Test Procedure:
The monitor Display set high-resolution mode, AC input use AC 240V.
Note :
7.10.1
IEC 61000-4-4 defines that power supply, I/O line, and control line all shall be
performed the transient test, but the I/O line and control line is applied with only
half of peak voltage (1 KV).
7.10.2
For the comparison of wave-shape generated by different generator, so the test
must uses a scope with at least 400 MHz bandwidth, and coupled to 50
Ω
to
monitor the rise-time, impulse, duration, and repetition rate of the impulses within
one burst.
