Waveforms

Waveforms have been saved as b(string#)_(OM#).gif, where 'b' means 'before' the SWAMP exchange. Waveforms taken afterwards are denoted a(string#)_(OM#).gif, where 'a' means 'after'. The oscilloscope settings were 500 ns/div and 50 mV/div.

After the upgrade we recorded waveforms for a longer time scale (2 us) for random channels in each strings.
