CHEMS Deflection Voltage Stepping

 

16 DVPS (Deflection Voltage Power Supply) steps out of 32 available

 

1 energy spectrum per sector (86.25 s for nomimal Pspin)
i.e., 1 step per subsector (5.391 s for nominal Pspin)

 

CHEMS Science (or Matrix) Rates

 

34 science rates (16 bits --> 8 bits log compressed each)
(some of these rates are separately accumulated for each of the 3 elevation sectors)
transmitted once per DVPS step (5.391 s for nominal Pspin)
:
50.5 bits/s

 

CHEMS Accumulator Rates

 

17 accumulators (24 bits --> log compressed each)
transmitted once per DVPS step (5.391 s for nominal Pspin)
:
37.8 bits/s
