Overview
The Fixture Simulator provides the following functions:
 Matching Circuit Embedding
 Port Impedance Conversion
 Network De-embedding
 4-Port Network Embedding/De-embedding
 Balance-Unbalance Conversion (only 3-port/4-port models)
 Differential Matching Circuit Embedding (only 3-port/4-port models)
 Differential Port Impedance Conversion (only 3-port/4-port models)
Before you can use any of the features listed above, you must turn on the
desired feature individually and issue the following command to turn on the
Fixture Simulator:
:CALC{1-36}:FSIM:STAT
Matching Circuit Embedding
The Matching Circuit feature simulates the characteristics that the DUT
would exhibit when connected to a matching circuit.
On/Off
To turn on or off the Matching Circuit, use the following command:
:CALC{1-36}:FSIM:SEND:PMC:STAT
You can only turn on or off Matching Circuit for all the ports, not for each
port individually. However, any port whose circuit type is set to "None"
behaves as if this feature were permanently off.
