The results are calculated as follows:
●
BER
: The R&S
CMW compares the looped-back DL Data' (N bit) to the transmitted
DL Data (N bit). Assuming statistical independence of the bit errors the result is
equal to the BER of all N + n data bits.
●
DBLER
: The DBLER is calculated as the ratio of the number of looped-back data
blocks with bit errors to the total number of looped-back data blocks. The smaller
UL block size means that this result is a lower limit for the DBLER that would be
obtained by looping-back and evaluating all N + n data bits.

Measurement Results
All results of the Signaling BER measurement are shown in the lower left part of the
"BER" tab of the RX measurements view.
The results are described briefly below. For additional information concerning the mea-
surement procedures see
chapter 2.2.18.1, "BER, BLER and DBLER Tests"
