Single Sweep Display
The 2212 single sweep store mode may be operated in the RECORD
mode or the ROLL mode. (RECORD mode from 50 ms/division to
20 µs/division, and ROLL mode from 50 s/division to 0.1 s/divi-
sion.)
NOTE
With the 2212 in ROLL mode, triggers are disabled, but not
in SGL SWEEP.
SGL Sweep Record Mode
With the 2212 is in the SGL Sweep Record mode, the last wave-
form acquired remains displayed. When you press the RESET
button, you rearm the trigger circuit to accept a new trigger event.
When that trigger event occurs, the full record is acquired and the
display is updated.
When the 2212 is in the SGL Sweep Record mode, theVertical
MODE in ALT and the Triggger SOURCE in VERT MODE, the
triggered channel behaves as just described. The non-triggered
channel is not updated. When you press the RESET button again,
the second channel is updated.
For SGL Sweep Record mode, you can use the following procedure:
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. Set the PRETRIGger switch to either 25% or 75% as
needed for your measurement.
Step 4. Apply a test signal to the CH 1 OR X input for setting the
trigger LEVEL control.
NOTE
For random signals, set the Trigger LEVEL control to trigger
the sweep on a signal that is approximately the same ampli-
tude as the random signal.
