This
performance
test
verifies
that
the

meets
the
Spurious
Signal
specifica-
tion
in
Table
4-1.
Specification: dc to 200 MHz except where noted.
All
non-harmonically
related
signals
from
0
Hz
to
200
MHz
will
be
more
than
70
dB
below
the
carrier
or
one of
the
following
levels,
whichever
is greater:
Model 3336A Without Option 005 With Option 005
75 ohm output — 100 dBm —115 dBm
150 ohm output — 100 dBm — 100 dBm
(to 10 MHz) (to 10 MHz)
600 ohm output — 100 dBm — 100 dBm
(to 10 MHz) (to 10 MHz)
Model 3336B
75 ohm output — 100 dBm —115 dBm
124 ohm output — 100 dBm —115 dBm
135 ohm output — 100 dBm —115 dBm
600 ohm output — 100 dBm —115 dBm
Model 3336C
50 ohm output — 100 dBm —115 dBm
75 ohm output -— 100 dBm —115 dBm
® NOTE
Line related signals from the 600 ohm outputs will be more than 70
aB below the carrier or — 83 dBm whichever is greater.
