The functions on this menu are used to calibrate the programmable gain
portion of the level control circuit (see
calibration is one of the processes which, in combination, insure that
absolute power levels at the test ports are accurate and repeatable.
Running this calibration takes about one minute.
For measurements in which absolute power levels are critical, perform this
calibration before every measurement calibration (see
power levels are not important, you can perform this calibration infrequently
(on a monthly basis, for example).
The detector gain calibration process causes some settings to change, and
these are not restored to their original conditions afterward. Therefore, after
the calibration, the system needs to be returned to a known state. The first
two softkeys (which combine the cal process with a user preset or factory
preset) are included in the menu as a convenience (and as a reminder of the
need to save the present settings before running the calibration).
