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 150 Ω to 50 Ω Adapter connected to the EUT port of the CDN is
equal to the calculated U
mr-ATT(xx)
value for any given frequency, the test
level has been achieved.
