10.
The
50
jt.
output
amplitude depends on
the
amplitude
MULTIPLIER
and
dial
setting.
On
the
Model
150, the
amplitude depends on
the
programmed am-
plitude.
11.
The
frequency
of the
50
jt.
output
waveform
depends on
the
frequency
MUL-
TIPLIER
and
FREQUENCY
IN
Hz
dial settings
on
the
Model
155.
On
the
Model
150, the
frequency depends on
the
programmed
amplitude
multiplier
and decades
12.
For
triggered operation turn
the
FUNCTION
switch on
the
Model
155
to
the
desired
waveform
or
TRIG.
For
the
Model
150,
program
the
desired
trig-
ger
waveform.
All outputs
will yield the
triggered
waveform.
13.
The
instrument
may
be triggered
by
either
the
ONE CYCLE
pushbutton
or
the
TRIG
IN
from
an
external
signal
generator.
All outputs
will
be
trig-
gered
at the
same
time.
The
ONE
CYCLE
pushbutton
is
found
on
the
front
panel
of
the
Model
155 only.
The
TRIG
IN
is
found
on
the
Model
155 front
and rear
panel.
On
the
Model
150,
it
is
on
the
rear panel
only.
14.
For
the
VCG
input
mode,
the
FUNCTION
switch
of
the
Model
155
must
be
turned
to
CONT.
For
the
Model
150,
the
continuous function
must
be pro-
grammed
.
15.
For
VCG
operation
the
VCG
signal
is
applied
to the
VCG
IN
from
an
exter-
nal generator.
For
the
Model
155,
VCG
IN
is
on
the front
and rear
panel;
and on
the
Model
150
it
is
on
the
rear panel
only,
16.
The Model
155
may
be
programmed
externally
in
exactly
the
same manner
as
the
Model
150.
The Model
155
may
be
totally
programmed
externally
or
any
one
of
the
controls
may
be
programmed
separately.
To program
externally,
turn
the
desired
MULTIPLIER
control on
the
front
panel
to
the
remote
(R)
position.
