Dedicated electronics and data acquisition has been developed for the stand-alone test programme.
For the demonstrator, analog and digital data transmission schemes are both being studied. For the first structure that will be deployed and connected to an electro-optical cable, we plan to use an analog transmission. Its intrinsic robustness makes it easy to implement and suited to our short term needs. However, we have reached the conclusion that only a digital data transmission can meet our requirements for a km-scale detector.
