Remarks


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

On a MIMO session, this attribute 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 attribute 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 function to build the selected port.

Use "chain<n>" as the selector string to configure or read this attribute. You can use the RFmxNR_BuildChainString function to build the selector string.
