# FETCh:NRSub:MEASurement<Instance>:MEValuation[:CC<no>][:LAYer<layer>]:DMARker<Nr>:PERRor
value: float = driver.nrSubMeas.multiEval.cc.layer.dmarker.perror.fetch(xvalue = 1, trace_select = enums.TraceSelect.AVERage, carrierComponent = repcap.CarrierComponent.Default, layer = repcap.Layer.Default, deltaMarker = repcap.DeltaMarker.Default)

Uses the markers 1 and 2 with relative values on the diagrams: EVM RMS, EVM peak, magnitude error and phase error vs OFDM symbol.

Suppressed linked return values: reliability

Parameters:

  • xvalue – X-value of the marker position relative to the x-value of the reference marker There are two x-values per OFDM symbol on the x-axis (symbol 0 low, symbol 0 high, …, symbol 14 low, symbol 14 high) .

  • trace_select – CURRent | AVERage | MAXimum

  • carrierComponent – optional repeated capability selector. Default value: Nr1 (settable in the interface ‘Cc’)

  • layer – optional repeated capability selector. Default value: Nr1 (settable in the interface ‘Layer’)

  • deltaMarker – optional repeated capability selector. Default value: Nr1 (settable in the interface ‘Dmarker’)

Returns:

yvalue: Y-value of the marker position relative to the y-value of the reference marker
