Chapter 1: Agilent Technologies 16712A 128K Sample Logic Analyzer

Setting Up a Measurement

Defined threshold voltage. The logic analyzer requires a minimum
voltage swing of 500 mV at the probe tip to recognize changes in logic
levels.

Step 3: Define Trigger Conditions (see page 14)

“Assigning Bits to a Label” on page 64

“The Format Tab” on page 53

Define Trigger Conditions

The third step is to define the trigger. The trigger settings tell the
analyzer when you want to capture data. Controls for this are located
under the

Trigger

tab. Configuration files saved from previous

measurements automatically define trigger settings.

Set Up a Trigger Sequence

The trigger sequence is like a small program that controls when the
logic analyzer stores data. There are trigger functions for the common
tasks, or you can set up your own. The logic analyzer starts at the first
trigger level, and stays there until the conditions described in that level
become true. When that happens, the logic analyzer goes to the next
level and follows the instructions there.
