Calibration for NA, CAT, and VVM Modes
Mechanical Cal
Mechanical Calibration is performed using discrete standards from a Cal Kit.
Several Cal Kit definitions are built into the FieldFox. To learn about Cal Kit
definitions, refer to the Application Note, “Specifying Calibration Standards
and Kits for Keysight Vector Network Analyzers,” available online at
http://literature.cdn.keysight.com/litweb/pdf/5989-4840EN.pdf
Mechanical Cals are extremely accurate when performed using the correct Cal
Kits with standards that are clean and in good repair, and when using correct
connection procedures.
How to perform a Mechanical Cal
— Disconnect the DUT from the FieldFox.
— If a jumper cable or adapter is required to connect the DUT to the FieldFox,
then connect those components to the FieldFox connectors. The effects of
those components will be measured and removed during the calibration,
and only the effects of the DUT will be displayed in the measurement
results. These should be high-quality components!
— In NA, CAT, or VVM Mode, press Cal 5
.
