10.12.1 Introduction
The
Sweep mode is used to operate the PMM 9030 as a powerful scanning
receiver. To enter in this mode it’s enough to depress the Sweep soft key on
the main screen, and immediately the scan setup window pops up and allows
the operator to set the parameters for the scan.

As for the Analyzer operating mode, all the relevant information are reported
on the screen.
From the upper left corner, the User can see if the Preselector is ON or OFF;
if the Preamplifier is ON or OFF; which detector is in use and the relevant
hold time; if the function “Smart Detector” is activate and which one; if the
input attenuation is Automatic or Manual and the set attenuation and if the
Minimum attenuation is 10 dB or 0dB.
Just above the graph there is on the left the Reference level. During the
scan, in the center above the graph the actual frequency measured and/or
any other relevant operation.
Below the graph the start and the stop frequency, and loaded limits, if any.
When the sweep has been executed, on the bottom of the screen the most
important sweep parameters are repeated.
If the graph has been loaded from the memory, just below the start frequency
there is the symbol
# followed by the memory position loaded (position
number 2 in figure 10-16).
Please note that the information in the upper part above the graph refers to
the next sweep to be done, while the information in the lower part, below the
graph, concerns to the actual displayed data.
