Making Measurements



Calibrate the N9330B before making measurements

3 Press

[ENTER]

to start calibration.

Calibrate with a T-combo calibrator

Using a T-combo calibrator is a three step process

requiring the user to manually change the

open-short-load components. The default order of the

calibration process is open-short-load.
1 Press

[CAL]

to bring up the dialog box for calibration

guidance.

2 Connect the “Open” component of the T-combo

calibrator to the RF OUT connector of the tester.



Press

[ENTER]

to start the open calibration.

3 Connect the “Short” component of the T-combo

calibrator to the RF OUT connector of the tester.



Press

[ENTER]

to start the short calibration.

4 Connect the “Load” component of the T-combo

calibrator to the RF OUT connector of the tester.



Press

[ENTER]

to start the load calibration.

A “Calibrated” indicator will be displayed on the upper

left corner of the screen when the calibration is

completed.

Using User Cal Mode

User Cal Mode

is an optional

selection when using a mechanical calibrator. The User

Cal Mode allows the user to choose one cal standard

from the open-short-load to perform a customized

calibration.

For example, pressing



[CAL] > {User Cal Mode} > {Open}

initiates a calibration

using the Open calibration standard only.

NOTE

Never connect an electronic calibrator to the tester until

after

powering on the N9330B.
