Preparation for Accurate Measurement (Executing Correction)
The load correction is performed at the range specified by
[:SENSe][:FIMPedance]:RANGe[:UPPer] command on page 262, when the function
is set to OFF.
Defining LOAD correction standard
Before measuring LOAD correction data, you must define the LOAD correction standard.
To define the LOAD correction standard, use the following commands:
•
[:SENSe]:CORRection:CKIT:STAN3[:DATA] on page 231
•
[:SENSe]:CORRection:CKIT:STAN3:FORMat on page 232
Reading/writing correction data (saving/recalling correction
conditions)
After saving the correction conditions to a file, you can recall these conditions on the
E4981A at any time from the file.
The correction data is set up in the parameter-oriented format shown in the table below:
Type of correction
G-B or Cp-G
(select with the
OPEN correction
[:SENSe]:CORRection:CKIT:STAN1:FORMat
command)
R-X or Ls-Rs
(select with the
SHORT correction
[:SENSe]:CORRection:CKIT:STAN2:FORMat
command)
Parameter format to define the LOAD correction standard
(select with the
LOAD correction
[:SENSe]:CORRection:CKIT:STAN3:FORMat
command)
To read/write the correction data, use the following command.
•
[:SENSe]:CORRection:DATA on page 236
The correction data written using the above command is handled as follows:
•
In case of STAN3: Saved as LOAD correction data for the measurement frequency
specified when the command is executed.
•
In case of STAN1/STAN2: Saved as OPEN/SHORT correction data for all frequencies.
•
Saved as the data for normal operation when the multi-correction function is OFF and
as the data for the multi-correction when it is ON (for the channel that has been selected
at execution).
