Krzysztof, For question 2:
EN50082-1:1998 "Electromagnetic compatibility - Generic immunity st7andard Part 1. Residential, commercial and light industry" and EN50082-2:1995 "Electromagnetic compatibility - Generic immunity standard Part 2. Industrial environment" Call for both AM80% modulation (over 80-1000MHz) and keyed carrier 50% duty cycle (at 900MHz +/- 5MHz) for the radiated RF immunity tests.

For instance: IEC 1000-4-3: 1995 describes 80%-depth Amplitude Modulation with a 1kHz sinwave, ENV 50204: 1995 describes keyed carrier modulation (on-off, duty cycle 50%). My question is: do you know any standards (international, national, technical documentations, etc.) which describes different kind of modulations than these above (for instance AM with squarewave or Frequency Modulation or other ways of carrier keying) during tests. Would you please give me the number and title of the standards, frequency range, test levels and, of course, parameters of modulation. The second question: do you know any product, product family and other standards which call AM80%1kHz modulation and keyed carrier - cycle duty 50%.
