(continued)
EXT
:
Provides a
trigger from
an external signal
connected
to
the
External
Trigger Input
connector. This
trigger input must
be time related to
the in-
put
signals
to
provide
a
stable
display.
EXT by 10):
The
same as
EXT
above, except
the
input
signal is
atten-
uated by a
factor
of 10.
34
COUPLING
1
j
Selects the method
used
to
couple signals
to
the
trigger generator.
AC:
Selects capacitive
coupling,
which blocks dc
components
on the signal.
Signals below
about 60
hertz are attenuated.
LF REJ: Selects
capacitive
coupling,
which blocks dc
components on the
signal. Signals
below about 50
kilohertz are rejected.
Useful for displaying
high
frequency
components of
complex waveforms.
HF REJ: Signals are
capacitively
coupled, which
blocks the dc component.
Signals below about 60
hertz and
above about 50
kilohertz are
attenuated.
Useful for
displaying low
frequency
components of
complex waveforms.
DC: All
components
of the signal
are coupled. Useful
for displaying low-
frequency or
low repetition
rate signals.
35
LEVEL
Selects the amplitude
point on
the trigger signal
at
which the sweep
is trig-
gered.
It
is usually adjusted after the trigger SOURCE, COUPLING, and
SLOPE have been selected.
36 SLOPE
Selects
the slope
of
the trigger signal on which the sweep is triggered.
OUT
-I-:
Sweep is triggered on the positive going portion of the trigger signal.
IN—:
Sweep is triggered on the negative going portion of the trigger signal.
37 External Trigger
Input
Connector
Connects external trigger input probe
or
cables
to the instrument.
38 ATRIGGER
HOLDOFF
Provides
control of
holdoff
time between sweeps. Variable up to ten times
the setting of the A TIME/DIV setting, except in
the .2
and
.5
second
ranges. Useful when triggering on
low repetition pulses or aperiodic signals.
Obtain
the best possible display using the
A
sweep trigger controls before
setting
the hold
off time.
39 Ground Binding Post External
connector to chassis
(earth) ground.
The
connector will accept
cables or wires using open end solder lugs, banana
plugs,
or stripped wire
for connection.
40
+A GATE
Provides
a
-t-5
volt positive pulse
output
during the
A sweep time.
41 -HB
GATE
Provides
a
-^5
volt positive pulse output during the
B
sweep time.
42
EXT Z AXIS
Connects external
Z-axis
inputs for
crt intensity modulation. External inputs
may also
be used for
crt
blanking provided
the crt
intensity
is properly
set. Useful for adding time markers
to a
display,
or
when using the instru-
ment
as a
peripheral display in
a
monitoring system.
43
CH 2
OUT
Provides an
output signal
from
the
CH
2
preamplifier. Useful for cascade
operation
(CH 2 into CH
1)
to
increase vertical
deflection sensitivity. Also,
may be used
to
trigger external equipment.
