Requirement:
The DAQ system will be capable of performing the following operations on the
10-bit SVT data stream:
-
Subbtraction of a programmable, per channel, per time bucket offset of up to
8 bits in magnitude
-
Per channel, programmable compression of each time bucket 10-bit ADC value
into an 8-bit quantity
-
Programmable zero suppression of time bucket data that fall outside of
programmable threshold, pre, and post hit criteria
These correction will all be performed in real time with no adverse affect on
the data rates referred to in the triggering requirements section.
Justification:
These operations are required for reducing the magnitude of the event data
early in the acquisition cycle. These reductions are necessary to meet data
archiving performance requirements later in the system.
