3.1.9 Differential Phase Encoding (EDR) measurement
The measurement of the Differential Phase Encoding
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.
