Response structure. Fields:

  • Reliability: int: decimal ‘Reliability Indicator’ In list mode, a 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.

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

  • Statist_Expired: List[int]: decimal Number of measured steps Range: 0 to Statistical Length (integer value)

  • Slot_Info: List[enums.SlotInfo]: No parameter help available

  • Slot_Statistic: List[bool]: ON | OFF ON: Averaging over different burst type OFF: Uniform burst type in the averaging range

  • Out_Of_Tolerance: List[int]: decimal Percentage of measured bursts with failed limit check Range: 0 % to 100 %, Unit: %

  • Evm_Rms: List[float]: float Error vector magnitude RMS and peak value Range: 0 % to 50 %, Unit: %

  • Evm_Peak: List[float]: float Error vector magnitude RMS and peak value Range: 0 % to 50 %, Unit: %

  • Mag_Error_Rms: List[float]: float Magnitude error RMS and peak value Range: 0 % to 50 %, Unit: %

  • Mag_Error_Peak: List[float]: float Magnitude error RMS and peak value Range: 0 % to 50 %, Unit: %

  • Phase_Error_Rms: List[float]: No parameter help available

  • Phase_Error_Peak: List[float]: No parameter help available

  • Iq_Offset: List[float]: float I/Q origin offset Range: 0 dB to 50 dB, Unit: dB

  • Iq_Imbalance: List[float]: float I/Q imbalance Range: 0 dB to 50 dB, Unit: dB

  • Frequency_Error: List[float]: float Carrier frequency error Range: 0 Hz to 56000 Hz, Unit: Hz

  • Timing_Error: List[float]: float Transmit time error Range: 0 Symbol to 100 Symbol, Unit: Symbol

  • Burst_Power: List[float]: float Burst power Range: 0 dB to 71 dB, Unit: dB

  • Am_Pm_Delay: List[float]: float AM-PM delay (determined for 8PSK and 16-QAM modulation only - for GMSK zeros are returned) Range: 0 s to 0.9225E-6 s, Unit: s

# SCPI: FETCh:GSM:MEASurement<Instance>:MEValuation:LIST:MODulation:SDEViation
value: FetchStruct = driver.multiEval.listPy.modulation.standardDev.fetch()

Returns the standard deviation of the modulation results in list mode. The values listed below in curly brackets {} are returned for each measured segment: {…}seg 1, {…}seg 2, …, {…}seg n. The position of measured segments within the range of configured segments and their number n is determined by method RsCmwGsmMeas.Configure.MultiEval.ListPy.lrange.
