fetch(preamble=Preamble.Default) → ResultData[source]
# FETCh:NRSub:MEASurement<Instance>:PRACh:MODulation:PREamble<Number>
value: ResultData = driver.nrSubMeas.prach.modulation.preamble.fetch(preamble = repcap.Preamble.Default)

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

Parameters:

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

Returns:

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

read(preamble=Preamble.Default) → ResultData[source]
# READ:NRSub:MEASurement<Instance>:PRACh:MODulation:PREamble<Number>
value: ResultData = driver.nrSubMeas.prach.modulation.preamble.read(preamble = repcap.Preamble.Default)

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

Parameters:

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

Returns:

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