Short Name: Carrier Frequency

Property of niUSRP

Specifies the carrier frequency, in Hz, of the RF signal.

The overall carrier frequency is realized in hardware as a combination of frequency translation in the local oscillator (LO) and additional frequency translation implemented in the digital signal processing on the FPGA. To set the LO to a specific frequency, set the LO Frequency property.

The range of available values is hardware dependent. If you specify a value outside the range supported by your device, NI-USRP coerces the value to the nearest supported value. Writing to this property specifies the value you want to use. Reading from this property returns the actual value, which may have been coerced to the capabilities of the device. NI recommends that you read the value after you write to this property to determine the actual setting for the device.
