 ====Accomplishments====
-  - Sytem configuration refined and working as diagramed. See the NSG Configuration diagram below.
+  - System configuration refined and working as diagramed. See the NSG Configuration diagram below.
   - 16 feed pols hooked up to the RF switched. Verified the switch is working.
   - 200MHz filter from all the RFCB outputs removed. Now have 600MHz coming out out the RFCB

   - Two SNAPS hooked up and working. Running through system tests now.
   - Figured out where to measure and debug the Feeds and signal chain. See the Signal Measurements Diagram below.
-  - A test run of the SNAP all night, all feeds hooked up to the RF switch 1GHz to 10BHz, source: 3c295.
+  - A test run of the SNAP all night, all feeds hooked up to the RF switch 1GHz to 10BHz, source: 3c295. Turns out the results were not that great because the signal levels in some cases were too strong for the SNAP. Jack and JonR are working to compensate.
   - Spectrum Analyzer testing. The 9kHz->3G scope could see Casa@1420, but could NOT see w3oh@6667. The other 2 scopes could see w3oh clearly.
   - On the SA we were able to clearly see an 8MHz comb from 1 to 2GHz. We will be investigating. See pic below.
