9-6 Click Mode Operating Instructions
9.4 Report After a Click test the PMM 9010 reports all the relevant data.
Due to the complexity of the test and to the various conditions that may
happen during the measurement, several reports may be issued.
Here following some examples well representing the completeness and the
accuracy of the analyzer.
9.4.1 Fail during
determination of
the click rate N
In case a fail is recorded during the determination of the click rate N at the
frequency of 150 kHz, a report like the following is displayed (which is just
an example with a not-realistic N number):
If the fail occurs during the determination of the click rate at 500 kHz, the
report may be like this:
9.4.2 Report after a
successful test with
less than 5
instantaneous
switching a one
frequency
If the determination of the click rate N shows that at a given frequency (500
kHz in this examples) there are less than 5 instantaneous switching
operations, there is no need of any further test at that frequency or
frequencies (the investigation frequencies are 150 kHz for the interval from
150 to 500 kHz, and 500 kHz for the interval from 500 kHz to 30 MHz).
In the example L
q
is calculated for 150 kHz and no tests are done at the
other frequencies as the number in instantaneous switching at 500 kHz
during the observation time is less than 5.
