Conducted
and
radiated interference
is within
the
requirements
of MIL
STD
461B
methods CE03
and
RE02.
Interference
is
also within
the standards
set by FTZ 1115.
Also
RF
leakage
of <0.5 ^V is in-
duced
in a
two-turn loop
2.5 cm in
diameter, held
2.5 cm
away from
any surface,
for
output levels
<0dBm.
Features
Sweeps between
two
selected end-points
in a
linear, step-wise manner.
End-points
can be
anywhere within
the
frequency range
of the
instrument.
In AUTO sweep mode, sweep must stay within
the
range
of
bands
2
through
9, or
band
1, or
band
10, or the HET
band.
Maximum sweep time: 999s. Minimum sweep time:
275 ms. A
maximum
number
of
distinct frequency points
is
automatically selected based
on the
end-points
and
sweep time.
Instrument sweeps between
two
selected end-points
in a
linear, phase
continuous manner.
End-points
can be
outside
the
band,
but
(Start Frequency
+
Stop Frequency)
H- 2
must
be
within
the
band.

by
selecting
a
frequency
span larger than
the

can
also
