Short Name: IQ Out Port Load Impedance

Property of niRFSG

Specifies the load impedance, in ohms, connected to the I/Q OUT port. 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.

Supported Devices: PXIe-5645, PXIe-5820

Default Value: 50 ohms if you set the IQ Out Port Terminal Configuration property to Single-Ended, and 100 ohms if you set the IQ Out Port Terminal Configuration to Differential.

Valid Values: Any value greater than 0. Values greater than or equal to 1 megaohms are interpreted as high impedance.
