character size and is calculated for a test level of A/m as follows: J= (3C + 1) 40 where jitter J and character size C are in millimetres As jitter is linearly proportional to the magnetic field strength, tests can be carried out at other test levels extrapolating the maximum jitter level appropriately d e f g h i EN 61000-4-20 may be used for small EUTs as defined in EN 61000-4-20:2003, 6.1
