• Instrument Specific Events
B2900 has the ARM-TRIGger model for each channel and actions (transition
and acquire), and provides following events.
• WaitingForAcquireArm1, WaitingForAcquireArm2
• WaitingForAcquireTrigger1, WaitingForAcquireTrigger2
• WaitingForTransitionArm1, WaitingForTransitionArm2
• WaitingForTransitionTrigger1, WaitingForTransitionTrigger2
• Measuring1, Measuring2
• Settling1, Settling2
All events can be configured by the signal level (or edge), destination, and other
parameters defined in IVI 3.15.

• Limitations
LXI trigger event functions provided by B2900 are a subset of the IEEE-1588
required by LXI Class-B. The following limitations exist for B2900.
• Timestamp in the event are ignored. (immediate trigger only)
• Delay and other timing parameters cannot be set. (always 0)
• It is not allowed to add/delete any events.
• The :ARM:LXI:COUNt command is not effective. (ignored)
