15.2 Sweep Mode
The
Sweep mode
is used to operate the PMM 9010F as a scanning EMI
receiver. To enter this mode press the Sweep soft key on the main screen to
set the parameters for the scan. All the automatic settings (RBW, frequency
step, etc.) refer to the CISPR standard.

15.2.1 Ultra Fast FFT
scan
The Ultra Fast FFT (Fast Fourier Transform), as described at
§15.1.8
, allows
for assessing the EUT emissions across the whole spectrum in very short
time and in full compliance mode, thus avoiding the preliminary debugging
phases. The Ultra Fast FFT scan is also particularly suitable for those EUT
that cannot stay ON for a long time without getting damaged (e.g. small
electric motors, etc.) while maintaining the capability of performing a full-
compliant Quasi-Peak evaluation of all the frequencies.
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 input attenuation is Automatic or Manual and the set
attenuation and if the Minimum attenuation is 0, 10 or 20 dB.
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 4-1).
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.
