Instant Familiarity and Insights

The single-screen operation, intuitive triggering and familiar Windows interface provide answers quickly and easily—so you can focus on debugging your design.

Fitting Your Work Style

Small-footprint standalone and PC-hosted models are available for integration into your debug environment. And offline analysis capabilities allow you to continue making measurements while you work at getting answers. These instruments work the way you work.

Getting there just got easier

When you’re debugging a design, you need to focus on solving your problems—not on mastering your debug tools. That’s the thinking behind Agilent Technologies’ 1680 and 1690 Series logic analyzers. These instruments work intuitively, so you can answer critical design questions without first becoming an expert in measurement instruments.

You’ll understand your logic analyzer right out of the box—thanks to the familiar Windows

-based features, the easy-to-navigate interface and the straightforward triggering. High performance doesn’t mean difficult to operate. Just turn the instrument on and you’re ready to solve.

Windows Familiarity and Single-Screen Operation

A familiar Windows-based user interface takes the complexity out of making logic analyzer measurements. You’ll feel right at home from the moment you turn on the instrument. And if you haven’t used your logic analyzer in a while, you won’t have to spend hours getting reacquainted with its features.

State Analysis

State analysis uses a signal from your system under test to determine when to sample. Because state analysis samples are synchronous to the system under test, they provide a view of what your system is executing. You can capture microprocessor and bus cycles and then convert the data into processor mnemonics or bus transactions with inverse assemblers from Agilent or one of our third-party partners.

Timing Analysis

Timing analysis uses the logic analyzer’s internal clock to determine when to sample system activity. With up to 800 MHz sampling and 4 M deep memory, you’ll see the order of events with high resolution over a long period of time.

Transitional Timing

If your system has bursts of activity followed by times with little activity, you can use transitional timing to capture a longer period of system activity. In transitional timing, the analyzer samples data at regular intervals but stores the data only when there is a transition on one of the signals.

Three measurement modes

During board turn-on and system debug, Agilent’s straightforward triggering capabilities help you quickly narrow in on the root cause of a problem. You can capture every aspect of your design, from a simple stuck bit to the complex sequence of events leading up to a timing problem. The intuitive triggering helps you identify the cause of elusive problems in less time—so you can get to your solution quickly.

Simple Trigger

Set the trigger according to how you think about your target signals. Use standard events, such as rising edge, falling edge or pattern, to define a trigger event. These events are accessible via an easy pull-down menu.

You can set the trigger for an event on the basis of activity on one or more buses or signals. Simply select the patterns, edge or levels for the signals that apply.
