Electronics - wiring diagrams and parts list

NOTES The complete wiring diagram for the PAR is available on the website: http://chile1.physics.upenn.edu/GBT. Username : GBTPassword : greenbank Selected parts are included in this document. It is important to ensure that power to the analog electronics tower is turned on after the digital electronicsTo do this hold up capacitors delay the power-up of the Vicor supplies by different amounts.
