Note that in these models, the
hardware does not actually provide for
an extra-fast tuning option, so the
settings for "Fast Tuning" on page 962
are actually the same as "Best Close-
in" on page 961, but the rules are
implemented this way so that the user
who doesn't care about phase noise
but does care about tuning speed
doesn't have to remember which of
the other two settings gives faster
tuning
Span > 12.34 MHz, or
RBW > 250 kHz, or
Source Mode is set to “Tracking”
"Fast Tuning" on
page 962
Center frequency is < 25 kHz, or
CF >= 1 MHz and Span <= 141.4 kHz
and RBW <= 5 kHz
"Best Close-in"
on page 961
All other conditions "Best Wide-
offset" on page
961
In all the above cases:
–
The RBW to be used in the calculations is the equivalent –3 dB bandwidth of the
current RBW filter
–
The rules apply whether in swept spans, zero span, or FFT spans
