CONCLUSION
The CDBCAPTURE system is designed to
easily connect to most Crystal Semiconductor
ADC evaluation boards. Digital circuitry is
included on the evaluation boards to implement
a standard serial data bus. The CAPTURE board
is software reconfigurable to adjust for different
ADCs and future products. The CDBCAPTURE
system permits easy transfer of digital data to a
PC for analysis.
Many times it is desirable to collect data from
the ADC while it is operating inside a complete
acquisition system. In this case, the digital
interface circuitry for the CAPTURE board is
implemented outside the system on a modified
cable. The electrical system has to provide the
appropriate interconnect scheme, using either
connectors or test points to clip onto.
The modified serial cable allows the user to
measure performance of the ADC while it is
embedded in an electrical system. The ADC as
well as the system performance can be measured
and quantified. This information is used to
isolate problems and investigate how certain
subsystems interact with each other.
