5.
To
troubleshoot
the
Integrator board,
remove
the
Schmitt
Board
and
Range
and Trigger board.
Jumper
a
IK
resistor
from
pin
7
to
pin
18.
Apply
a
5
volt
peak
to
peak
triangle
wave
or
a sine
wave from
an
external
generator through
a
IK
resistor
to
pin
18.
This combination
will yield
an
operational amplifier with
a
gain
of
one.
Observe
the
output with
an
os-
cilloscope;
it
should be
a
5
volt
triangle
wave.
If
there
is
no
output,
use
the
Integrator
Amplifier schematic
to
troubleshoot
the
Amplifier.
NO OUTPUT
FROM
PROGRAMIvIED
BNC CONNECTOR.
(All
other outputs
performing
properly.
)
If
the
generator has
the
proper
output
on
the
fixed triangle, sine
and square
wave
outputs, but
no
output
on
the
50
j-l
variable
output,
check
the following:
1.
Make
sure
that the
FUNCTION
switch
is
set
on
CONT.
2.
Make
sure
that the
amplitude
MULTIPLIER
is
not
in
the
remote
(R)
position.
3.
If
there
is still
no
output, the
problem
is
on
the
Output Amplifier board.
Place
the
Output Amplifier on
the
extender board and troubleshoot using
the
schematic
diagram
of
the
Output Amplifier
in
the
back
of
the
manual.
