I realize this forum is more for connecting up a 555 chip but I thought maybe there is some advanced engineer out there somewhere looking. I have a very expensive line scan CCD sensor from a spectrometer that I would like to get operating. The sensor has zero markings on it so I think it is proprietary. However, there are only 3 wires to it, aside from the power supplies and output signal so it seems like it would be easy to figure out how to drive it.
The picture shows the traced out circuit of the driver. I have a pulse generator connected to the clock pin and a second pulse generator to the base of the transistor. The waveforms on the driver chip are nice and clean and the waveform on the collector of the transistor is clean. (note that this is the original driver board from the spectrometer) The problem is that the CCD output changes for all of the pixels at once! There doesn't seem to be any shifting going on. Covering part of the sensor causes all of the output pixels to change instead of only the ones being covered. I have varied both generators over wide ranges to see if there was some critical relationship but have so far not been able to see any separate changes in the output pixels. Am I overlooking something here?
