The mine hosting the Laboratory has been divided into different branches. They contain different electronic circuit boards, which are connected via a parallel databus. Every card allows up to 8 multiplexed channels or two non-multiplexed channels. Every channel can be sampled at a different rate. Frequency counter cards.
Every card can record two channels at a different sampling rate.
The system can operate at a 10 Hz sampling rate. Tests will be done to evaluate whether this rate can be increased while maintaining a sufficient precision. The frequency counter module was tested in the Underground Laboratory of Walferdange for a few weeks. The 24 bit ADC module was tested also for a few months. The important drift is the instrument response to a new set up.
