When reaches the upper frequency limit, the stop frequency is set to the highest
available frequency and the start frequency is changed to be less then the stop frequency
by the minimum span (1
one-half of the span, or to the stop frequency minus 500 Hz, and

The "Channel" parameter is coupled with the "Center
Frequency" parameter and is dependent on the Channel
Standard selected for the measurement. For instance, if the
"Channel Standard" selected is GSM–850, if the "Channel" is
set to 128 Fwd, the "Center Frequency" value is automatically
changed to 869.2 MHz. Conversely, if the "Center Frequency"
parameter is set to 893.8 MHz, then the "Channel" value is
automatically changed to 251 Fwd.

You cannot set the Start frequency equal to the Stop frequency. You
cannot select zero span by setting Start frequency equal to the Stop
frequency. The instrument will alter the value of the last setting to
maintain a minimum value of 1 kHz difference between the Start
and Stop frequencies.
The range values provided below are valid only in the Frequency
Domain. Time domain (zero span) values will be different.
