Measuring Power
You can use the following command to measure power.
:SENS{1-36}:CORR:OFFS:COLL:PMET
• Power measurement is required for scalar-mixer calibration, but
it is not required for 1-port calibration. The setting for power
measurement is the same as for the normal power calibration.
For information on power calibration, refer to Power Calibration.
Calculation of scalar-mixer calibration coefficient
If the needed measurement is completed for the calibration port and type
you have selected, use the following command to start calculation of
calibration coefficients.
:SENS{1-36}:CORR:OFFS:COLL:SAVE
• If the necessary measurement is not completed, an error will
occur. Once the calculation of calibration coefficients is
completed, the measurement values are cleared despite
whether they were used and error correction is turned on
automatically.
Turning ON/OFF scalar-mixer error correction
To turn on or off scalar-mixer error correction, use the following command.
This command is commonly used for the normal calibration; scalar-mixer
calibration data are enabled while the frequency offset is turned on, and
the normal calibration data are enabled while it is turned off.
:SENS{1-36}:CORR:STAT
• Once the scalar-mixer calibration coefficient has been
calculated, scalar-mixer correction is automatically turned on.
Implementing scalar-mixer calibration with ECal
An ECal (Electronic Calibration) module allows you to perform scalar-mixer
calibration and 1-port calibration without needing to replace the standard
device.
To perform ECal, use one of the following commands:
