The Input menu (see Figure 6–1) controls parameters that alter signal sensitivity,
change measurement amplitude units, and turn the calibration signal on and off.
The following procedure shows how to turn the calibrator on and off.
1. Press [INPUT] to call up the Input menu.
The word OFF following item 9 of the INPUT menu indicates the calibrator
signal is turned off.
2. Press [9] to turn on the calibrator signal.
The spectral display appears and the word CALIBRATOR is now displayed
at the lower right of the screen, indicating the calibrator signal is on. The
calibrator signal is the peak at center screen. Turning on the calibrator also
internally disconnects the RF input path from the RF Attenuator and
prevents viewing external signals.
3. Press [INPUT] again.
The word following item 9 now is ON. In this way, the menu enables you to
toggle between the two possible settings and displays the current setting.
4. Press [9] again to turn the calibrator off.
You get the spectral display back but without the word CALIBRATOR
displayed.
5. Press [INPUT] [9] once again to turn the calibrator back on.
