Zach mentioned that all the existing post-processing software expects the data to be sampled at 1 kHz. Right now it's at 20 kHz, and it's causing problems.

Zach made an adult measurement with all four channels running.

=== Expanding the number of channels ===
=== Discrepancy between the expected and measured DAQ noise ===
It seems like the noise we are measuring is somewhat lower than what our bit depth suggests.
=== Adding an anti-aliasing filter to the polarimeter ===
In order to run the data acquisition at a smaller rate, we can place a hardware anti-aliasing filter on the differential polarimeter boards. This would take the computational load off the digital system and relax the requirements on how fast we acquire the data.
