Error term
parameters
String parameters describing the different error terms, depending on the current
calibration method; see table below. Each term contains one complex value (real and
imaginary part) for each sweep point.
Range [def.
unit]
The error terms consist of dimensionless complex numbers. The parameters must be
transferred in full length and have the following meaning:
'DIRECTIVITY' – Directivity at port <port1_no>
'SRCMATCH' – Source match at port <port1_no>
'REFLTRACK' – Reflection tracking at port <port1_no>
'ISOLATION' – Isolation between port <port1_no> and <port2_no>
'LOADMATCH' – Load match at <port2_no>
'TRANSTRACK' – Transmission tracking between port <port1_no> and <port2_no>
*RST value
–
The analyzer provides a default calibration corresponding to a test setup which does
not introduce any systematic errors; see
[SENSe<Ch>:]CORRection:COLLect:SAVE:SELected:DEFault
.
<port1_no>
Source port number.
<port2_no>
Load port number. If the error term is not related to the load port, a dummy number
can be used; e.g.
CORR:CDAT 'REFLTRACK', 1, 0
