abort() → None[source]

# SCPI: ABORt:WCDMa:SIGNaling<instance>:ERGCh
driver.ergch.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[source]

# SCPI: ABORt:WCDMa:SIGNaling<instance>:ERGCh
driver.ergch.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.

fetch() → ResultData[source]

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

Return all single value results of the E-RGCH measurement. ‘Missed Up’, ‘Missed Down’ and ‘Missed Hold’ test refers to wizard settings, see ‘Using the WCDMA Wizards’. 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.

initiate() → None[source]

# SCPI: INITiate:WCDMa:SIGNaling<instance>:ERGCh
driver.ergch.initiate()


    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.

initiate_with_opc() → None[source]

# SCPI: INITiate:WCDMa:SIGNaling<instance>:ERGCh
driver.ergch.initiate_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.

read() → ResultData[source]

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

Return all single value results of the E-RGCH measurement. ‘Missed Up’, ‘Missed Down’ and ‘Missed Hold’ test refers to wizard settings, see ‘Using the WCDMA Wizards’. The number to the left of each result parameter is provided for easy identification of the parameter position within the result array.

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

stop() → None[source]

# SCPI: STOP:WCDMa:SIGNaling<instance>:ERGCh
driver.ergch.stop()


    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.

stop_with_opc() → None[source]

# SCPI: STOP:WCDMa:SIGNaling<instance>:ERGCh
driver.ergch.stop_with_opc()


    INTRO_CMD_HELP: Starts, stops, or aborts the measurement:

    - INITiate... starts or restarts the measurement. The measurement enters the 'RUN' state.
