Response structure. Fields:

  • Reliability: int: See ‘Reliability Indicator’ Zero reliability indicator indicates that the results in all measured segments are valid. A non-zero value indicates that an error occurred in at least one of the measured segments.

  • Number_Of_Results: int: Total number of segments to be displayed Range: 0 to 10

  • Seg_Reliability: List[int]: Reliability indicator for the segment. The meaning of the returned values is the same as for the common reliability indicator, see Reliability parameter.

  • Rx_Quality_Full: List[int]: RX quality full as dimensionless index measured over the full set of TDMA frames Range: 0 to 7

  • Rx_Quality_Sub: List[int]: RX quality sub as dimensionless index measured in a subset of 4 SACCH frames Range: 0 to 7

  • Mean_Bep: List[int]: Mean BEP as dimensionless index Range: 0 to 31

  • Cv_Bep: List[int]: Coefficient of variation of BEP as dimensionless index Range: 0 to 7

  • Number_Of_Blocks: List[int]: Number of already correctly decoded blocks Range: 0 to 24

  • Tdma_Frame_Nr: List[int]: Current TDMA frame number Range: 0 to 2715647

  • Ber: List[float]: BER result (for mean BEP and signal quality mode) Range: 0 % to 100 %, Unit: %

# SCPI: FETCh:INTermediate:GSM:SIGNaling<Instance>:BER:CSWitched:MBEP
value: FetchStruct = driver.intermediate.ber.cswitched.mbep.fetch()

Returns the intermediate results of the BER CS measurement in mean BEP and signal quality mode. As indicated in the parameter descriptions below, each measure mode provides valid results for a subset of the parameters only. For the other parameters INV is returned. Results return as follows: <Reliability>, <NumberOfResults>, {<SegReliability>, <RXQualityFull>, <RXQualitySub>, <MeanBEP>, <CV_BEP>, <NumberOfBlocks>, <TDMA_FrameNr>, <BER>}segment 1, {…}seg. 2, …, {…}<NumberOfResults> For the details of measure modes and results, see ‘BER CS Measurement’.
