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 = 103 samples/sec.)

trigger position = center (percentage of pre-trigger memory = 50%) acquisition depth = 64K (roughly 64 x 103 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.
