!ong Term
If you are replacing the Sensor Module with another Sensor Module,
refer to Appendix B in
this
guide for the procedure for entering the
calibration data for the new Sensor Module into the HP 8901B.
Short Term
If you are only using the new Sensor Module temporarily, you can
manually enter the appropriate cal factor for each RF Power measurement.
(Refer to your HP 8901B Operation and Calibration Manual for the
procedure and considerations for manually entering cal factors.)
Interchangeably
If you plan to use two sensors interchangeably, a second storage
table is available in the HP 8901Bs non-volatile memory. This table
is designed to be used in the instrument's Frequency Offset Mode.
(In this mode an external local oscillator (LO), a microwave down-
converter, and a mixer are typically used to extend the frequency
range of the HP 8901B. Refer to your HP 8901B Operation and
Calibration Manual for details on using the Frequency Offset Mode.)
