Description of command
These commands are always queries. They start a bit error rate test in the continuous repetition mode and output
the measurement results (see also detailed explanation of measured values in chapter 4). The results depend on
the measurement mode set via the
CONFigure:RXQuality:BAVerage<nr> :CONTrol
command (RFER,
BER etc.). They are
ProgressTime Relative progress of the measurement
ClassIIBits (Residual) bit error rate for class II bits
ClassIbBits (Residual) bit error rate for class Ib bits
BER Bit error rate (no distinction between bit classes)
FER Frame erasure rate
DBLER Data Block Error Rate
USFBLER USF block error rate, available for packet-switched channels only (CMU-K42)
CRCErrors Cyclic redundancy check (CRC) errors
Status Measurement status
The following messages can be output for the measurement status:
INV Measurement invalid invalid
PASS All tolerances matched passed
FAIL Not all tolerances matched failed
IMP Measurement impossible, therefore invalid impossible
