I'm trying to use GNU Radio to build a test/measurement rig.
At a user-defined interval I want to perform two actions:
1) Transmit an FM sweep with user definable properties like frequency
2) And record to a file for a fixed duration.
But, short of using custom python blocks, I can't figure out a way to trigger the recording at the same time I perform the transmit and I can't figure out a way to stop the recording automatically after a fixed amount of time / samples.
