Description
The PMM 9010 features a completely new receiver architecture based on
the most recent DSP and RSP technology, as shown on the diagram
below.

1.11 Ultra fast
measurement: a
unique feature of
the PMM 9010
In the CISPR band A (9 ÷ 150 kHz), the standards requires the use of a
200 Hz filter that is, by nature, a filter that implies a long measurement
time: a complete scan may require even more than 10 minutes, depending
the detector in use.
Thanks to its architecture and to the large internal memory capability, the
PMM 9010 can take a “snapshot” of the whole band in just one second
and, using a true built-in FFT capability, perfectly displays the complete
band in all its details. Later on will be then possible to make the QuasiPeak
evaluation of all the frequencies of interest after the measurements will
been taken.
This feature is not only useful to greatly increase the productivity of the test
lab, but also to make better and more comprehensive analysis in case the
disturbance to be evaluated is somehow intermittent and with an irregular
repetition rate; its analysis with a traditional receiver could be hardly made
in a proper way (even if an FFT capability is available: this feature needs a
very comprehensive design), as irregular pulses could be lost during a
usual sweep.
To be noted that during the FFT analysis the PMM 9010 makes use of
internal standard Gaussian filters in compliance with the norms, while in
other cases it uses filters mathematically modelled to the perfection using a
FIR technique.
