Oscilloscope Reference Communication triggering
Communication triggering
Communication (Comm) triggers are one type of trigger. Comm triggers are designed to work with
communication masks and standards. When you select a mask to test, it is associated with a specific
communicati
on standard. The mask you select determines the Comm trigger needed for that standard.
NOTE. The Comm Trigger is designed to work with communications mask and standard testing. Mask
testing automatically uses Communication triggers. You must install the Serial Communications Mask
Testing Option (see page 209) on s ome instruments before you can acc ess the Comm triggers.
Eye diagrams that are set up with an external clock use a time base position value large enough to
guarantee the edge is always before the acquisition record starts. This forces all Comm triggers to
disable the B-Trigger.
Even though Comm triggers are designed to work with masks, you can set up Comm triggering without
using a mask. You can also set up your own mask to use with Comm triggers.
