Hallo, I am using a TEM Cell to measure
the Radiated Emissions for a microcontroller Core..
Strange but when i connected a empty TEM
cell to Spectrum anaylser there are some radiations
seen in low frequency and mobile range(This is understandable)
, Can anyone tell me why is this, what could be
done to improve or rather eliminate it..Are these
disturbances already considered in IEC specifications
or TEM cell has improper calibrations..
Please reply.,

Hi, have you checked your cables? If you
are using cables with bad shielding you might have
signals entering this way. Try also to put a 50ohm
load in the other end of the TEM. Last - it could
be stong signals entering your analyzer and you
then need a shielded room for your measurements.
