Store Mode Display
You set the conditions under which a waveform is acquired for
display with the front-panel control selections. Remember that:
- The display amplitude is controlled by the VOL TS/DIV
switches.
- The storage time base is controlled by the SEC/DIV switch.
RECORD Mode - The SEC/DIV switch will acquire and display
waveforms in RECORD mode from 50 ms/division to 20 µs/divi-
sion. A full record of the acquired waveform is updated each time
a trigger event is recognized.
ROLL Mode - The SEC/DIV switch will display and acquire wave-
forms in ROLL mode from 50 s/ division to 0.1 s/ division. Signals
are continously acquired and displayed. Triggers are disabled in
ROLL mode, except in SGL SWP.
In RECORD and ROLL digital store mode (no SGL SWEEP), you
can use the following procedure to display your signal:
Step
1.
Switch the 2212 on and obtain a baseline display in
Non-Store mode.
Step 2. Set the Store ON switch to the on state.
Step 3. Apply the signal to be displayed to the CH 1 OR X input
connector.
Step 4. Set the PRETRIGger switch to either 25% or 75% as
needed for your measurement. Adjust the Trigger LEVEL
for a stable display.
Step 5. Store mode displays can be expanded horizontally
with the Horizontal
Xl, XlO, X50
magnify switch.
