Measuring correction data
Measuring correction data
To measure each type of correction data, use the following command:
• [:SENSe]:CORRection:COLLect[:ACQuire] on page 237
For Open and SHORT correction, 120 Hz, 1 kHz and 1 MHz are measured and
each data frequency is saved. Therefore, even if the measurement frequency is
changed there is no need to reset the correction. The result is stored as the
data for normal operation when the multi-correction function is OFF and as the
data for multi-correction when it is ON (for the channel that has been selected
at execution).
For LOAD correction, the correction measurement is performed only for the
frequency specified at execution time.
Fixing the range at LOAD correction
When you want to fix the range at LOAD correction measurement, use the
following command:
• [:SENSe]:CORRection:COLLect:LOAD:RANGe:AUTO on page 238
The load correction is performed at the range specified by
[:SENSe][:FIMPedance]:RANGe[:UPPer] command on page 266, 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 235
• [:SENSe]:CORRection:CKIT:STAN3:FORMat on page 236
