OD1402 - Lesson 1/Learning Event 1
Learning Event 2:
INTERPRET THE VOLTAGE AMPLITUDE AND FREQUENCY MEASUREMENTS ON THE
BASIC OSCILLOSCOPE BY THE USE OF SCREEN GRIDS
SIMPLIFIED OPERATING PROCEDURES
The following methods are provided to aid in quickly setting the
oscilloscope controls to present a display. Before attempting
these procedures, the operator should become thoroughly familiar
with the functions of all controls, indicators, and connectors, as
described in Learning Event 1.
Single Trace Display
The following procedures will produce a display of the input signal
of one vertical amplifier, on one trace, by the dual time base. In
this case, the lefthand vertical amplifier is used. The right
hand vertical amplifier can be used by making the appropriate
changes to the procedure.
To produce a display of the input signal of the lefthand vertical
amplifier, use the following steps:
Step 1. Preset all the controls as described in Learning Event 1,
pages 13 and 14.
Step 2. Pull the POWER switch knob out to apply power and allow
the oscilloscope to warm up for five minutes or more.
Step 3. Turn the INTENSITY knob clockwise until a display is
visible. If no display is visible by the midrange position on the
INTENSITY knob, perform steps 4 through 8 below.
Step 4. Press and hold the BEAM FINDER switch.
Step 5. Set the VOLTS/DIV switch on the lefthand vertical
amplifier for a display that remains within the vertical area of
the screen.
Step 6. Adjust the POSITION knob on the lefthand vertical
amplifier for the desired vertical position of the display.
