Group,
Does anyone know the appropriate frequency range and output power limitations
for an FCC approved 2.4 to 2.4835 GHz spread spectrum radio in Pakistan?
Or do you know a quick and easy way that I can find this information?
The transceiver radio is a frequency hopping ethernet modem (10-base
I believe that the lower bound of 450 kHz was chosen to also include 455
kHz, which is the common IF frequency of consumer AM radios.

John,
I was looking at my copy of 61000-3-2 to find the references you all are
making. My copy does not have a paragraph 6.2.3.3 for example. Then I
realized you are referring to EN 61000-3-2 : 2000. What I have is IEC
61000-3-2 : 2000.
Can anyone tell me that there is that big a difference
Neil,
If the power supplies are intended for audio equipment, where the peak
power required for some types of music can be 10 times the average
power, I could buy the manufacturer's explanation. Otherwise their
explanation of how they pass EN 61000-3-2:2000 sounds bogus to me.

If it is conducted emission through the power cord, then chances are that

Immediately upon entering the shielded box the mains leads should meet a

The following is a guess on my part. Most household breakers (USA) are 15
Amps for power wires that appliances can plug into. If a fault occurs, over
the time until the breaker pops, the time averaged current will be somewhat
in excess of 15 Amps. That means that the time-averaged hazard potent
