Doc ID 022398 Rev 1

Conclusion:

Application functionality was not influenced by applied surges disturbance. The application

is pre-compliant to IEC 61000 -4-5 level 3 (2 kV line to line and 2 kV line to earth).

4.3

Radio disturbance characteristic according to EN55014

(CISPR14-1)

The demonstration board STEVAL-IHM036V1 was tested to be pre-compliant with CISPR

14-1 specification for conducted measurements for a frequency range from 150 kHz to

30 MHz. Test conditions with results are listed below.

Test condition:

●

Ambient temperature: 24 °C

●

Air humidity:

50%

●

Supply voltage:

230 VAC

●

Testing motor as load; electric output power equal to 50 W

Test signal: according to CISPR 14-1:

●

Frequency range 150 kHz - 30 MHz, detectors average and quasi-peak

●

Measured on power supply lines (AC line - L and N)

Conclusion:

The demonstration board STEVAL-IHM036V1 is pre-compliant with radio disturbance

according to CISPR14 for a frequency range from 150 kHz to 30 MHz with both, quasi-peak

and average detector. Figure 10 shows results of measured disturbance with average

detector.
