Hello Colleagues,
I was recently approached regarding the testing of DC conducted emissions on a
car charger for a 2 Way Portable radio and if it is required.
The applicable EMC standard per the RTTE Directive would be 301 489-5, which
basically falls back on 301 489-1 without any special
David –
You might consider ANSI T1.315-2001 “Voltage Levels for DC-Powered Equipment
Used in the Telecommunications Environment”. This standard contains tests
addressing transients, immunity, under voltage and others. There are some test
setups included.

Hello,
Does anyone know of a standardized test for simulating power glitches or
interruptions on the output of a DC power supply? I am not interested in
testing susceptibility of the AC power input but creating some sort of
standardized interruption of the DC supply's output voltage supply.

All,
I have this link: http://www.gost-r.info/what-russian-certification.php;

Hello, Kim.
CSA/UL 60950-1 made a conscious
Ghery makes two good points-
#1- Check with local authorities, not just customers- as
customers may not be up to date on accreditation rules.
#2- If a company is not marketing their product to the U.S.,
then perhaps NVLAP, A2LA and U.S. MRA's are not required.
Hi Eric,
Lots of luck, all of it bad! I did the NSA on the IBM/Siemens/Rolm 10 meter
chamber in Santa Clara about eight years ago and it was a struggle to get to
30 MHz. Admittedly, this was a pure 2 meter cone absorber (no tile), but I
haven't heard any success stories down at 13 MHz (not that
