LO power level as output by box of Mellor:
19.23dBm with 20 dB attenuation on output making -0.77dBm714MHz stability measurements
A screenshot of scope data taken over ~6 hour period can be found here The yellow line shows the 714MHz signal as taken from the power supply room and the pink line shows the 357MHz signal as taken from the extraction kicker station.Clock stability investigation
The clock instability problem mentioned in the previous logbook entry has been narrowed down to the locking box. Specifically the cards labeled 1-5 in this diagram. More investigation is needed to pinpoint the exact cause of this instability.BPM readback channels
