DSO Operators-How It Works
4.4
STORE OR NONSTORE DISPLAY MODE SELECTION
Press the
I'T""1
button to toggle the display mode between
STORE and NONSTORE.
Both modes are digital acquisition; the difference is in how the dis-
played waveforms are updated.
A
STORE mode display is held
between trigger events. The NONSTORE mode display is similar to
the display of a conventional (nondigitizing) oscilloscope and is
blanked between triggers. The effects on the display are most
noticeable in NORM Trigger MODE. The trigger point of a NON-
STORE display is near the beginning of the trace.
4.5
MENU AND SAVED WAVEFORM DISPLAYS CLEARING
Press the bezel button to remove menus and saved
waveforms from the display.
Menus and saved waveforms are cleared in a two-step priority when
both are displayed. Menu are cleared on the first press, and saved
waveforms on the second press.
A
displayed menu is also cleared
when a menu-select button is pressed or another control function is
selected.
4.6
CHANNEL SELECTION
Press the
[CW
or
(Cn
SELECTICOUPLING button to switch the
effects of the front-panel vertical control changes between CH
1
and CH
2.
The selected channel has its VOLTSIDIVreadout boxed in the display
whether on or off; but, if off, the word "OFF" is displayed in place of a
VOLTSIDIV setting.
A
second press of the button after the channel is
selected displays the Input Coupling menu (see para.
4.7).
