Error Messages
When you insert a trigger function, the logic analyzer sets up a field for you
to enter values. The field length is based on the number of bits assigned to
the first active label, or the label you specify. If there are no bits assigned
to the label, the logic analyzer cannot complete the value field.

Trigger inhibited during timing prestore
The "trigger inhibited" informational message appears when you have a
logic analyzer making a conventional timing measurement, and it is
set to a slow sample rate. The logic analyzer will fill the designated
amount of pre-trigger memory before checking for the trigger
condition.
To calculate how long this should take, multiply the sample rate by the
percentage of pre-trigger memory and the acquisition depth. For
example, if
sample period = 1.0 ms (sample rate = 10
3
samples/sec.)
trigger position = center (percentage of pre-trigger memory = 50%)
acquisition depth = 64K (roughly 64 x 10
3
samples)
then the approximate time is 32 seconds.
Trigger Specification is too complex
The "Trigger Specification is too complex" message means that the
trigger sequence contains more unique event list expressions than can
be allocated to the available combiner resources in the analyzer
hardware.
