Using the Trigger Menu

Specifying a Basic Trigger

To define a term

Both default triggers trigger on term "a". If you only need to look for the

occurrence of a certain state, such as a write to protected memory,

then you only need to define term "a" to make the measurement you

want.

1 In the Trigger menu, select the field at the intersection of the

term and the label whose value you want to trigger on.

You set labels in the Analyzer Format menu. If the channels you want

to monitor are not attached to a label, they will not appear in the

trigger menu.

2 Enter the value or pattern you want to trigger on.

If the label's base is Symbol, a pop-up menu appears offering a choice

of symbols. For other bases, use the keypad. An "X" stands for "don't

care".

If there are two conditions that need to be present at the same time, for

example a protected address on the address bus and a write on the

read/write line, define both values on the same term. See the figure

below.

3 Press Done.

Term "a" Defined as a Data Write to Read-Only Memory
