== 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). 

  * Setup #1: OBSE BB1: 16.3K, OGSE BB2: 15.7K

  * Setup #2: OBSE BB1: 18.8K, OGSE BB2: 18.2K

  * Setup #3: OBSE BB1: 25.4K, OGSE BB2: 24.6K

  * Setup #4: OBSE BB1: 32.5K, OGSE BB2: 31.5K

  * Setup #5: OBSE BB1: 40.7K, OGSE BB2: 39.3K

  * Setup #6: OBSE BB1: 48.0K, OGSE BB2: 46.0K

  * Setup #7: OBSE BB1: 61.4K, OGSE BB2: 58.6K

  * Setup #8: OBSE BB1: 77.0K, OGSE BB2: 73.0K
 
 * Estimated duration of the tests for each indivitual OGSE BB setting: 2x4x4x128s + 2x15s for grating movement + 1080s OGSE BB stabilization =  1.45h  

== Signal dependence on chopper frequency (1.2.8) ==
 
 * Procedures : FmIltProc/DynamicRangeSpectro
 * Pre-test setup:
   * CS1 temperature: 70.5K (fixed)
   * CS2 temperature: 76.0K (fixed)
   * Grating: 425250 (fixed)
   * Reset interval: 1/4s (fixed)
   * SPU setup: Entire slope fitting
   * Set the OGSE BB1 temperature (SET_UP_OGSE_BB_TEMP_OBS, see the temperatures below)
   * Move filter wheel to "POS B" (SPEC_fltw_move)
 * CUS script: SPEC_chopper_freq_fmilt128_obs

 * Each measurement block (OGSE BB temperature setup) performs a tringular chopping measurement between the calibration sources and the OGSE BB1 as OGSE BB1 --> CS1 --> OGSE BB1 --> CS2 --> OBSE BB1 --> CS1 --> ... 

  * Setup #1: OBSE BB1: 18.8K

  * Setup #2: OBSE BB1: 25.4K

  * Setup #3: OBSE BB1: 32.5K

  * Setup #4: OBSE BB1: 40.7K

  * Setup #5: OBSE BB1: 48.0K

  * Setup #6: OBSE BB1: 61.4K ?

  * Setup #7: OBSE BB1: 77.0K ?
 
 * Estimated duration of the tests for each indivitual OGSE BB setting: ~0.45h

== Time constants: flux changes, spectrometer (1.2.18) ==
 
 * Procedures : FmIltProc/DynamicRangeSpectro
 * Pre-test setup:
   * Grating: 425250 (fixed)
   * Reset interval: 1/4s (fixed)
   * Integration capacitor: should be adjusted according to 1.2.3
   * SPU setup: Entire slope fitting
   * Set the OGSE BB1 temperature (SET_UP_OGSE_BB_TEMP_OBS, see the temperatures below)
   * Move filter wheel to "POS B" (SPEC_fltw_move)
   * Move chopper to CFOV
 * CUS script: SPEC_time_constant_fmilt1218_obs
 * Each measurement block (OGSE BB temperature setup) performs the following measurement: the detector is staring at the OGSE BB1 source, and the filter wheel is rotated back and forth.  

  * Setup #1: OBSE BB1: 18.8K

  * Setup #2: OBSE BB1: 25.4K

  * Setup #3: OBSE BB1: 32.5K

  * Setup #4: OBSE BB1: 40.7K

  * Setup #5: OBSE BB1: 48.0K

  * Setup #6: OBSE BB1: 61.4K ?

  * Setup #7: OBSE BB1: 77.0K ?
 
 * Estimated duration of the tests for each indivitual OGSE BB setting: ~0.25h, without OGSE BB stabilization.
