Specifies the expected carrier frequency of the incoming signal for demodulation, in Hz. The NI-RFSA device tunes to this frequency. NI-RFSA may coerce this value based on hardware settings and the RF downconverter specifications.

Note For the PXIe-5645, this property is ignored if you are using the I/Q ports.

Default Values:

PXIe-5644/5645/5646, PXIe-5840/5841/5860, PXIe-5842 (500 MHz, 1 GHz, and 2 GHz bandwidth options): 1 GHz

PXIe-5842 (4 GHz bandwidth option) using the Standard personality: 1 GHz

PXIe-5842 (4 GHz bandwidth option) using the 4 GHz Bandwidth personality: 6.5 GHz

PXIe-5820: 0 Hz

PXIe-5830/5831/5832: 6.5 GHz

All other devices: 100 MHz
