D4TG - Telemetry and Gamma Catridge for oil and gas open hole well logging tools
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 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.
