Overlaid Graphs: used to show the bursts from all channels overlaid. This<br />

can be used to assess coincidence of the detected bursts <strong>and</strong> hence the optical<br />

alignment: if the bursts overlap perfectly, the overlap of the measurement<br />

volumes is perfect. See chapter 4 for more details on how to check for<br />

coincidence.<br />

The System monitor display evidently requires some resources of the PC,<br />

which is not critical in low to medium data rate cases (data rate up to some<br />

kHz).<br />

Note In applications with high data rates, it is recommended to switch the System<br />

monitor off to free as many system resources in the PC as possible.<br />

To get an idea about the load on the PC, you can activate the Windows Task<br />

Manager (CTRL+ALT+DELETE – select Task manager) <strong>and</strong> compare the<br />

CPU load with <strong>and</strong> without the System monitor.<br />

Checking coincidence in 2D <strong>and</strong> 3D systems<br />

Note Please observe the rules for channel settings explained in section 0<br />

The System Monitor is useful for checking whether bursts arrive<br />

simultaneously on the velocity channels.<br />

By using the same trigger channel, the scope traces will have the same time<br />

base.<br />

Choose the trigger channel in the properties of the Coincidence group:<br />

By overlaying the traces, a direct visual impression of coincidence is<br />

possible. Right-click in the Scope part <strong>and</strong> select Overlaid Graphs<br />
