The Amplitude Menus
Note
The settings for sensitivity, video bandwidth and sweep time interact. If the sensitivity is set to manual, the video bandwidth and sweep time may be forced to Auto mode. If the video bandwidth is set to manual, the sensitivity and sweep time may be forced to Auto. If the sweep speed is set to manual and is set too fast, the OVER SWEEP indicator will come on in the display area. Since these settings interact, it is recommended that only one of the settings be changed, whichever setting is most important to the measurement task being performed.
