1MA24: Calibrating the CMD Output Level for BER

Abstract
The CMD 57/59 output level for BER measurement can be calibrated to high accuracy to match GSM 11.21, (with modulated signals and adjacent timeslots + 50 dB above the used timeslot) using a simple test setup containing an NRVD power meter and an FSE spectrum analyzer.
