data handling and viewing. We have to note here that the SFP2 graph and the cor-
responding components in Figure 35 remain inactive, because the connection in this
case was achieved through the Ethernet SFP (SFP1). The optical fiber SFP (SFP2)
was not even connected to the system during this acquisition.
Accordingly, we can examine Figures 36 and 37 which represent a multi-channel
acquisition from the same system in the PS facility. We exclude the figure with the
Hardware Info status tab, because it is identical to the single-channel transmission.
Figure 36 shows the online display during a multi-channel acquisition. Every aver-
aged data plot corresponds to a specific channel. In this example, only three detec-
tors are connected with the input of every channel, so the other channels produce
simply a stable trace or noise. In this mode, a user is able to hide or reveal channel
plots at will. The channel checkboxes are used for that purpose.
Likewise, Figure 37 indicates the first status tab in the multi-channel acquisition. The
only difference from the single-channel mode is that the first data graph contains the
data plots from all 8 channels forming a micrography of the online graph.
