3.8.3 Determination of N
As required by the standard, N may be determined either by counting the
clicks, or by counting the switching operations.
Fig. 3-6 Calculate N
Select Clicks if N has to be calculated on the number of clicks, or select
Sw.Op.+ or Sw.Op.- to determine N on the number of switching
operations, going up and down the list of the available options in terms of
switched current: 10mA; 20 mA; 50 mA; 100mA; 200mA; 500mA; 1A; 2A
and 5A. The current threshold value must be chosen in relation to the DUT
declared consumption.
Refer to § 3.10 for the connections to the internal LISN, required when you
need to measure the switching operations.
3.8.4 Factor f
The applicable standard may require a certain factor f to be used to
calculate the click rate N (see § 3.2.1). For example, table A2 of the
CISPR14 gives the factor f for several products.
This factor depends on the nature of the EUT and shall be entered by the
User in the normal way (see for example §3.2).
