SCPI Command
SYSTem:COMMunicate:ECAL:DATA? <path>, <impedance> [,<characterization>]
Description
Reads out the AutoCal module characterization data. One command call returns one S-parameter array according to the specified parameters. The data is thermo compensated or not depending on the current setting SENS:CORR:COLL:ECAL:THER:COMP. The array size is 2N, where N is the number of points of the specified characterization (See the SYST:COMM:ECAL:POIN? command). For the n-th point, where n is from 1 to N: <numeric 2n–1> real part of S-parameter at the n-th characterization point <numeric 2n> imaginary part of S-parameter at the n-th characterization point |

Parameter
<path>: {A|B|C|D|AB|AC|AD|BC|BD|CD|CHECk} specifies the port number or port pair or check state
<impedance>: {SHORt|OPEN|LOAD|OPEN2|LOAD2|S11|S12|S21|S22|…|S44} specifies the impedance state or S-parameter
<characterization>: {[FACTory]|USER1|USER2|USER3} specifies the name of the characterization, if omitted the factory characterization is used
The allowable combinations of parameter <path> and parameter <impedance> are as follows:
<path> |
<impedance> |
