Here is a quick reference for common EMC immunity tests for a given start frequency, stop frequency, and step size. Outputs are number of steps and time per test.
|Test||EN IEC 61000-4-6
|EN IEC 61000-4-3
|Start Frequency||150 kHz||80 MHz||1 GHz||1 GHz|
|Stop Frequency||80 MHz||1 GHZ||2.7 GHz||6 GHz|
|Number of Steps||633||255||101||182|
|Time per step||3||3||3||3|
This is just the test time per setup.
For the Conducted RF Immunity test, this should be multiplied by the number of ports under test.
For Radiated RF Immunity, this figure needs to be multiplied by 2 x antenna polarities and 4 x turntable positions, meaning the overall time is 8 times larger.
The outcome here is that to do a full radiated immunity test, from 80 MHz to 6 GHz, takes 3 hours. And that doesn’t account for setup time or investigating failures.
