Tolerance Analysis
Due to the small measurement uncertainty of the CMU, the measuring equipment must meet stringent
requirements. Since the measurement uncertainty of the measuring equipment to be achieved depends
on the test setup used, it is recommended to perform a tolerance analysis.
To be able to trace back errors in the measurement, the measurement uncertainty should also be
indicated in the test report.
The tolerances given in the test report refer to the values specified in the data sheet, ie the
measurement uncertainties of the test setup used are to be taken into account as well.
Unless otherwise specified, the specified tolerances are always to be observed.
Note: Please take into account the ETSI Technical Report ETR 028.
The given tolerances refer to CMU data sheet 04/99.
