You can use the following procedure to display signals with the
2212 osciloscope in the X-Y Non-Store mode:
Step 1. Switch the 2212 on and obtain a baseline display in
Non-Store mode.
Step 2. Rotate the INTENSITY control fully counterclockwise.
Step 3. Apply the vertical signal (Y-axis) to the CH 2 ORY in-
put connector. Apply the horizontal signal (X-axis) to
the CHl OR X input connector.
Step 4. Toggle the vertical MODE switch to X-Y.
Step 5. Increase the INTENSITY until the display is visible.
If the display is not visible with the INTENSITY control
at midrange, press and hold in the BEAM FIND button
while adjusting the CH 1 and CH 2 VOL TS/DIV
switches until the display is reduced in size, both
vertically and horizontally. With the BEAM FIND button
still pressed in, center the compressed display with the
POSITION controls (CH 2 POSITION control for vertical
movement; Horizontal POSITION control for horizontal
movement). Release the BEAM FIND button and adjust
the FOCUS control for a well-defined display.
NOTE
The display obtained when sinusoidal signals are ap-
plied to the X- and Y-axis is called a Lissajous figure.
This display is commonly used to compare the
frequency and phase relationship of two input signals.
The frequency relationship of the two input signals
determines the pattern seen. The pattern will be stable
only if a common divisor exists between the two
frequencies.
