Click Mode Operating Instructions
Due to the complexity of the discontinuous disturbance test, this panel is
rather complex, as many parameters shall be defined.
However, the PMM 9010 has been designed to be extremely user-friendly
and to take care in a fully automatic way of all the necessary steps of the
test.
Due to the fact that the standard fixes the frequencies at which the test
shall be done, these frequencies are factory established and the User can
vary the other parameters only.
From the main window select SETUP and the main Setup panel will be
displayed.
The User can navigate through the different parameters rotating the control
knob.
In case an external attenuator is used to protect the input of the analyzer,
the value of this attenuator can be entered, in order to have the PMM 9010
taking count of the value in all the calculation of the measured levels.
The way to enter the value of the attenuator is the same adopted in all the
other modes (see for examples §4.1).
A 20dB external attenuator is provided in the PMM 9010-Click Option kit,
which has to be taken into account in this field when inserted at RF input.
Three most used limits are built-in into the analyzer: CISPR 14, CISPR22
and CISPR11.
Either one can be selected simply by pressing the relevant key.
The limit will be loaded and all the calculations will be done with reference
to the selected limit.
