3.1.9 Differential Phase Encoding (EDR) measurement
The measurement of the Differential Phase Encoding (
softkey) is an
enhanced data rate measurement (EDR). It checks whether the instrument modulates
the data correctly in the time range of the DPSK modulation. Correct modulation is
assumed if a specific bit pattern (PRBS9) is received from the sender. For each
packet, this pattern is checked and each positive test result is counted.
