radiated HIRF testing levels modulations

2002-03-20 Thread shbeard

Please note that the following are personal comments and not those of my
employer.

I am looking for information both on the environments (assume aircraft)
that justify the following levels and the methods for testing.  I have been
asked to find EMI labs that can test to the following:

  900MHz - 1GHz   1100 V/m peak   1kHz pulse
modulation, 90% depth with a 1% duty cycle; in addition signal will be
switched on/off
  at a 1Hz rate (on 200ms; off
800ms)

Thanks in advance,
Susan H. Beard
EMC Consultant
