Appendix C – R8100 Field Calibration Procedure
The R8100 series Communication Systems Analyzer does not typically require a field calibration once it
has left the factory. However, if instructed to do so by Freedom Communication Technologies technical
support, a field calibration may be performed. Specific instructions for performing a field calibration will
be provided by Freedom Communication Technologies technical support at the time such calibration is
needed.
If instructed to perform a field calibration by Freedom Communication Technologies technical support,
consider the following performance conditions:

The field calibration should only be performed in a stable room temperature environment of
approximately 70°F.

To ensure accurate results place the R8100 in Standard mode.

Perform a reset to factory configuration by pressing the front panel Test key followed by Presets…,
Load Factory Configuration.

Operate the unit for at least 30 minutes before continuing.

Make sure no cables are connected to the front panel. A 50-ohm load is not necessary since the
transmit signal is terminated internally.
Note: The Calibration menu status for both RF Input and RF Output will indicate “Incomplete” during
that part of the field calibration. Once each part is finished, the status will be marked “Complete.” This
feature is helpful in the event that power to the unit is lost during field calibration. Once power is restored
and the Calibration menu is navigated into, an “Incomplete” status will indicate that part of the field
calibration did not complete successfully and the procedure should be rerun.
