class IqCls[source]

Iq commands group definition. 1 total commands, 0 Subgroups, 1 group commands

class FetchStruct[source]

Response structure. Fields:

  • Reliability: int: ‘Reliability indicator’

  • Iphase: List[float]: Normalized I amplitude

  • Qphase: List[float]: Normalized Q amplitude

fetch() → FetchStruct[source]
# SCPI: FETCh:NRSub:MEASurement<Instance>:PRACh:TRACe:IQ
value: FetchStruct = driver.nrSubMeas.prach.trace.iq.fetch()

Returns the results in the I/Q constellation diagram. There is one pair of values per modulation symbol. The number of modulation symbols equals the number of subcarriers and depends on the preamble format. The results are returned in the following order: <Reliability>, {<IPhase>, <QPhase>}symbol 1, …, {<IPhase>, <QPhase>}symbol n See also ‘Square I/Q Constellation’.

return:

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