:TRIGger:SEQuence:TERM1
Command
:TRIGger:SEQuence:TERM1 { EDGE1 | GLITch1 | PWIDth1 | RUNT1 | SHOLD1
| STATe1 | TIMeout1 | TRANsition1 | WINDow1 }
This command specifies the trigger mode for the TERM1 state in the
sequential trigger (the Find (A) state in the Trigger Setup dialog box on
the oscilloscope).
There are five limitations associated with sequential triggering:
1 The Edge followed by Edge and Video trigger modes cannot be used in
sequential triggering.
2
The AND qualifier cannot be used when the Reset condition is based
upon a logical pattern.
3 The Pattern/State trigger mode that uses range as the When Pattern
selection can only be used for either the Term1 state or the Term2
state, but not both.
4 You can only use one long timer (>30 ns). Therefore, trigger modes that
use timers greater than 30 ns can only be used for either the Term1
state or the Term2 state, but not both. Some examples of trigger modes
where you might use a long timer include Pulse Width, Glitch, Window,
Edge Transition, and Timeout.
5 The alternating edge trigger mode cannot be used in sequential
triggering.
Limitations (3) and (4) deal with extended resources. Extended resources
refer to trigger modes or conditions that are only available to either the
Term1 state or the Term2 state, but not both at the same time. The
oscilloscope will figure out which state has access to these extended
resources based upon the conditions you setup in each of these states. If
you want Term2 to have a timer longer than 30 ns, you must first change
the timer associated with Term1 to be less than 30 ns.
Query
:TRIGger:SEQuence:TERM1?
The query returns the currently defined trigger mode for the TERM1 state.
