Parameters:
<Capacitance>
Capacitance C<Cmp> for the specified circuit model.
Range:
-1mF to 1 mF.
Increment: 1 fF (1E-15 F)
*RST:
1 pF (1E-12 F)
Default unit: F
Parameters for setting and query:
<CircuitModel>
STSC | SCST | CSSL | LSSC | CSSC | SLCS | SCLS | SCCS |
STSG | SGST | GSSL | LSSG | GSSG | SLGS | SGLS | SGGS
Possible circuit models (character data); see
Example:
*RST; :SOUR:LPOR1 1,2; :CALC:TRAN:VNET:BAL:
DEEM:PAR:C2? CSSL
Create a balanced port and query the default capacitance C2 for
the Serial Cs, shunt L circuit model. The response is 1E-012 (1
pF).
CALC:TRAN:VNET:BAL:DEEM:PAR:C2 CSSL, 2.2E-12
Increase the capacitance to 2.2 pF.
Manual operation:
See
CALCulate<Ch>:TRANsform:VNETworks:BALanced:DEEMbedding<LogPt>:
PARameters:DATA<Port>
<Interchange>, <arg1>
Defines a deembedding network for a balanced port based on the given S-Parameter
traces.
Circuit models
STSL | STSC | SLST | SCST
require S-Parameter traces of two 2-
port networks, to be assigned to the different ports
PMAin
and
PSECondary
; the
FIMPort
model requires S-Parameter traces of a single 4-port network but no addi-
tional port assignment.
