Changes

'''Week 3''' - The fuses came in. I had time to quickly test that the power supply was still functional. I replaced the fuse, and the power supply's "Power" light turned on. I was also given a set of cables used specifically for the active collimator.

'''Week 4''' - – I connected the collimator to the amplifiers to the oscilloscope for testing today. I believe that I had the correct setup, but the power supply did not turn on again. I tried unplugging the power supply from the setup and testing a fresh fuse. The “Power” light went on for a few seconds, and then dimmed out.  I used an ohmmeter o verify that the other remaining fuses were working. Brendan helped me with examining the interior of the power supply for possible issues. Once we tried a third fuse, the power supply worked. I then connected the collimator to the oscilloscope and used my finger to test each pin cushion; I received a signal from each one.

After collecting the compact flash card from Brendan, I started taking pictures of waveforms from the oscilloscope. Professor Jones has instructed me to set a threshold, wait for the oscilloscope to request a trigger, and then tap the screw connected to the pin cushion in order to create a snapshot on the oscilloscope. I spent more time reading the oscilloscope manual to ensure that I understand the terminology and the full functionality of the oscilloscope.
