Calibration method
Calibration basically needs to be done every time the frequency range to be measured is changed. If the error is corrected correctly,
the calibration status display on the screen will Cn D R S T X be. n is the data number you are loading.
However, the N anoV N A can supplement the existing calibration information and give a somewhat correct display. This happens if
you change the frequency range after loading the calibration data. At this time, the display of the calibration status on the screen is
cn D R S T X . n is the data number you are loading.
1. Reset current calibration state CAL RESET
2. Connect the OPE N standard to the CH port CAL CALIBRATE OPEN and execute.
3. Connect the SHORT standard to the CH port CAL CALIBRATE SHORT and run.
4. Connect the LOAD standard to the CH port CAL CALIBRATE LOAD and run.
5. Connect the LOAD standard to the CH and CH ports CAL CALIBRATE ISOLN and execute. The CH port can be left
unconnected if there is only one load.
