DIY Atomic Clock mini rack

I can finally compare how accurate my clocks are against an atomic reference! At least in one dimension. The timing rabbit hole goes deep... this is step 2 on about a 10,000 step journey :) Some of the things I mentioned (some links are affiliate links): - NetTimeLogic PPS Analyzer: https://www.nettimelogic.com/tools-pps-analyzer.php - Switchberry: https://github.com/Time-Appliances-Project/Switchberry - N150 Mini PC: https://amzn.to/4wH8OhV - Time Stick: https://github.com/Time-Appliances-Project/TimeStick - JetKVM: https://jetkvm.com - JetKVM PoE Adapter: https://wisdpi.com/products/jet-poe-splitter - JetKVM 3D printed rackmount: https://makerworld.com/en/models/2139891-sg105-sg1005p-jetkvm-left-mounted-10-rack-mount?from=search - Calnex Rb/GPS Timing Reference: https://calnexsol.com/datasheet/rb-gps-reference-source/ - Meinberg microSync XS: https://www.meinberg-usa.com/products/microsync-series.htm - GPS Source 4-way splitter: https://www.gpssource.com/collections/splitters/products/s14wi-gps-1x4-wireless-splitter - Netgear GS305P 4-port PoE Switch: https://amzn.to/4nCL1LK - Tupavco 10" Rack PDU 4 outlet: https://amzn.to/4tMSaum - RackMate T2 12U mini rack: https://amzn.to/49hSGcG - Various BNC to SMA cables: https://amzn.to/4dSHcil Huge thanks to NetTimeLogic, Meinberg, and the Time Appliances Project for assistance with this setup!
