Table of Contents
Decode Module Readout using Oscilloscope
Setup
Setup module as described here and connect corresponding POH fiber to scope: Module Readout
Save waveform
Use 50 or 100 ns per divisions (not enough points with 200ns) On the scope: Go to “Utilities” → “Disk Utilities” Go to “Save waveform” tab. Chose scope channel where POH fiber is connected Save in format “ASCII” with deliminator “Comma”
Decode waveform
Use Wolfram's script to decode waveform:
cd tbmdecoder $ python getwfm.py -file wfm-345-2.isf -raw reading wfm-345-2.isf sdata1 A: 7fc03b17f87f87f87f87f87f87f87f87fe2200 sdata1 B: 7fc03b17f87f87f87f87f87f87f87f87fe2200 $ python getwfm.py -file wfm-345-2.isf reading wfm-345-2.isf sdata1, A channel: 7fc TBM header 0x03b1 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7fe TBM trailer 0x2200 sdata1, B channel: 7fc TBM header 0x03b1 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7f8 ROC header 7fe TBM trailer 0x2200
