keyword=fast raster woes
Upon my casual remarrk that the "beam" screen in the online kumac looks
goofy, Joerg investigated and discovered that the raster information was
not going into the data stream properly. The raster signals going into
the adc's need to have a negative offset to be properly read out. Joerg
dicovered that the frx signal was centered on 0.0, and the fry signal had
a large positive offset. This seems weird since we were reading out the
raster properly as recently as January - so the wiring must have changed
somehow.
Anyway - Joerg is currently trying to pick off some signals we can get
into the data stream and use.
NOte that the above implies we have no raster information for any of the
CH2 running so far.
