Models with Option Conditions Selection
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
Center frequency is < 25 kHz, or
CF >= 1 MHz and Span <= 141.4 kHz
and RBW <= 5 kHz
"Best Close-in"
on page 1066
All other conditions "Best Wide-
offset" on page
1067
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
