with the difference that the measurement period in this one is stable at 1000000 μs. This
way an update rate of 1 point per second for the acquisition data is achieved, matching
the rate of the status data. We anticipate that the plots of the four graphs will be aligned in
the X axis during an online session. In the south point of the status tab, several settings
related to the graphs exist. These settings are similar to the ones in the online tab and refer
to the scaling, observation window and the shift window of the graphs. In the west of the
tab, several other components exist. They are in charge of plotting the values that appear
in the textboxes, the status of the power supplies as well as the status of the calibration
relays using state changing LEDs. Lastly, in the southeast and the west of the tab, other
status values like potentiometers and event counters subsist.
The second Hardware Information tab displays the remaining status elements. The default
view of this tab is shown in Figure 30.
The Hardware info tab contains several components like textboxes, LEDs, labels and
graphs. Most of the elements are mainly information about the status of the two small form-
factor pluggable transceivers (SFPs) on the BLEDP card used for the communication of
the card with the network, as well as other hardware information such as firmware version,
chip ID and global address. The same update rate of 1 Hz for the plots and the other
information applies here as well
