Dynamic range per capacitance (1.2.3)

  • Procedures : FmIltProc/DynamicRangeSpectro

  • Pre-test setup:
    • Note, that the related PTD contains a combined measurement of 1.2.3, 1.2.8 and 1.2.18 blocks, and cannot be applied in its original form.
    • Set the OGSE BB temperatures (SET_UP_OGSE_BB_TEMP_OBS, see the temperatures below)
