This subsystem enables the virtual SAW Matching Network and defines its parameters. When the virtual network is enabled, port 1 serves as an unbalanced port, the physical ports no. 2 and 4 of the analyzer are combined to a logical (balanced) port no. 2.
Command tree: CALCulate<Chn>:FSIMulator
The commands in this subsystem are supported
for the sake of compatibility with older firmware versions. Starting with
firmware V1.70 the commands have been superseded by the command in the
CALCulate:TRANsform:VNETwork...
subsystem. Virtual network (de-)embedding is controlled by the Virtual
Transform
menu.
Selects the type of matching network to be simulated. The present firmware version provides a virtual matching network for DUTs with a single-ended and a balanced port.
Use this command in order to avoid problems should the
default value change in future firmware versions.
