Preparation for Accurate Measurement (Executing Correction)
Executing OPEN/SHORT/LOAD Correction
Executing OPEN/SHORT/LOAD Correction
Turning ON/OFF correction function
To turn ON/OFF each type of correction, use the corresponding command below.
Executing the measurement of correction data with the
[:SENSe]:CORRection:COLLect[:ACQuire] command on page 233
automatically
measures data and turns ON the correction.
The measured value and the standard value is available to display or input using the
following parameters:
Measuring correction data
Measuring correction data
To measure each type of correction data, use the following command:
•
[:SENSe]:CORRection:COLLect[:ACQuire] on page 233
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:
•
