Description

Indicates the center frequency of the passband containing the upconverted RF signal. Writing a value to this attribute while using the PXIe-5644/5645/5646, PXIe-5672/5673/5673E, or PXIe-5820/5840/5841 device enables in-band retuning. In-band retuning increases the speed of frequency sweeps by reducing the amount of upconverter retunes.

Units: hertz (Hz)

Note This attribute is read/write on the PXI-5610, PXIe-5611, PXIe-5644/5645/5646, PXIe-5672/5673/5673E, and PXIe-5820/5830/5831/5832/5840/5841, and is read-only on the PXI-5670/5671.
Note Resetting this attribute disables in-band retuning, however, for the PXIe-5820, in-band retuning is always enabled.
Note For the PXIe-5820, the only valid value for this attribute is 0.
Note Setting this attribute while the PXIe-5644/5645/5646, PXIe-5673/5673E, or PXIe-5820/5830/5831/5832/5840/5841 device is generating has no effect until a dynamic attribute is set.

Supported Devices: PXI-5610, PXIe-5611, PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5820/5830/5831/5832/5840/5841
