abort() → None

# SCPI: ABORt:WCDMa:SIGNaling<instance>:BER
driver.ber.abort()


    INTRO_CMD_HELP: Starts, stops, or aborts the measurement:

    - INITiate... starts or restarts the measurement. The measurement enters the 'RUN' state.
    - STOP... halts the measurement immediately. The measurement enters the 'RDY' state. Measurement results are kept. The resources remain allocated to the measurement.
    - ABORt... halts the measurement immediately. The measurement enters the 'OFF' state. All measurement values are set to NAV. Allocated resources are released.

Use FETCh…STATe? to query the current measurement state.

abort_with_opc() → None

# SCPI: ABORt:WCDMa:SIGNaling<instance>:BER
driver.ber.abort_with_opc()


    INTRO_CMD_HELP: Starts, stops, or aborts the measurement:

    - INITiate... starts or restarts the measurement. The measurement enters the 'RUN' state.
    - STOP... halts the measurement immediately. The measurement enters the 'RDY' state. Measurement results are kept. The resources remain allocated to the measurement.
    - ABORt... halts the measurement immediately. The measurement enters the 'OFF' state. All measurement values are set to NAV. Allocated resources are released.

Use FETCh…STATe? to query the current measurement state.

Same as abort, but waits for the operation to complete before continuing further. Use the RsCmwWcdmaSig.utilities.opc_timeout_set() to set the timeout value.

calculate() → CalculateStruct

# SCPI: CALCulate:WCDMa:SIGNaling<instance>:BER
value: CalculateStruct = driver.ber.calculate()

Returns all results of the signaling BER measurement. 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. 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 CalculateStruct structure arguments.

fetch() → ResultData

# SCPI: FETCh:WCDMa:SIGNaling<instance>:BER
value: ResultData = driver.ber.fetch()

Returns all results of the signaling BER measurement. 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. The number to the left of each result parameter is provided for easy identification of the parameter position within the result array.

initiate() → None

# SCPI: INITiate:WCDMa:SIGNaling<instance>:BER

    INTRO_CMD_HELP: Starts, stops, or aborts the measurement:

    - INITiate... starts or restarts the measurement. The measurement enters the 'RUN' state.
    - STOP... halts the measurement immediately. The measurement enters the 'RDY' state. Measurement results are kept. The resources remain allocated to the measurement.
    - ABORt... halts the measurement immediately. The measurement enters the 'OFF' state. All measurement values are set to NAV. Allocated resources are released.

read() → ResultData

# SCPI: READ:WCDMa:SIGNaling<instance>:BER
value: ResultData = driver.ber.read()
