Features
Sweeps between
two
selected end-points
in
a linear, step-wise manner.
End-paints 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)
+ 2
must
be within the band.
