The

DELAY
TIME POS
Provides
a
variable B
sweep
delay from 0.000
to
10.000 times
the setting of
the A
TIME/DIV control.
31
TRIG MODE
Selects the
mode of
operation
for the A sweep
trigger.
AUTO: With
proper
trigger LEVEL
and
COUPLING
settings, A sweep
can be
initiated
by
signals above
about 20
hertz. In the
absence
of
a
triggering
signal or
with control
misadjustments,
the
A
sweep
generator
free-runs
to
provide a
reference display.
NORM:
With
proper trigger
LEVEL and
COUPLING
settings, A
sweep can be
initiated by
an input
signal. In the
absence of a
triggering
signal or with
con-
trol
misadjustments, the A
sweep
generator does
not run and
there
is
no
display.
SGL
SWP: A
momentary contact
push button,
which
cancels previous
TRIG
MODE selections
and selects a
single sweep
mode of
operation. This
mode
operates the same as
NORM, except
only one
sweep is
displayed on
a trig-
ger
signal. Another
single sweep
cannot be
displayed
until the
SGL SWP
push button is
pressed
to
reset the trigger
circuit.
32
TRIG
READY
Indicates the A sweep
is reset
and ready for a
single
sweep display
when
a
Indicator
trigger signal
occurs. If the
indicator is out
when in
the SGL
SWP mode,
the
SGL
SWP push
button must be
pressed
to
reset the
trigger circuit.
33
SOURCE
Selects the
source
of trigger
input
signal.
STARTS AFTER
DELAY
(B trigger
only):
B sweep
runs
immediately
after
the
delay time
selected
by the
A TIME/DIV
setting
multiplied
by the DE-
LAY TIME
POS
setting.
No
B trigger
is required.
In any
other
B trigger
SOURCE
setting
a
trigger
is required
after the
delay time
before
B
sweep
will run.
NORM:
Provides
a
trigger
from
the
vertical
deflection
system.
The
actual
source
is the
displayed
signal.
In this
mode, CH
1 and CH
2 time
relation-
ship
measurements
are not
valid and
should not
be used.
This mode
is
not
recommended
for
use in
the CHOP
or
ALT
VERT
MODE
because
the
dis-
play triggers
on
the channel
switching
transients.
CH 1 ; Provides
a trigger from
the CH
1
preamplifier.
The CH
2 display
may
be unstable
if it
is not time
related
to
CH
1
.
CH 2:
Provides
a trigger
from the
CH
2
preamplifier.
The
CH
1 display may
be
unstable if it
is not time
related
to CH
2.
LINE (A
trigger
only): Provides
a
trigger
from
a
sample
of the
power-line
frequency.
This
trigger is
useful when
channel
inputs are
time related
(multiple
or sub-multiple)
to the power-line
frequency.
Also, it
is useful
for
stabilizing
a
display
that has
a power-line
frequency
component
on
a com-
plex waveform.
