Test of a different cable for NE PCal laser driver

From 17h30 to 18h15 UTC, we worked on NE PCal, to test a cable to use the differential output of the fastDAC, instead of the single-ended output (and accordingly increase the gain of the channel sent to the fastDAC by a factor 2 in Acl:

ACL_SUM_CH        "noise_driving_pck"    ""    1    -1    noise_driving     0 Corr_RTPC

 

Looking at the data online, the noise with the differential output was a bit larger than when using the single-ended output, so we put back the setup in its initial configuration.

Some pictures and plots will be added later.

We will further test the differential vs single-ended driving on the setup at LAPP in the coming weeks.
