fetch(preamble=Preamble.Default) → ResultData[source]

FETCh:LTE:MEASurement<Instance>:PRACh:MODulation:PREamble<Number>

Snippet: value: ResultData = driver.prach.modulation.preamble.fetch(preamble = repcap.Preamble.Default)

Return the single value results of the ‘EVM vs Preamble’ and ‘Power vs Preamble’ views, for a selected preamble. See also ‘View EVM vs Preamble, Power vs Preamble’.

param preamble:

optional repeated capability selector. Default value: Nr1 (settable in the interface ‘Preamble’)

return:

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