15-8 9010F Fast
15.1.6 Functional
description
The PMM 9010F features a completely new receiver architecture based on
the most recent DSP and FPGA technology:

15.1.7 Ultra fast
measurement: an
unique feature of
the PMM 9010F
Scanning the CISPR band A (9 ÷ 150 kHz) and band B (150 kHz ÷ 30
MHz)may require very long time, even several hours.
Thanks to its architecture, to the large internal memory and the built-in FFT
capability, the PMM 9010F can take a “snapshot” of the whole band in a
very short time and in full compliance with the CISPR requirements.
This feature greatly increases the productivity of the test laboratory, and
allows more comprehensive analysis of intermittent disturbances with an
irregular repetition rate.
According to the selected RBW, the whole spectrum or a portion of it is
analyzed by FFT in sequence.
The following table shows spans related to RBWs
RBW Real time Span [MHz] Over FFT [times]
300 kHz 33.5 1
100 kHz 3.76 2
30 kHz 1.6 6
10 kHz 2 16
3 kHz 0.65 16
9 kHz Cispr 1.84 16
200 Hz Cispr 0.041 16
