Spectroscopy Setup
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)
- Move filter wheel to "POS A" (SPEC_fltw_move)
CUS scripts: SPEC_dyn_range_obs, SPEC_DiagHK_DynRange_block_stop, SPEC_DiagHK_DynRange_block_start
- Each measurement block (OGSE BB temperature setup) runs through all combinations of integration capacitor (0.1pF, 0.3pF, 1pF, 3pF) and reset interval values (1/8s, 1/4s, 1/2s, 2s), and is performed for two grating positions (GR-1 = 760000 and GR-2 = 490000).

Signal dependence on chopper frequency (1.2.8)
Procedures : FmIltProc/DynamicRangeSpectro
- Pre-test setup:
