Figure 3-4: CRT Display Controls
The INTENSITY STOREIREADOUT control sets the brightness of the read-
outs in the
NON-STORE mode as well as the intensity of the entire STORE
display. You can also toggle the readouts on and off by turning the larger
(outer) control fully counterclockwise and then back to the normal level.
Some readouts do not appear in both
STORE and NON-STORE modes.
Refer to Display Mode, page
2-6.
The FOCUS control adjusts the clarity of the display.
Finding "Lost" Displays
Because of signal variances or misadjusted front panel settings it is not
uncommon to "lose" a signal display. When this happens, use the following
procedure:
Step 1: Note which channel the signal is applied to and make sure the
vertical mode is set for that channel.
0 Step 2: Set the oscilloscope in the NON-STORE mode.
Step 3: Press the BEAM FlND button and hold it in. The beam of the
CRT is now intensified and compressed into the viewing area (Fig-
ure
3-5).
