of the trace, and interpolating to find the point where the integrated
power equals (1 – [Occ BW % Pwr]) / 2 (0.5% if, for example, the
99% occupied bandwidth is to be found) of the total power,
frequency f1 is obtained. This procedure is repeated from the upper
trace edge to find frequency f2. This calculation uses linear
interpolation to find the lower and upper carrier boundary point
within the width of a sweep point (the span divided by the number of
sweep points), f1 and f2

Spur Avoidance
Because VXT models M9410A/11A/15A/16A and M9410E/11E/15E/16E are direct-
conversion (zero-IF) receivers, feedthrough leakage from the local oscillator appears
as a spurious signal (spur) at the center frequency. The Spur Avoidance function is
provided to eliminate this spur, at the expense of some measurement speed.
When Spur Avoidance is enabled (the default), the instrument uses a software
algorithm to remove this spur from the displayed measurement data, but the
algorithm only operates under certain conditions. Specifically, it only operates in the
multiple capture case.
You can disable this function to speed up your measurement by setting Spur
Avoidance to “Disabled.”
Note that when Spur Avoidance is not in effect, either because you have disabled it
or because you are not in multiple capture, the following warning message will
appear in the status bar:
Settings Alert;Spur Avoidance Off
This is to alert you that measurement accuracy might be impacted by the fact that
Spur Avoidance is not in effect.
