The
following
signatures are for
the outguard
ALU
circuits.
The
signatures are
taken with the
start/stop
irtputs
of the signature
analyzer
connected
to
A3TP2.
NOTE
•To
obtain
this
signature,
a
10
K
resistor
must
be
connected between
the
S
volt
TP and
the
probe
tip
of
the signature analyter.
To
check
for
proper
signature
analyser connections
verify
signature
of
*S
V
test
point
Is
CH79.
