Until you familiarize yourself with the use of all controls,
the following procedure may be used to standarize the in-
itial setting of controls as a reference point and to obtain

Set these modes as follows;

waveform. If the waveform does not appear in the
display, adjust the VOLTS/DIV and y POSITION controls
to bring the waveform into the center portion of the CRT
display. Operation with a signal applied to the CH2 IN-
PUT (9) jack and the vertical MODE set to CH2 is similar
to the above procedure.
In the ADD mode, the algebraic sum of CH1 + C H 2 is

ed, the algebraic difference of the two
C H 1 —CH2 is displayed. If both channels are set to the
same VOLTS/DIV, the sum or difference can be read
directly in VOLTS/DIV from the C R T .
In the A L T or CHOP modes allow simultaneous observa-
tion of channel 1 and channel 2 waveforms.
In the CHOP mode, the sweep is chopped at an approx-
imate 2 5 0 kHz rate and switched between CH1 and
C H 2 . Note that in the CHOP mode of operation with the
SOURCE switch set to V. MODE, the trigger source
becomes the chopping signal itself, making waveform
observation impossible. Use A L T mode instead in such
cases, or select a trigger SOURCE of C H 1 , or C H 2 .
If no trace is obtainable, refer to the following TRIGGER-
ING procedures.

SLOPE controls @). The display on the screen will pro-
bably be unsynchronized. Refer to TRIGGERING pro-
cedure below for adjusting synchronization and sweep
speed to obtain a stable display showing the desired
number of waveform.
