To trigger on the cycle count, you have to define a condition and one or two numbers. If
the condition is a range ("In range" or "Out of range"), a second number "Cycle count
max" is required.
Also, you can define a "Step" to trigger on each n-th cycle inside the given range. This
allows for specific triggering if slot multiplexing is used.
If the cycle count is not relevant for the trigger setup, set it to "Off".
Trigger type: "Identifier + data"
Remote command:
TRIGger<m>:FLXRay:CENable on page 1874
TRIGger<m>:FLXRay:CMIN on page 1874
TRIGger<m>:FLXRay:CMAX on page 1875
TRIGger<m>:FLXRay:CSTep on page 1875
Position, Index (min, max) - Data setup
Sets the position of the first byte of data bit pattern within the payload segment. You
can define an exact position, or a position range.
Trigger type: "Identifier + data"
"Position"
Operator for the data position. Select "Off", if the position of the
required pattern is not relevant for the trigger condition.
"Index"
Sets the number of data bytes to be skipped after start of the payload
segment if "Position" is "Equal" or "Greater or equal"
. The index 0 is
associated with the first data byte.
"Index min, Index max"
If the "Position" operator defines a range, the indexes of the first and
the last byte are defined between which the required bit pattern may
start.

Condition, Data (min, max) - Data setup
Specifies the data bit pattern to be found in the payload segment. The starting point of
the pattern is defined by "Position, Index (min, max) - Data setup" on page 627. The
pattern comparison is byte-aligned, and the instrument triggers at the end of a byte.
"Condition"
Sets the operator to set a specific data pattern ("Equal" or "Not
equal") or a data range. Select "Off", if the data pattern is not relevant
for the trigger condition.
