CALCulate<Chn>:TRANsform...
This subsystem converts measured data from one representation to another and controls the
transformation into the time domain (with option ZVAB-K2, Time Domain).
CALCulate<Chn>:TRANsform:COMPlex S | Y | Z
Converts S-parameters into matched-circuit (converted) Y-parameters or Z-parameters and vice versa,
assuming that port no. i is terminated with Z
0i
so that the three parameter sets are equivalent and the
following formulas apply:
<Chn>
Channel number used to identify the active trace. If unspecified the numeric
suffix is set to 1.
S | Y | P
S-parameters, Y-parameters, Z-parameters
*RST value
– (The initial representation of the trace is determined by means of
CALCulate<Ch>:PARameter:SDEFine)
SCPI, Command
Types
Device-specific, command or query.
Example:
*RST; :CALC:PAR:MEAS 'Trc1'", '"Y-S22'
Select the converted admittance Y<–S22 as measurement parameter of the
default trace.
CALC:TRAN:COMP S
Convert the converted Y-parameter into an S-parameter.
CALCulate<Chn>:TRANsform:IMPedance:RNORmal TWAVes | PWAVes
Selects the theory for the renormalization of port impedances. The selection has an impact on the
conversion formulas for wave quantities and S-parameters.
<Chn>
Channel number used to identify the active trace.
