class PrachCls[source]

Prach commands group definition. 36 total commands, 6 Subgroups, 10 group commands

get_mo_exception() → bool[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:MOEXception
value: bool = driver.configure.lteMeas.prach.get_mo_exception()

Specifies whether measurement results that the CMX500 identifies as faulty or inaccurate are rejected.

return:

meas_on_exception: OFF: Faulty results are rejected. ON: Results are never rejected.

get_no_preambles() → int[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:NOPReambles
value: int = driver.configure.lteMeas.prach.get_no_preambles()

Specifies the number of preambles to be captured per measurement interval.

return:

number_preamble: No help available

get_pc_index() → int[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:PCINdex
value: int = driver.configure.lteMeas.prach.get_pc_index()

The PRACH configuration index identifies the PRACH configuration used by the UE (preamble format, which resources in the time domain are allowed for transmission of preambles etc.) . For Signal Path = Network, use[CONFigure:]SIGNaling:LTE:CELL:POWer:UL:CINDex.

return:

prach_conf_index: No help available

get_pformat() → int[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:PFORmat
value: int = driver.configure.lteMeas.prach.get_pformat()

No command help available

return:

preamble_format: No help available

get_po_preambles() → PeriodPreamble[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:POPReambles
value: enums.PeriodPreamble = driver.configure.lteMeas.prach.get_po_preambles()

Specifies the periodicity of preambles to be captured for multi-preamble result views.

return:

period_preamble: MS05: 5 ms MS10: 10 ms MS20: 20 ms

get_repetition() → Repeat[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:REPetition
value: enums.Repeat = driver.configure.lteMeas.prach.get_repetition()

Specifies the repetition mode of the measurement. The repetition mode specifies whether the measurement is stopped after a single shot or repeated continuously. Use CONFigure:..:MEAS<i>:…:SCOunt to determine the number of measurement intervals per single shot.

return:

repetition: SINGleshot: Single-shot measurement CONTinuous: Continuous measurement

get_scondition() → StopCondition[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:SCONdition
value: enums.StopCondition = driver.configure.lteMeas.prach.get_scondition()

Qualifies whether the measurement is stopped after a failed limit check or continued. SLFail means that the measurement is stopped and reaches the RDY state when one of the results exceeds the limits.

return:

stop_condition: NONE: Continue measurement irrespective of the limit check. SLFail: Stop measurement on limit failure.

get_ssymbol() → int[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:SSYMbol
value: int = driver.configure.lteMeas.prach.get_ssymbol()

Selects the OFDM symbol to be evaluated for single-symbol modulation result diagrams. The number of OFDM symbols in the preamble (<no of symbols>) depends on the preamble format, see Table ‘Preambles in the time domain’.

return:

selected_symbol: No help available

get_timeout() → float[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:TOUT
value: float = driver.configure.lteMeas.prach.get_timeout()

Defines a timeout for the measurement. The timer is started when the measurement is initiated via a READ or INIT command. It is not started if the measurement is initiated manually. When the measurement has completed the first measurement cycle (first single shot) , the statistical depth is reached and the timer is reset. If the first measurement cycle has not been completed when the timer expires, the measurement is stopped. The measurement state changes to RDY. The reliability indicator is set to 1, indicating that a measurement timeout occurred. Still running READ, FETCh or CALCulate commands are completed, returning the available results. At least for some results, there are no values at all or the statistical depth has not been reached. A timeout of 0 s corresponds to an infinite measurement timeout.

return:

timeout: No help available

get_view() → ViewPrach[source]

# SCPI: CONFigure:LTE:MEASurement<Instance>:PRACh:VIEW
value: enums.ViewPrach = driver.configure.lteMeas.prach.get_view()
