3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 29259 and the
following apply.
3.1
capacitive coupling clamp; CCC
special fixture that facilitates capacitive coupling of fast transient test pulses into signal
lines under test without any galvanic connection to the terminals of the circuits, or any
other part of the device under test (DUT)
3.2
degradation (of performance)
undesired departure in the operational performance of any device, equipment or system
from its intended performance
Note: The term "degradation" may apply to temporary or permanent failure.
3.3
direct capacitive coupling; DCC
method using discrete, non-polarized capacitor to couple fast and slow transient test
pluses into the DUT's signal lines
3.4
electromagnetic susceptibility
ability of any device, equipment or system failing to avoid degradation of performance in
case of an electromagnetic disturbance
Note: It has high sensitivity and low immunity.
3.5
inductive coupling clamp; ICC
bulk current injection (BCI) type probe to provide the means of coupling slow transient test
pulses into signal lines under test without any galvanic connection to the terminals of the
circuits, or any other part of the DUT
