Sweep Mode Operating Instructions 4-1

4 - Sweep Mode Operating Instructions

4.1 Introduction

The Sweep mode is used to operate the PMM 9010 as a powerful scanning

EMI 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. All the automatic

settings (RBW, frequency step, etc.) refer to the CISPR standard.

Fig. 4-1 Sweep

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 activated 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 (e.g. FFT, etc.).

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.

Thanks to its digital architecture and to the clever design, the PMM

9010 receiver can make very fast measurements in the lower CISPR

band using the 200 Hz filter, yet maintaining full compliance to the

standards even in this very difficult condition.
