    keyword=Amplifier and attenuator in for HAPPEX BCM cavities parasitic test

    I put inline a 30 db attenuator and the amplifiers for the HAPPEX DAQ to be able to study signal over background even when the experiment is running at 4 uA. That should give a signal similar to a few hundreds of nanoamps.

    I moved also the upstream BCM cable to BPM X position since the BCM DAC seems both dead.

    Trent will load a firwmare to send the BCM signal there.
