Description
When using a National Instruments AWG module or vector signal transceiver (VST), this attribute specifies the I-signal DC offset. Units are either percent (%) or volts (V), depending on the NIRFSG_ATTR_IQ_OFFSET_UNITS attribute setting.
PXIe-5673/5673E: Actual AWG signal offset is equal to the I/Q modulator offset correction plus the value specified by this attribute. When using an external AWG (non–National Instruments AWG), this attribute is read-only and indicates the I/Q modulator I-offset. Units are volts, as specified by the NIRFSG_ATTR_IQ_OFFSET_UNITS attribute.
Valid Values: -100 to 100% or -0.2 V to 0.2 V
Supported Devices: PXIe-5644/5645/5646, PXIe-5673/5673E, PXIe-5820/5830/5831/5832/5840/5841
