33 Trigger Commands
Advanced Delay By Event Trigger Commands
You can set the delay mode to delay by events or time. Use Delay By
Event mode to view pulses in your waveform that occur a number of
events after a specified waveform edge. Infiniium Oscilloscopes identify a
trigger by arming on the edge you specify, counting a number of events,
then triggering on the specified edge.

Arm On Use Arm On to set the source, level, and slope for arming the trigger
circuitry. When setting the arm level for your waveform, it is usually best
to choose a voltage value that is equal to the voltage value at the mid
point of your waveform. For example, if you have a waveform with a
minimum value of 0 (zero) volts and a maximum value of 5 volts, then 2.5
volts is the best place to set your arm level. The reason this is the best
choice is that there may be some ringing or noise at both the 0volt and
5volt levels that can cause false triggers.
When you adjust the arm level control, a horizontal dashed line with a T
on the right- hand side appears showing you where the arm level is with
respect to your waveform. After a period of time the dashed line will
disappear. To redisplay the line, adjust the arm level control again, or
activate the Trigger dialog.
Delay By Event Use Delay By Event to set the source, level, and edge to define an event.
When setting the event level for your waveform, it is usually best to
choose a voltage value that is equal to the voltage value at the mid point
of your waveform. For example, if you have a waveform with a minimum
value of 0 (zero) volts and a maximum value of 5 volts, then 2.5 volts is
the best place to set your event level. The reason this is the best choice is
that there may be some ringing or noise at both the 0volt and 5volt levels
that can cause false triggers.
Event Use Event to set the number of events (edges) that must occur after the
oscilloscope is armed until it starts to look for the trigger edge.
Trigger On Use Trigger On to set the trigger source and trigger slope required to
trigger the oscilloscope. Each source can have only one level, so if you are
arming and triggering on the same source, only one level is used.
