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

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

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

  • Phase_Error_Rms: float: float Phase error RMS and peak value Range: 0 deg to 90 deg, Unit: deg

  • Phase_Error_Peak: float: float Phase error RMS and peak value Range: 0 deg to 90 deg, Unit: deg

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

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

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

fetch() → ResultData[source]
# SCPI: FETCh:GSM:MEASurement<Instance>:MEValuation:MODulation:SDEViation
value: ResultData = driver.multiEval.modulation.standardDev.fetch()

Returns the standard deviation of the single slot modulation results of the multi-evaluation measurement. The number to the left of each result parameter is provided for easy identification of the parameter position within the result array.

return

structure: for return value, see the help for ResultData structure arguments.

read() → ResultData[source]
# SCPI: READ:GSM:MEASurement<Instance>:MEValuation:MODulation:SDEViation
value: ResultData = driver.multiEval.modulation.standardDev.read()

Returns the standard deviation of the single slot modulation results of the multi-evaluation measurement. The number to the left of each result parameter is provided for easy identification of the parameter position within the result array.
