1-to-8 Pulse and Frequency Distribution Amplifier

S/N005 assembled and tested

Amplifier S/N 005 was assembled and tested, housing PDA2017.07 and FDA2017.07 boards.
Initial phase-noise tests show good performance, similar to the previous generation of the board.
The new PDA2017.07 design using IDT5PB1108 has very fast rise-time (to be measured), possibly a quite low output-impedance (to be fixed?) and a preliminary channel-to-channel output skew of max 250 ps.

18-04-17: clean that fibre and SFP!

The White Rabbit team at CERN organised a short course about fibre-optic cleaning and inspection*.

A special fibre inspection microscope that automatically analyses the image to decide if a cable or SFP passes or fails the norms was demonstrated.
The images of some of the often-used cables and SFP modules that we picked from the development lab, showed clearly traces of grease and dust.

Tutorial at ICALEPCS conference in October

The ICALEPCS organizing committee will organize a pre-conference workshop on WR in Barcelona in October.

We intend to make this more of a “WR tutorial.” and we think there will be something to learn and discuss for everybody: newcomers, casual users and even experts.
