

Hello Matt,

If you had a Vector Signal Generator, this would be more controllable using something similar to this forum.
Otherwise, the only way to control time on the 565x would be to use OOK modulation scheme. This will allow you to turn on the signal for a little time On and Off.
There is a shipped example called "565x Digital Modulation.vi" (on versions 1.3 and later of the RFSG driver) that can perform this task. Basically it uses the function named "niRFSG Configure Digital Modulation User Defined Waveform.vi" to write the user bit sequence and with property nodes you will configure the OOK scheme and the symbol rate (refer to specifications of your card for the possible values).
Hope this helps,
