MIPS_045a Bias Commanding


IOC-MIPS_045a     10200C        
Title:   Bias Level Commanding     This can probably go away, since it overlaps with bias/sensitivity tests    
               
Objective:   To measure detector response to changing bias levels.          
               
Description:   This test should really measure how the detector sensitivity, stability, and noise properties          
    respond to different bias levels in the presense of cosmic rays.          
    As such, it will probably end up being done as part of another series of tests          
    (for sensitivity, for example) that need to be done anyway.          
               
Place in Schedule:   The telescope must be cold enough for the germanium arrays to work,          
    but it can probably be done at the background level appropriate for initial standard star measurements.          
               
Required Conditions:              
               
Resources:              
  duration (best estimate)     I'll bookkeep this test with the sensitivity tests, so no time required here.      
  real time downlink (Y / N)     n      
  special post event actions (Y / N)     The data must be analyzed.      
               
Outcome:              
  description            
  can proceed in parallel with other activity            
  must outcome be confirmed before next event / test /activity            
  method of confirmation (sensor TLM, data analysis, etc.)            
  estimate of data turn around if required for confirmation            
               
Unique or included in planned uplink or downlink/analysis tool         Can execute planned AOTs with different bias levels.    
               
Contingency Plan:              
"What if..."
