Showing/Hiding the Sweep Counts
It is possible to have the trace legend display the number of sweeps included in the real time trace, peak
trace, average trace(if displayed), and any open stored traces. Most of the time, especially when the
tuner is sweeping the full 24 GHz span, the sweep count for the real time trace will just be 1. However,
when the tuner span is set to a small range, the tuner will sweep the given spectrum many times before
the display is updated. In these cases the sweep count for the real time trace could be as high as 100 or
more and the real time trace will actually be a peak trace of the sweeps that have occurred since the last
screen update. A sweep count of 582,282 for a peak trace indicates that there are 582,282 sweeps of
the spectrum included in that peak trace. A peak trace will continue building and its sweep count will
continue increasing until the peak trace is cleared (see page 35). The Average Trace sweep count will
indicate the number of sweeps included in the displayed Average Trace. Sweep counts are turned on by
default. To show or hide the sweep counts in the trace legend:

Adjusting the Input Attenuation
Since the OSCOR is a highly sensitive receiver, it is possible for very strong signals to have an overloading
effect on the receiver circuitry. Receiver overload (see page 63) is evidenced by strong signals appearing
at harmonic frequencies and/or from intermodulation distortion. The built-in attenuator should be
