Hi Ed:
Great description of your test technique. BTW, I would think that the
temperature of the oil in the ladle should be specified, as this seems to be
a critical variable.
The temperature of the oil is established by the

Hi all,
I'm looking for information on lowering conducted power output on a cell
phone. The EUT is under FCC part 22/24 certification.
I am aware of the requirement to regrant a phone with a increase of power
output. Does the FCC care about a decrease in power output to the antenna?

An MOV won't work - it's a clamping device as opposed to a crowbar device.
Gas filled arrestors are common in the telecom industry -- try CP Clare,
Reltech (near Chicago), TII New York, Sankosha, Shinko, --- probably others,
but can't remember them.
Good luck

This question is in regard to the radiated immunity test specified in
section 3.3 of GR-1089-CORE in which the test signal is 80% AM modulated
with a 1KHz tone. In testing analog voiceband channels for idle channel
noise per section 3.5.3(c) of GR-1089-CORE, we have been using a

Hello All,
I will be buying a new PC for EMI/EMC testing. Can anyone suggest a mfgr. /

The defined I/O coupling methods for EN55022:1997 do not appear to
accurately depict real-world shielding provided by twisted pair
wiring, almost as if the test method were rigged against passing EMI
with T-P cable.
Considerable study went into development of

Hi Don,
Company B wants to OEM company A's product and assume that company A has,
in fact, done their job. hmmm
I would assume (ugh, there's that word again) that since you only referred
to the FCC, this product is only targeting the USA. In that light and in
