ELECTRONIC PRINCIPLES - OD1647 - LESSON 1/TASK 3
After all the controls are properly set, connect the
oscilloscope to a power source of the proper voltage and
frequency. Pull the POWER switch knob out to the switch stop to
apply power. Finally, allow the oscilloscope to warm up for 5
minutes or wore.
(2) Simplified Operating Procedures. The following procedure
is provided to aid in quickly setting the oscilloscope controls
to present a display.
(a) SingleTrace Display. The following procedure will
produce a display of the input signal of one vertical amplifier
on one trace of the dual time base. In this case, the lefthand
vertical amplifier is used. The righthand vertical amplifier
can be used by making the appropriate modifications to the
procedure.
Set the controls according to the procedures contained in
paragraphs 2d(l)(a) through 2l(l1) '(c), beginning on the
previous page. Connect the input signal to the INPUT connector
on the lefthand vertical amplifier. Then turn the INTENSITY
potentiometer clockwise until the display is visible. If no
display is visible by the midrange position, perform the
following steps:
Step 1. Press and hold the BEAM FINDER switch.
Step 2. Set the VOLTS/DIV switch on the vertical amplifier for
the display that remains within the vertical area of the
graticule.
Step 3. Adjust the POSITION potentiometer on the vertical
amplifier for the desired vertical position of the display.
Step 4. Adjust the POSITION potentiometer on the dual time base
for the desired horizontal position of the display.
Step 5. Release the BEAM FINDER switch.
Step 6. If necessary, adjust the LEVEL potentiometer on the
dual time base for a stable display.
Step 7. Adjust the FOCUS potentiometer for a welldefined
display.
