Description

This attribute offsets the NIRFSG_ATTR_UPCONVERTER_CENTER_FREQUENCY from the RF frequency. Use this attribute to keep the local oscillator (LO) leakage at a determined offset from the RF signal.

Note  You cannot set the NIRFSG_ATTR_UPCONVERTER_CENTER_FREQUENCY attribute or the NIRFSG_ATTR_ARB_CARRIER_FREQUENCY attribute at the same time as the NIRFSG_ATTR_UPCONVERTER_FREQUENCY_OFFSET attribute.
Note  Resetting this attribute disables the upconverter frequency offset.

Valid Values:

PXIe-5644/5645: -42 MHz to 42 MHz

PXIe-5646: -100 MHz to 100 MHz

PXIe-5840: -625 MHz to 625 MHz

Supported Devices: PXIe-5644/5645/5646, PXIe-5840
