Short Name: Reference Clock Rate (Hz)

Property of niRFSG

Specifies the rate of the Reference Clock. To set this property, the NI-RFSG device must be in the Configuration state. If you are using the PXIe-5654/5654 with PXIe-5696, the NI-RFSG device must be in the Committed state to read this property. When you read this property, it returns the frequency the device is locked to during the Committed state.

If you set this property to Auto, NI-RFSG uses the default Reference Clock rate for the device or automatically detects the Reference Clock rate if automatic detection is supported by the device.

Note  Automatic detection of the Reference Clock rate is supported on only the PXIe-5654/5654 with PXIe-5696. For all other supported devices, NI-RFSG uses the default Reference Clock rate of 10 MHz.

PXIe-5654/5654 with PXIe-5696: Values between 1 MHz to 20 MHz in 1 MHz steps are supported in addition to the Auto and 10MHz values.

Supported Devices: PXI-5610, PXIe-5644/5645/5646, PXI/PXIe-5650/5651/5652, PXIe-5653/5654/5654 with PXIe-5696, PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5820/5840
