Short Name: IQ Out Port Term Cfg

Property of niRFSG

Specifies whether to use the I/Q OUT port for Differential configuration or Single-Ended configuration. If you set this property to Single-Ended, you must terminate the negative I and Q output connectors with a 50 Ohm termination.

If you set this property to Single-Ended, the positive I and Q connectors generate the resulting waveform. If you set this property to Differential, both the positive and negative I and Q connectors generate the resulting waveform.

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.

To set this property, the NI-RFSG device must be in the Configuration state.

PXIe-5820: The only valid value for this property is Differential.

Supported Devices: PXIe-5645, PXIe-5820

Default Value: Differential
