H1 ISI CPS Sensor Noise Spectra Check - Weekly FAMIS 25991

Closes FAMIS 25991 last checked in alog 77785.

Things of note:

ETMY_ST1 has a notably different trace shape for channels, Y_ST1_CPSINF_V1, EY_ST1_CPSINF_V2, EY_ST1_CPSINF_V3:

  1. In the 1Hz-10Hz range, the more current reading has less noise
  2. In the 10-20Hz range, the more current reading has more noise in the form of both new and higher amplitude peaks.

Other than this, measurements look comparable to last week's check. PDF Attached.
