Electrical calibration for differential OE measurements
To ensure the specified performance of the LCA, you should perform a full
three- port electrical calibration. See the Keysight website for applicable
calibration kits.
If you want to perform an OE user calibration (see page 61 for details), we
recommend executing a full four-port calibration, or a two-port calibration
between network analyzer ports 1 and 4, in addition to the three-port
calibration (see
Electrical calibration for single-ended measurements
Calibrate before you start using the Lightwave Component Analyzer
application. Alternatively, return to EE measurement mode, as described in
Returning to Electrical Measurements
on page 69, to calibrate.
NOTE
It is recommended to use the 6 mm and 14 mm torque wrenches
(Keysight part number 8710-2812 and 8710-2813, 45 N-cm/4 lb-in)
and a 12 mm wrench to tighten all RF connections during the calibration
