To access the CALIBRATE menu go to main menu in the vector voltmeter (VVM) application.
CALIBRATE Menu
 
START CAL
Starts Calibration.
CANCEL CAL
Cancels Calibration.
CAL SETUP
Opens CAL SETUP.
METHOD
Selects one of the following calibration methods:
 
• Full Reflection S11: Calibrates Port 1 for reflection measurements only. It requires three calibration components.
• 1P2P S11 + S21: Calibrates Port 1 for reflection measurements and S21 measurements only. It requires three calibration components and a through-line.
• Response S11 (Reflection Response, Port 1): Performs simple normalization for Port 1 reflection measurements only. It requires one short or open.
• Transmission S21: Forward Transmission represents the measurement in which the signal leaves Port 1 and is transmitted to Port 2. In this case an external USB power sensor is used as Port 2.
USER CAL
Turns the USER CAL on/off.
 
REFERENCE STATE
Sets the reference state of the end of the cable to either open or short when measuring the cable loss.
CAL INFO

CAL SETUP
The Cal Setup window displays a list of available calibration methods, Port 1 DUT connectors and Port 1 Cal Kits to choose from in order to perform VVM calibration setup and measurements.
From the main menu select CALIBRATE > CAL SETUP.
