WavePro 900 Series
Speed Up Debug and Analysis
  

 

SMART Triggers® 

The WavePro scope’s trigger bar is simple to operate. Run the scope in normal or auto trigger modes or capture one-time events into scope memory up to 64 Mpts with a single-shot trigger. Triggering with WavePro is direct, easy to read and to understand.

SMART- Trigger provides the flexibility needed to quickly trigger on the specific signal characteristic or pattern you are searching for. Trigger not only on what you expect but also on abnormal signals. Exclusion triggers can exclude normal signals and capture only the abnormal ones, speeding up the debug of your circuits and systems. Trigger on signals down to 600 ps. All WavePro oscilloscopes include SMART Triggers. Select multiple threshold levels, as well as the pulse width, for the flexibility you need to catch the waveform you want to view and analyze.

Runt triggering is great for capturing logic signals that exhibit inadequate levels or spurious signals, interfering with circuit operation. With the exclusion/inclusion feature, the scope will only trigger on runt signals that are outside/within a specified range of pulse width.

 

Use HISTORY Views to Find Intermittents

Pressing the HISTORY button converts the scope into a fast Analog Persistence fault-finder. The lifetime of your signal is written into the History memory and mapped on screen. You can measure each signal, see its trigger time, and identify rare events. Up to 8,000 events can be acquired for playback. This is great when you have intermittent problems and want to know if they occur at a rate related to other circuit or system timing events.

Press “play” to replay the signal history and automatically scan and search from sweep to sweep. 

Stop when you see something of interest. The display shows the Analog Persistence view of all acquired sweeps as well as the individual sweep under inspection. When used with a Smart Trigger such as runt or slew rate, you can easily determine the rate of occurrence. The time of the trigger event is displayed with a resolution of 1 ns.

HISTORY lets you see the intermittent, trigger on the problem and find how often it’s disrupting your design.
