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
1342 are actually the same as "Best
Close-in" on page 1341, 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

Center frequency is < 25 kHz, or
CF >= 1 MHz and Span <= 141.4 kHz
and RBW <= 5 kHz
"Best Close-in"
on page 1341
All other conditions "Best Wide-
offset" on page

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
