momentarily
shorting TP2,
Shorting
TP3
reduces
the
level
required
to
trip
the
Attenuator/ RPP,
so
it
trips
on
the Generator's
own
output. This provides a
convenient
way
to verify the
operation of
the
entire
trip circuitry, although
at
a reduced
trip level
To
cheek
the trip function with TP3
shorted,
it is
best to
program
the Generator
to
an
output
level
of
+ 10
dBm;
then, program
it
for fixed
amplitude range ([SPCLir9ir
1
1).
This
allows the
level to
be varied from
a low
value
up
to the
maximum
value without
any
transients that might outherwise
trip the
RPP.
Then,
starting
at
a low
level,
such
as -10
dBM
(with the
RPP
reset), increase
(EDIT)
the
UUT
level in
1
dB
steps
until the
RPP
trips.
RPP
trip
normally
occurs between +10
and +15 dPm.
