^ M E M O R Y POSITION Control
With selection of the S A M P L I N G C L O C K B control,
this control adjusts the vertical position of the stored
waveform. For memory operation in X - Y mode, the
control adjusts the X-axis position.

X - Y :
The instrument operates as an X - Y oscillo-
scope with C H 1 serving as Y - a x i s and C H 2 as
X-axis.
In memory operation, the waveform stored
with S A M P L I N G C L O C K A is displayed as
Y - a x i s input, and the waveform stored with
S A M P L I N G C L O C K B is displayed as X-axis
input.
The D E L A Y operation will not be produced
but only the N O R M operation will be pro-
duced even if the N O R M / D E L A Y selector is
set to D E L A Y .
J - A L T / m C H O P Selector:
Selects the display mode for two traces in the
D U A L mode.
J L A L T :
C H 1 and C H 2 aignals are alternately display-

m C H O P :
C H 1 and C H 2 signals are displayed by chop-
ping.
In memory operation, the alternate sweep
mode is automatically selected regardless of
the setting of this selector. Setting to display

CH2 INV Button
Inverts the polarity of C H 2 signal.
@
E X T T R I G Jack
When the S O U R C E control is set to the E X T position,
the sweep is triggered by the input signal fed through
this jack.
@
L E V E L / P U L L S L O P E (-) Control
L E V E L : Adjusts the trigger level, i.e., the point on the
trigger signal waveform slope where the sweep
starts.
P U L L S L O P E :
Adjusts the polarity of the triggering. When
the control is pulled out, the trigger occurs
at the trailing edge of the input waveform.
@
C O U P L I N G Switch
Selects the coupling for the triggering signal.
