Operating Instructions
5.1 Introduction The PMM Click Generation (PCG) software is used to operate the PMM
CA0010 as a powerful instrument capable of generating the discontinuous
disturbances (clicks) dictated by the CISPR standard.
In details the PCG is able to generate all the CISPR 16-1-1 “Standard tests”
and “Annex-F Tests”.
It is also available the possibility of generating an arbitrary sequence of
pulses, not related to the ones dictated by the standard.
With this easy to use piece of software, the CA0010 becomes an useful test
that can be used both for checking the system itself and for verifying and
calibrating other click meters.
To enter this mode, simply run the software by double clicking its icon.
Immediately the main window pops up and allows the operator to choose the
test to be performed.
The PCA (PMM Click Generation) program is installed together with the
PCA (PMM Click Analysis software). Please follow the instructions
detailed in chapter 4 to install the package.
5.2 Signal
generator The internal signal generator is a high stability and accuracy, 50 Ohm RF
generator ranging from 150 kHz to 30 MHz.
It is not simply one generator but three in one!
It is capable of generating CW signals and also On-Off-Keyed signals and
CISPR Pulses.
It covers all of the four frequencies used for discontinuous disturbance
measurements: 150 kHz, 500 kHz, 1.4 MHz and 30 MHz.
As usual, to set a given frequency it is therefore enough to choose it from
the drop-down menu in the software.
It is able also to produce OOK modulated signals and CISPR Pulses
simultaneously. In this way, the unit can satisfy all the tests of the standard,
both for the base Table and the Annex F Table.
Levels, ON duration and OFF duration (separation) can be set as desired,
by entering the values in the corresponding boxes.
If a higher or lower level is needed, the User shall adopt either an external
amplifier or an external attenuator.
The internal generator is extremely useful for several applications: first of all
it is essential to calibrate the system itself, thanks to the automatic internal
routines specifically developed to this extention; then it can also be used to
transform the PMM CA00010 in a complete click meter test set.
