Tune Fitting Graphs

Tune Fitting Graphs


This screen shows three views of the tune fit analysed on Tune Fitting Overview.  The prefix to all the PVs is described on that page.  Here we see the following graphs:

TitlePVDescription
Magnitude of Response:TUNE:DMAGNITUDEMagnitude of the raw signal (in blue).

:TUNE:MMAGNITUDEMagnitude of the fitted model (in red).
Phase of Response:TUNE:DPHASEPhase of the raw signal (in blue).

:TUNE:MPHASEPhase of the fitted model (in red).
I/Q:TUNE:I, :TUNE:QRaw swept spectral data in I/Q format (in blue).

:TUNE:MI, :TUNE:MQFitted model in I/Q format (in red).

Here we see the residue from fitting:

TitlePVDescription
Fit Residue:TUNE:RESIDUEThis graph shows the power spectrum of the difference between the fitted model and the raw swept spectrum.
