Digital Storage Examples
Step 3. Toggle the STORAGE ON/Off switch to the Store ON
position.
Step 4. Select a VOL TS/DIV switch setting that gives the desired
vertical deflection.
Step 5. Set the SEC/DIV switch to display the reference signal
with the desired sweep rate (the fastest Store mode
sweep rate of the 2212 is 20 µs per division).
Step 6. Push the SA VE button to store the reference waveform
into the Reference memory.
NOTE
The VOLTS/DIV setting and the SEC/DIV setting of the refer-
ence waveform are not stored in the reference memory. The
settings of the reference waveform and the newly acquired
waveform must be identical to allow direct measurement
from the graticule. Cursors may be used to determine volt-
age or time differences.
Step 7. Acquire the new waveform that is to be compared with
the reference waveform.
Step 8. Push the RECALL ON/Off switch to display the stored
reference waveform on the crt screen.
NOTE
A RECALLed reference waveform will remain displayed until
the SA VE buton is pushed again. Then, a new reference
waveform is stored in the reference memory. Switching the
instrument to NON-Store removes the reference waveform
and the acquired waveform from the display, but the stored
reference waveform remains in the reference memory for use
upon return to the Store mode.
Step 9. You can use the Reference Position control (=TRace
SEParation control) to overlay the reference waveform on
the newly acquired waveform for making the comparison
(see Figure 3-12).
