Six Way Concatenator
from Geomatrix
The Geomatrix Earth Science Ltd Six Way Concatenator has been specifically designed to enhance the functionality of the Geometrics G-823, 862, 880 & 882 magnetometers. The Geomatrix Six Way Concatenator offers a reliable, easy to use, solution for managing sophisticated Geometrics caesium sensor arrays.
Initially developed for English Heritage, the small light weight package is perfectly suited for deployment on hand carts or vehicle towed systems. By utilising the GPS Pulse Per Second (PPS) to synchronise the trigger timing it is possible to accurately account for variable latency within the data acquisition software at high sample rates.
Features
- Able to concatenate 6 Geometrics caesium magnetometers & GPS sentence.
- Two modes of operation: Continuous & Trigger .
- Trigger Timing synchronised to GPS PPS pulse enabling PC latency correction at fast sample rates.
- High sampling speeds which reject 50&60Hz mains noise.
- Incorporate magnetometer ID into concatenated sentence, aiding system troubleshooting.
- Channel bypass switches.
- Power feed through to all instruments.
- Data telemetry compatible with existing software (Geometrics MagLog & Geomar Nav823 software)
