S820E UG PN: 10580-00343 Rev. H B-7
Measurement Review B-2 Measurement Overview
Calibration
For accurate results, the instrument must be calibrated before making any
measurements.
The Cable and Antenna Analyzer mode requires calibration standards or
external sensors, which are sold separately.
The instrument must be re-calibrated whenever the temperature exceeds the
calibration temperature range window or whenever the test port extension
cable is removed or replaced. The instrument must also be re-calibrated every
time the setup frequency changes. Refer to Chapter 4 for details on how to
perform a calibration and the various calibration options available for coaxial
cable and waveguide measurements.
Note
Anritsu recommends allowing the S820E to warm up for at least
10 minutes to typical operation temperature before calibrating.
The instrument will require a new calibration if the internal
instrument temperature changes more than ±10 ºC after
calibration.
The external InstaCal Calibration Module is NOT compatible with
the Microwave Site Master S820E.
