• Inside: The measurement is inside the values set by limits A and B; limit A must be the low value
and Limit B must be the high value
• Outside: The measurement is outside the values set by limits A and B; limit A must be the low
value and Limit B must be the high value
The measurement block must be a measure or digitize building block that occurs in the trigger model
before the branch-on-constant-limits block. The last measurement from a measure or digitize building
block is used.
If the limit A is more than the limit B, the values are automatically swapped so that the lesser value is
used as the lower limit.
Example
TRIGger:BLOCk:BRANch:LIMit:CONStant 5, OUTside, 0.15, 0.65, 8
Configure trigger block 5 to check for measurements in the last measure or digitize block. If the
measurements are outside of the 0.15 and 0.65 limits, branch to block 8.

:TRIGger:BLOCk:BRANch:LIMit:DYNamic
This command defines a trigger model block that goes to a specified block in the trigger model if a measurement
meets user-defined criteria.

Usage
:TRIGger:BLOCk:BRANch:LIMit:DYNamic <blockNumber>, <limitType>, <limitNumber>,
<branchToBlock>
:TRIGger:BLOCk:BRANch:LIMit:DYNamic <blockNumber>, <limitType>, <limitNumber>,
<branchToBlock>, <measureBlock>
<blockNumber>
The sequence of the block in the trigger model
<limitType>
The type of limit (ABOVe, BELow, INside, or OUTside)
<limitNumber>
The limit number (1 or 2)
<branchToBlock>
The block number of the trigger model block to execute when the limits
are met
<measureBlock>
The block number of the measure or digitize block that makes the
measurements to be compared; if this is 0 or undefined, the trigger model
uses the previous measure or digitize block
