O POSITION-Controls the vertical position
of
the crt
display .
O Vertical Mode-Selects the vertical amplifier
operating mode .
CH 1 : Displays only signal applied to the CH 1
input connector . This button mustbe latched in
for X-Y operation .
CH 2 : Displays only signal applied to the
CH 2
input connector .
DUAL TRACE : Displays CH 1 and
CH
2 input
signals alternately . Chop or Alternate mode is
selected automatically by the SEC/DIV switch .
For SEC/DIV switch settings
of 1 ms and slower,
Chop is selected . For settings
of
.5
ms and
faster,
Alternate is selected . In DUAL TRACE mode, the
trigger signal is derived from CH 1 . When the
DUAL TRACE
and CH 2 buttons are locked in at
the same time, the trigger signal
comes from CH 2
(instead of CH 1) while DUAL TRACE signals are
displayed .

SOURCE-Selects the source of the trigger signal
.
INT : Uses a sample of the signal displayed on
the crt as a trigger signal in the CH 1 or CH 2
modes . In DUAL TRACE mode, the trigger signal
is obtained from CH 1 . If CH 2and
DUALTRACE
buttons are both latched in,
channel 2 is the
trigger source .
Line :

Uses a
sample
of
the power-line frequency
as
a trigger signal .
EXT :

Permits triggering on
signals applied to the
X (external trigger) input connector . External
trigger signals must be time-related to the
dis-
played signal for a stable display .
EXT=10 : External trigger
signal is attenuated by a
factor of
10 .
X-Y : Permits x-y display . X (horizontal) input is
through the X input connector . Y (vertical)
input
is normally through the CH 1
orY input connector
(vertical mode CH 1 button must be latched in) .
For special applications, the Y input may be
obtained from the CH 2 input connector (CH 2
button latched in), or from both CH
1 and CH 2
(DUAL TRACE button
latched in) .
