INITIAL STARTING PROCEDURE
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

signal to the CH1 INPUT
VOLTS/DIV (2) control for a suitable size display of the
waveform.
If the waveform does not appear in the
display, adjust the VOLTS/DIV and • 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
displayed. If the CH2 INV (H| switch has been engaged,
the

difference
CH1 — 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 CRT.

The DUAL mode allows simultaneous observation of
channel 1 and channel 2 waveforms. The TRI mode
allows simultaneous viewing of channel 1 thru channel
3 input signals. In the TRI mode, either the CHOP or ALT
mode applies and must be selected.
In the CHOP mode, the sweep is chopped at an approx-
imate 250 kHz rate and switched between CH1 and
CH2. Note that in the CHOP mode of operation with the
and
SOURCE switch set to V. MODE, the trigger source
becomes the chopping signal itself, making waveform
observation impossible. Use ALT mode instead in such
cases, or select a trigger SOURCE of C H 1 , CH2 or CH3.
If no trace is obtainable, refer to the following TRIGGER-
ING procedures.

desired number of waveform.
TRIGGERING
The input signal must be properly triggered for stable
waveform observation. TRIGGERING is possible using the
input signal INTernally to create a trigger or with an EXTer-
nally provided signal of timing relationship to the observed
signal, applying such a signal to the EXT TRIG INPUT jack.
The SOURCE switch selects the input signal that is to be
used to trigger the sweep, with INT sync possibilities
(V.MODE, C H 1 , C H 2 , LINE) and C H 3 / E X T sync possibility.
