A-Horizontal
deflection
is
provided by A
Sweep
at a
sweep
rate determined by the setting
of
the A
TIME/DIV
switch. Only A
Sweep
is
displayed; 8
Sweep
is
inoperative.
A INTEN-Displays the A
Sweep
at a rate deter·
mined by the A
TIME/DIV
switch. An intensified
portion
can
appear
on
the display during the 8
Sweep
time. This switch position provides
an
indication
of
both the duration
and
position
of
the
8
Sweep
(delayed
sweep)
with respect
to
the A
Sweep
(delaying
sweep).
AL
T -Alternates the displays between the A
I NTEN
and
8 D L
Y'D
Sweeps.
In A L T operation,
use
TRACE
SEP
to
vertically position 8 Trace;
use
8 INTENSITY control
to
adjust 8 Trace intensity.
8
DLYD-Displays
only the 8
Sweep.
The 8
Sweep
rate
is
determined by the 8
TIME/DIV
switch,
with
the delay time determined by the
setting
of
both the A
TIME/DIV
switch
and
the
DELAY
TIME
POSITION control.
@TRACE
SEP
Control-Positions the 8
Sweep
ver·
tically
when
the

bnc connector
provides a
sample
of
the
signal
applied
to
the Channel
1 preamplifier
via

connector.
@ EXT
Z-AXIS-Input
bnc connector permits the
application
of
an
external
signal
to
intensity mod-
ulate the
crt
display.
Does
not
affect display
wave-
shape.
Signals
with fast
rise
time
and
fall time provide
the most abrupt intensity
change.
Signals
must
be
time-related
to
the display
for
a stable presentation
on the crt. The connector
is
useful
for
adding time
markers in uncalibrated
modes
of
operation.
