Factor f
For certain types of products that must be cycled to emit discontinuous disturbances 
(rather than run continuously), CISPR 14-1 requires users to operate the product over 
enough cycles to product 40 clicks. 
Factor f is used to calculate the click rate for these types of devices. See CISPR 14-1, 
Annex A Table A.2 for the factor to use for your specific DUT.
NOTE This information is given as an example. CISPR 14-1 is the reference document for 
disturbance measurement requirements. Refer to CISPR 14-1 to identify the test 
requirements for your specific DUT.
