Accelerometer 4 status

Odd behavior compared to other accelerometers

• Plots from Kim (23-Jun-2008)
  • Note the event around the 6th tick on the x-axis where the blue trace in accel4 moves but does not in accel 1. This event is shown in detail in the 5th and 6th plots.

• accelerometer 1:
  

• accelerometer 2:
  

• accelerometer 3:
  

• accel1 (blue) & accel4 (red) x-channel comparison:
  

• accel1 (blue) & accel4 (red) y-channel comparison:
  

• power spectra of accel1 (green) and accel4 (red):
