• Iphase: List[float]: Normalized I amplitude

• Qphase: List[float]: Normalized Q amplitude

# SCPI: FETCh:LTE:MEASurement<Instance>:PRACh:TRACe:IQ
value: FetchStruct = driver.lteMeas.prach.trace.iq.fetch()

Returns the results in the I/Q constellation diagram. There is one pair of values per modulation symbol. For preamble format 4, there are 139 symbols. For preamble format 0 to 3, there are 839 symbols. 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.
