Boonton 4540 Series RF Power Meter
Operation 4-70
4.5.46 System > Calibrator Menu (External 1 GHz - optional)
The Calibrator Menu is used to seclect and control the external 1 GHz RF Calibrator (Model 2530). It can also select the 50
MHz internal calibrator. The external calibrator may be pulse modulated using either a built-in pulse generator, or via a rear-
panel BNC pulse input. Note that this menu does not contain any items related to sensor calibration—it is only for controlling
the calibrator for use as a signal source. For sensor calibration information, refer to Section 3.5 and Section 4.4.2 of this
manual.
