David | Current status | Michael is modifying the settings of the electron cooler --> changed beam from bunched to coasting
Merger, Tape server (WS3) checks: DONE, writing ~1036 kB/s, refreshing is fine
Leakage current (WS4): 3.46 uA , stable current
DAQ (WS2): temperature checked,
- clock status:
Clock status test result: Passed 5, Failed 0
Understand status as follows
Status bit 3 : firmware PLL that creates clocks from external clock not locked
Status bit 2 : always logic '1'
Status bit 1 : LMK3200(2) PLL and clock distribution chip not locked to external clock
Status bit 0 : LMK3200(1) PLL and clock distribution chip not locked to external clock
If all these bits are not set then the operation of the firmware is unreliable
- adc calibration:
Calibration test result: Passed 5, Failed 0
If any modules fail calibration , check the clock status and open the FADC Align and Control browser page to rerun calibration for that module
- white rabbit check:
Base Current Difference
aida01 fault 0xc228 : 0xc274 : 76
aida02 fault 0x5e98 : 0x5ee0 : 72
aida03 fault 0x92d3 : 0x931f : 76
aida04 fault 0x7a92 : 0x7ade : 76
aida05 fault 0xedc0 : 0xedcc : 12
White Rabbit error counter test result: Passed 0, Failed 5
Understand the status reports as follows:-
Status bit 3 : White Rabbit decoder detected an error in the received data
Status bit 2 : Firmware registered WR error, no reload of Timestamp
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR
DAQ (WS2): everything ok
Online monitoring (WS 5): done; |
