Click Rate
The click rate (N) is the key metric used to determine the click limit Lq. The
click rate is determined by counting the number of clicks per minute. The
determination of N is based on whether you are using continuous operation or
switching cycles to collect clicks. For devices that operate continuously:
N = n1/T,
where n1 = number of clicks during the operation time
T = observation time.
For certain appliances requiring switching operations as defined in CISPR
14-1, Annex A, N is calculated as:
N= (n2 * f)/T,
where n2 = number of switching operations during the operation time
f = factor given in CISPR 14 Annex A.
CISPR 14-1 requires that the click rate N be determined at:
— 150 kHz for measurements in the frequency range of
— 500 kHz for measurements in the frequency range of
In this application you have two choices of click rate to be used to determine
the click limit:
— MEASURED - the click rate measured from the particular signal under test,
— USER - a manually-entered click rate
Duration
Enables you to set the duration of the measurement.
Correction
This feature enables you to offset the amplitude of all measured values by the
value you enter.
Click Count
This feature enables you to use a fixed number of clicks to terminate the click
data collection cycle. The measurement will use both the number entered and
the set measurement duration as terminators for data collection.
