class FetchStruct[source]

Response structure. Fields:

  • Reliability: int: See ‘Reliability indicator’

  • Cell_Name: List[str]: Name of the cell providing the measured connection

  • Ack: List[float]: Number of received acknowledgments as percentage

  • Nack: List[float]: Number of received negative acknowledgments as percentage

  • Dtx: List[float]: Number of missing answers (no ACK, no NACK) as percentage

  • Bler: List[float]: Block error ratio as percentage

  • Throughput_Avg: List[float]: Average throughput as percentage of scheduled throughput

# SCPI: FETCh:SIGNaling:MEASurement:BLER:RELative
value: FetchStruct = driver.signaling.measurement.bler.relative.fetch(algorithm = enums.Algorithm.ERC1)

Returns the relative DL results of the BLER measurement. There is one set of results {…} per cell: <Reliability>, {<CellName>, <ACK>, <NACK>, <DTX>, <BLER>, <ThroughputAvg>}, {…}, …

param algorithm:

Selects the formula for calculation of the BLER from the number of ACK, NACK and DTX. ERC1 (Default) : BLER = (NACK + DTX) / (ACK + NACK + DTX) ERC2: BLER = DTX / (ACK + NACK + DTX) ERC3: BLER = NACK / (ACK + NACK + DTX) ERC4: BLER = NACK / (ACK + NACK)

return:
