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
