5-4-5-1 General Description
The MUX Board has 64 identical receive channels, and performs the following functions:
• Receiving the channels and connecting them to the BF Boards.
• Expanding the low/high channels in CW mode.
• TEE motion control.
• Monitoring temperature and voltage measurements via the I²C.
• FE Bus switch. To reduce the noise in the FE cards, the MUX switches off the FE Bus to the FB
during the data acquisition in CW mode.
• Min/max AC input monitoring, every ten seconds.
