Title | PV | Description |
---|---|---|
Source | :DET:SELECT_S | Normally the data to each detector should be passed through the FIR, if only to reject the bunch by bunch fill pattern, but it is possible to select the raw ADC data as an alternate source. |
FIR delay | :DET:FIR_DELAY_S | This should can be set to the group delay of the FIR group delay. For an N tap filter, this should normally be set to (N+1)/2filter so that this delay is compensated for in the detector. However, we have discovered at DLS that setting this to anything other than 0 is confusing. |
Captured | :DET:SAMPLES | This records the number of samples captured in the last sweep. |
Underrun | :DET:UNDERRUN | This should never indicate anything other than "Ok", an error here indicates a worrying internal FPGA problem, or possibly an unreasonably small bunch count. |
Waveforms | :DET:FILL_WAVEFORM_S | This is a fudge to help EDM, and should otherwise be set to "Truncated". This will probably be deleted. |
