The NI Frequency Mask Trigger example uses 50% overlapping, length 1024 FFTs to continuously convert IQ data to the spectral data on an NI 5644R or NI 5645R FPGA. The spectral data is compared against a 1024 element user-definted mask. When this maks is violated, a reference trigger is asserted which causes NI-RFSA to acquire an IQ record.

The 100% POI duration is no better than 20 us for any device configuration.
