The table below compares

- between pairs of channels selected for a specific comparions in
https://web.pa.msu.edu/hep/atlas/l1calo/hub/testing/mgt_link_pairs_to_check.txt

- between measurements made with all 72 HTM Tramnsmitters enabled
and measurements made with just one HTM transmitter enabled.

This table includes

- all the channels identified in mgt_link_pairs_to_check.txt

- the 4 channels from each Hub with the lowest horizontal opening
found in the scans of all MGT channels

- one channel randomly selected for having a typical behavior
from the scans of all MGT channels



The entries in column #6 "All Sources" were from the sets of measurements
taken on 1-oct-2018
All were taken from Hub1 or Hub2 set "a" except
- the measurements with RandomRegTest comes from the Hub2 set "b"
- the measurements with FanOut Equalizer ON comes from the Hub2 set "c"

The entries in column #9 "Single butHTM6" were taken on 5-oct-2018 before
an operator error was discovered. All lanes from HTM06 were still active.
This set is incomplete and columns #9&10 are included for additional comparison.

The entries in column #7 "Single Lane" measurements were taken on 5-Oct-2018
(after discovering and correcting the HTM06 status) and 8-Oct-2018.
One exception: HUB1_HTM05_lane4 had been missed and taken on 9-Oct-2018.
During these measurement only one MGT Transmitter from one HTM was enabled.

The entries in column #8 are the differences between columns #7 and #9.
A postive number means that the eye diagram was open wider when
all other HTM MGT Transmitters were disabled.
