Channel Key
C = "Corner"
X = "X-END"
Y = "Y-END"
FO = "Fan Out"
MA = "MAster"

answer to slide 5 "Master Module" == Corner Station Timing Master
H1:SYS-TIMING_C_MA_A_PORT_2_SLAVE_CFC_TIMEDIFF_1
This above channel is the difference between
Corner Station Timing Distribution System (MCA / TDS) and Corner Station Timing Master
so this answers "What is the jitter (std? of a ~1 week time series?) for the Timing Master"
The offset is also interesting... isn't it?

H1:SYS-TIMING_C_MA_A_PORT_2_SLAVE_CFC_TIMEDIFF_2
This above channel is the difference between
Corner Station GPS NTP 1 PPS server (used as the reference for the atomic clock, and therefore the Timing Distribution System (MCA / TDS)) and Corner Station Timing Master

answer to slide 6 "Fanout Module" == End Station (and also Corner Station) Timing Fanout Modules (slaved to the master with a 1 PPS signal via optical fiber)
H1:SYS-TIMING_Y_FO_A_PORT_9_SLAVE_CFC_TIMEDIFF_1
Y end Time Code Converter (TCT) vs fanout
H1:SYS-TIMING_X_FO_A_PORT_9_SLAVE_CFC_TIMEDIFF_1
X end Time Code Converter (TCT) vs fanout
so this answers "What is the jitter (std? of ~1 week of time series?) between Timing Master and its fanout?" because end station TCTs are set by an atomic clock, and slaved to corner station (MCA / TDS), so they're the independent reference. But maybe the answer is jitter between (TDS / MCA) and Timing Master PLUS? MINUS? MULTIPLIED BY? (TCT) and Timing Fanout?

Also is it interesting to compar the two end stations fanout differences between the TCTs to each other?
compare H1:SYS-TIMING_Y_FO_A_PORT_9_SLAVE_CFC_TIMEDIFF_1 against H1:SYS-TIMING_X_FO_A_PORT_9_SLAVE_CFC_TIMEDIFF_1

The following is the pre-programmed delay (advance?) that the Timing Master puts on the 1 PPS signal that's sent to its fanouts:
H1:SYS-TIMING_C_MA_A_PORT_5_SLAVE_FANOUT_UPLINKDELAY
measure of the delay to corner station fanout A
H1:SYS-TIMING_C_MA_A_PORT_4_SLAVE_FANOUT_UPLINKDELAY
measure of the delay to corner station fanout B
H1:SYS-TIMING_C_MA_A_PORT_14_SLAVE_FANOUT_UPLINKDELAY
measure of the delay down to the X end (and back??)
H1:SYS-TIMING_C_MA_A_PORT_15_SLAVE_FANOUT_UPLINKDELAY
measure of the delay down to the Y end (and back??)
Not really answering any of Shiviraj's questions, but you would think the corner station delay would be small, and the end station delay would be L/c. They all say 29.8e-9 [s]. Why?



to answer slide 7, 
we need the endstation GPS receivers!

to answer slide 8
Read T0900050

to answer slide 9
switch on DAC to ADC feedback of duotone to important front ends
and trend

EX SUS Front End (h1susex) = H1:FEC-87_DUOTONE_TIME_DAC 
EY SUS Front End (h1susey) = H1:FEC-97_DUOTONE_TIME_DAC
OMC DCPD's Front End (h1lsc0) = H1:FEC-7_DUOTONE_TIME_DAC

32nd ADC channel on each front end is ADC DuoTone, e.g.
H1:IOP-SUS_EX_ADC_DT_OUT_DQ
H1:IOP-SUS_EY_ADC_DT_OUT_DQ
H1:IOP-LSC0_ADC_DT_OUT_DQ
31st ADC channel (if H1:FEC-97_DACDT_ENABLE button is ON) is DAC duotone, e.g.
H1:IOP-SUS_EX_DAC_DT_OUT_DQ
H1:IOP-SUS_EY_DAC_DT_OUT_DQ
H1:IOP-LSC0_DAC_DT_OUT_DQ
