Clock edge
The Clock Edge determines whether the instrument finds the trigger point on the rising edge (left button) or the falling edge (right
button) of the clock signal.
Level
Click in the Level entry box and use the multipurpose knob and to set the threshold on which you want to trigger. Different levels
are available depending on the code selected:
■ The upper level controls the upper level trigger point
■ The lower level controls the lower level trigger point
■ The clock level sets the clock threshold on which you want to trigger
Communication trigger codes and standards
The communication trigger standards available for an instrument depend on the bandwidth and or the configuration of that
instrument. Comm triggers are not available on DPO70000SX instruments. The following tables list the Communication Trigger
Codes and Standards available with Mask Testing.
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 on some instruments before you can
access the Comm triggers.
