VectorStar™ MS464xB Series Microwave Vector Network Analyzer Programming Manual : SCPI Commands : :CALCulate{1-16}:REFerence Subsystem
 
:CALCulate{1-16}:REFerence Subsystem
The :CALCulate{1-16}:REFerence subsystem commands configure various parameters related to the reference plane in line types such as coaxial, microstrip, and waveguides. Note that the per-port and per-trace reference plane extensions are independent. The commands for per-port are in this section while those for per-trace are in the :CALCulate{1-16}:PARameter{1-16}:REFerence Subsystem. Emulated instruments have different allowed choices (Lightning only uses per-trace reference plane extensions and HP8510 only uses per-port reference plane extensions), so behaviors may change when a non-native language is used.
