Short Name: IQ Out Port Offset
Property of niRFSG
Specifies the value, in volts, that the signal generator adds to the I and Q signals. To set this property, the NI-RFSG device must be in the Configuration state.
To use this property, you must use the Active Channel property to specify the name of the channel you are configuring. For the PXIe-5645, you can configure the I and Q channels by using I or Q as the channel string, or set the channel string to "" (empty string) to configure both channels. For the PXIe-5820, the only valid value for the channel string is "" (empty string).
|Note For the PXIe-5645, this property is ignored if you are using the RF ports.|
PXIe-5645: The waveform may be scaled in DSP prior to adding offset and the device state may be changed in order to accommodate the requested offset.
PXIe-5820: The waveform is not automatically scaled in DSP. To prevent DSP overflows, use the Pre-filter Gain (dB) property to scale the waveform to provide additional headroom for offsets.
Supported Devices: PXIe-5645, PXIe-5820
