Hello Group,
 
Does anyone know if there is an alternative conducted EMI power line
measurement method for CISPR 22? I'm having trouble testing a DC powered unit
with a traditional CISPR 16 LISN. Someone mentioned that a current measurement
can be made on power lines using a current clamp instead.
 
I could not find anything about measuring power lines with a current clamp.
What limits would be used? The only reference to current clamp measurements in
CISPR 22 is for telecommunication ports.
 
I know ANSI C63.4 mentions you can make measurements using a current clamp,
however CISPR 22 does not. Any information would be helpful.
 
Thanks,
Tim Pierce
