Dynamic range per capacitance

• Procedures : FmIltProc/DynamicRangeSpectro

• Pre-test setup:
  • 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

• Below are all combinations of the OGBE BB temperature, integration capacitor and reset interval values. Note, that the parameter of the SPEC_dynamic_range_fmilt123_OBS CUS script is the ramp length, and not the reset interval! (1/16s -> 16; 1/4s -> 64; 1/2s -> 128; 2s -> 512). The integration capacitor/reset interval block is performed for two grating positions: GR-1 = 760000 and GR-2 = 490000.
