FerfCh commands group definition. 5 total commands, 2 Sub-groups, 3 group commands

class CalculateStruct[source]

Response structure. Fields:

  • Reliability: int: See ‘Reliability Indicator’

  • Ferf_Ch: float: Forward link frame error rate Queries the percentage of the frame error rate over the total number of received frames for FCH. Range: 0 % to 100 %, Unit: %

  • Confidence_Level: float: Measured confidence level Queries the statistical probability that the true FER is within limits based on the current number of frame errors compared to the number of frames received. Range: 0 % to 100 %, Unit: %

  • Frame_Errors: float: Total number of detected frame errors. Range: 0 to 100E+3

  • Frames: float: Total number of test frames sent. Range: 0 to 100E+3

  • Erased_Frames: int: Total number of erased frames (counted as errored frames) . Not all errored frames are erased. Some can be undetected by the MS. Range: 0 to 100E+3

class ResultData[source]

calculate() → CalculateStruct[source]
# SCPI: CALCulate:CDMA:SIGNaling<Instance>:RXQuality:FERFch
value: CalculateStruct = driver.rxQuality.ferfCh.calculate()

Returns the results of the forward link FER measurement, see ‘FER FCH / FER SCH0 View (Tab) ‘. The values described below are returned by FETCh and READ commands. CALCulate commands return limit check results instead, one value for each result listed below.

return

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

fetch() → ResultData[source]
# SCPI: FETCh:CDMA:SIGNaling<Instance>:RXQuality:FERFch
value: ResultData = driver.rxQuality.ferfCh.fetch()

Returns the results of the forward link FER measurement, see ‘FER FCH / FER SCH0 View (Tab) ‘. The values described below are returned by FETCh and READ commands. CALCulate commands return limit check results instead, one value for each result listed below.

read() → ResultData[source]
# SCPI: READ:CDMA:SIGNaling<Instance>:RXQuality:FERFch
value: ResultData = driver.rxQuality.ferfCh.read()

Returns the results of the forward link FER measurement, see ‘FER FCH / FER SCH0 View (Tab) ‘. The values described below are returned by FETCh and READ commands. CALCulate commands return limit check results instead, one value for each result listed below.
