CALCulate<Ch>:DATA:CALL <Format>, <Data>...
The query reads the current response values of all S-parameter data traces at channel
<Ch>'s data access point <DACPoint>.
If a full n-port system error correction is active in the related channel, the command
reads the full nxn S-matrix of the calibrated ports (there is no need to create or display
the S-parameter traces). Use
available traces.
The "set direction" allows you to import measurement data at the "Fixture Simulation
Input" data access point (see
Note
●
Importing data is only supported in single sweep mode
CONTinuous
●
Before importing data, the channel must be configured with the same settings that
were used during export (user calibration, balanced port configuration, stimulus
axis etc.).
Furthermore the switch matrix configuration must match.
●
After importing data, "downstream" parameters in the data flow can be changed
and their effect is shown directly
●
Any request for new data from the hardware (Restart Sweep in single sweep mode
or switching to continuous sweep mode) discards imported data and switches back
the display to measured data

CALCulate:DATA:CALL:CATalog?
Query the traces available for CALCulate<Ch>:DATA:CALL?.
The response is 'S11,S12,S21,S22'.
CALCulate:DATA:CALL? SDATa
Return the complex response values of all traces. The traces in
the catalog list are read one after another: The response array
contains n (number of points) pairs of real and imaginary values
for S , followed by n pairs of values for S
