Operating Instructions—2213 Service
display size. Center the compressed display within the
graticule area using the Vertical and Horizontal POSITION
controls, then release the BEAM FIND push button.
4. Adjust the TRIGGER LEVEL control, if necessary,
to obtain a stable display.
5. Set the appropriate VOLTS/DIV switch(es) and
readjust the Vertical and Horizontal POSITION controls
to center the display within the graticule area.
6. Set the SEC/DIV switch for the desired number of
cycles of the displayed signal. Then adjust the AUTO
FOCUS control for the best-defined display.
MAGNIFIED-SWEEP DISPLAY
1. Obtain a Signal Display (see preceding instructions).
2. Adjust the Horizontal POSITION control to move the
trace area that is to be magnified to the center of the crt
graticule (0.5 division on each side of the center vertical
graticule line). Change the SEC/DIV switch setting as
required.
3. Pull out the SEC/DIV Variable knob (X10) to obtain
sweep magnification.
4. Adjust the Horizontal POSITION control for precise
positioning of the magnified display.
5. To calculate the magnified sweep speed, divide the
SEC/DIV switch setting by 10.
DELAYED-SWEEP DISPLAY
1. Obtain a Signal Display.
2. Select INTENS HORIZONTAL MODE and set the
DELAY TIME Range Selector switch to the desired amount
of delay time.
3. Adjust the AUTO INTENSITY control as needed to
make the intensified zone distinguishable from the
remainder of the display.
4. Adjust the DELAY TIME MULTIPLIER control to
move the start of the intensified zone to the start of the
point of interest on the crt trace. To capture an event
that occurs after the sweep ends, adjust the start of the
intensified zone past the end of the sweep.
X-Y DISPLAY
1. Obtain a baseline trace.
2. Use equal-length coaxial cables, or the two 10X
probes supplied with the instrument, to apply the hori
zontal signal (X-axis) to the CH 1 OR X input connector
and to apply the vertical signal (Y-axis) to the CH 2 OR Y
input connector.
3. Select X-Y mode by switching the SEC/DIV switch
to its fully counterclockwise position.
4. Advance the AUTO INTENSITY control setting until
two dots are displayed. The display can be positioned
horizontally with the Horizontal POSITION control and
vertically with the Channel 2 POSITION control.
NOTE
The display obtained when sinusoidal signals are
applied to the X- and Y-axis is called a Lissajous
figure. This display is commonly used to compare
the frequency and phase relationships of two input
signals. The frequency relationship o f the two input
signals determines the pattern seen. The pattern will
be stable only if a common divisor exists between
the two frequencies.
