Toggles the on-screen readouts on and off. Use when readouts overlay data, or to
eliminate blanking intervals in analog display.
Toggles spectrum analyzer power on and off. Green LED next to key is
illuminated when power is on.
Turning the knob clockwise increases CRT brightness.
The inner knob sets trigger level in INT, EXT, and (AC) LINE trigger modes (as
on a conventional oscilloscope), horizontal position in manual scan mode, and
picture framing in video monitor mode.
Outer knob controls volume of the AM and FM demodulators.
Lights when the AM or FM demodulators are active to indicate that the outer
knob of the LEVEL control sets the audio volume. See DEMOD on page 6–56.
Normally the spectrum analyzer smooths the detected signal with a video filter
having a bandwidth equal to the resolution bandwidth. The filter bandwidth is
indicated in the right-hand readout column. However, pressing [VID FLTR] (see
Figure 3–8) toggles an alternate, automatically selected or user-designated video
filter on and off. Its bandwidth replaces the normal video filter readout.
