FUNCTIONAPPLICATIONSTRUCTURAL COMPOSITIONtSPECIFICATIONS
It
receives the command download by the surface system, then transmit this command
to the logging tools after decoding. It
also can code and amplify the data from the logging tools and upload it to the
surface system. Meantime, multiple analog could be acquired.
It’s the data transmission sub of
HALIBURTON DITS tool.
It
mainly consists of photomultiplier and more circuit boards. And the circuit
boards included high voltage board,
pre-amplifier board, power panel, emission/receiver board, analog board,
BCU board etc.
