Peak Voltage; Polarity; Repetition Frequency Of The Impulse: 5 Khz; Rise-Time : 5Ns ± 30 - DAEWOO ELECTRONICS DSL-15C1T Service Manual

TEST CONDITIONS & PROCEDURE: (Follow IEC 61000-4-4)
Test Condition:
The condition is base on operating with 50Ω load.

4.1 Peak Voltage

2 KV (applies the Level 3 typical Industrial Environment" of IEC
61000-4-4)

4.2 Polarity

4.3 Repetition Frequency of the impulse: 5 KHz.

4.4 Rise-Time : 5ns
4.5 Impulse Duration: 50 nS

4.6 Relation to Power Supply: Asynchronous

4.7 Burst Duration: 15 ms
4.8 Burst Period: 300 ms

4.9 Climatic Conditions

- Ambient Temperature: 15°C to 35°C
- Relative Humidity: 45% to 75%
- Atmospheric Pressure: 86 kPa to 106 kPa

4.10 Test Procedure

The monitor Display set high-resolution mode, AC input use AC 240V.
Note :
4.10.1 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).
4.10.2 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
impulse, duration, and repetition rate of the impulses within one burst.
