Specifies the instrument port to be configured to acquire a signal. Use RFmxInstr Get Available Ports VI to get the valid port names.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

On a MIMO session, this property specifies one of the initialized devices. Use "port::<deviceName>/<channelNumber>" as the format for the selected port. To perform a MIMO measurement, you must configure the selected ports property for the configured number of receive chains.

For PXIe-5830/5831/5832 devices on a MIMO session, the selected port includes the instrument port in the format "port::<deviceName>/<channelNumber>/<instrPort>".

Example:

port::myrfsa1/0/if1

You can use the RFmxInstr Build Port String VI to build the selected port.

Use "chain<n>" as the selector string to configure or read this property. You can use the RFmxNR Build Chain String VI to build the selector string.

Valid values

PXIe-5830 if0, if1
PXIe-5831/5832 if0, if1, rf<0-1>/port<x>, where 0-1 indicates one (0) or two (1) mmRH-5582 connections and x is the port number on the mmRH-5582 front panel
Other devices "" (empty string)

Default values

PXIe-5830/5831/5832 if1
Other devices "" (empty string)
