Non-Storage Examples
Example:
The signal applied to the CH1 OR X input connector contains
unwanted frequency components (see Figure 3-4A). If you want to
remove the undesired frequency components, you can use the
following procedure:
Step
1.
Switch the 2212 on and obtain a baseline display in
Non-Store mode.
Step 2. Apply the signal with the unwanted frequency
components to the CH1 OR X input connector.
Step 3. Apply the unwanted signal to the CH 2 ORY input.
Step 4. Toggle the Vertical MODE switch to ALT and set the
CH 2 INVert switch to INVert.
Step 5. Adjust the CH 2 VOL TS/DIV switch and VARiable control
to make the CH 2 display approximately the same
amplitude as the undesired portion of the CH 1 display
(see Figure 3-4A).
Step 6. Toggle the Vertical MODE switch to ADD and slightly
readjust the CH 2 V ARiable control for maximum
cancellation of the undesired signal component
(see Figure 3-4B).
