TEST LEVEL CALIBRATION
Rev050321
Using the
U
mr
Measurement Line calibration results, the
U
mr
value
calculated using Equation 3 can now be corrected using Equation 4. As
the calibration results are frequency-dependent, the corrections must be
applied with respect to frequency.
Again, for calibration to be performed at an
open circuit test level
of
10
Vrms
, and assuming a measured 31 dB loss for the
U
mr
Measurement Line,
which included the 30 dB attenuator and both cables:
So, when the measured value at the output of the attenuator connected
to the
150Ω to 50Ω Adapter connected to the EUT port of the
EM Clamp is
equal to the calculated
U
mr-ATT(xx)
value for any given frequency, the test
level has been achieved.
