Specifies the subset of ports, that are selected for full N-Port correction, where N is the number of ports specified in this property. Use comma-separated list of ports to specify multiple ports. The configured measurement is full N-Port corrected if both the measurement receiver and source port are specified using this property. The configured measurement is one-path two-port corrected if one of the measurement ports is specified using this property and another is specified using Correction Port Subset Response Ports. Measurements involving the ports outside Correction Port Subset Full Ports and Correction Port Subset Response Ports return error.

This property is used only when you set the Correction Enabled property to True and Correction Port Subset Enabled property to True.

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.

The default value is an empty string.

For example, when performing S11 error-corrected measurement for a 1-port DUT using a 2-port VNA and a 2-port calset, VNA generally acquires data by setting the source to port1 first and then to port2. In this case, to achieve faster measurement speed, set this property to port1, which lets the VNA acquire data using only source port1 and skips acquiring data with source port2.
