Identify Signal Integrity Issues Quickly and Easily

Today’s digital signals are increasingly complex. Designers of serial links and parallel busses want to quickly identify signal anomalies in their designs. Engineers have traditionally relied on hardware triggering and deep memory to capture such illusive events. However, these classic methods fall short in some key areas.

The Keysight Technologies, Inc. InfiniiScan software allows you to use an oscilloscope to identify signal integrity issues that hardware triggering is unable to find in your electronic designs. This innovative software scans through thousands of acquired waveforms per second to help you isolate signal anomalies.

InfiniiScan overcomes these classic limitations by using software to overcome the limitations of hardware triggering. InfiniiScan inspects individual waveforms and lets you know where the anomalies are.

InfiniiScan moves an oscilloscope a few steps closer to the ideal of a “Find Problem” button. InfiniiScan can also isolate events as narrow as 35 ps – well beyond the limitations of hardware-based approaches. With InfiniiScan, there is no need to manually inspect waveforms as InfiniiScan will scan a waveform automatically to identify a single waveform anomaly out of 10,000 screens of data without requiring programming.

Keysight InfiniiScan consists of three components, InfiniiScan software finders, measurement limit test, and two-stage and three-stage triggering.

InfiniiScan Software Finders

InfiniiScan software finders consists of five unique features: measurement finder, zone qualify finder, generic serial pattern finder, non-monotonic edge finder and runt finder.

Measurement finder allows you to set boundary conditions to the specified measurement results (inside/outside limits). The oscilloscope will then tell you if it finds such an event. For example, you can set a measurement finder to have the oscilloscope identify a rise time you specify.

Measurement finder will work with only the measurement that the oscilloscope makes. This provides insight that hardware triggering cannot find.

Zone qualify trigger

The Zone qualify finder allows you to draw a “must pass” or “must not pass” zone on the oscilloscope screen to visually determine the event identify condition. If you can see the event of interest on the screen, you can create a trigger that will isolate it, saving significant time over some complicated hardware triggers.

InfiniiScan now supports up to eight zones on screen, it also allows you to trigger on multiple channels. Boolean logic ties the channels together, allowing for an essential unlimited number of zone and channel combinational triggers. To change channel mapping, simply right click on the zone of your choice and choose the channel to which the zone is assigned.

InfiniiScan also provides a “hide zone” menu option that removes the zones from the screen, while still triggering with InfiniiScan. Use this feature to capture screen images without showing zones in the image.

Differential and common mode triggering

With Infiniium software version 2.01 or later, you can choose hardware accelerated differential and common mode channels. Combining this HW accelerated math and InfiniiScan yield the world’s first function trigger.

The generic serial finder lets you set up to an 80-bit serial pattern for the oscilloscope to identify up to 8.5 Gbs. Hardware solutions are currently limited to 40 bits and a maximum speed of 3.125 Gbs. Serial patterns can be expressed in hexadecimal or binary.

User-definable CDR (clock data recovery) methods are available. Fixed-frequency CDR is standard. Other CDR methods (PLL, explicit, etc.) are available if ordered in conjunction with Keysight’s EZJIT jitter analysis or serial data analysis software packages. Combine InfiniiScan with Infiniium’s protocol viewer tools for the ultimate protocol analysis on an oscilloscope.

InfiniScan’s runt finder allows you to identify under-sized signal pulses to resolutions that are beyond the capability of hardware approaches by using hysterisis and threshold levels you specify.

The non-monotonic edge finder is a unique capability of InfiniiScan. It allows you to identify non-monotonic edges caused by signal reflections. This feature is strongly demanded by the test and measurement industry to help identify poor signal terminations. There is no method for finding such an event with hardware triggering.

Two-stage and three‑stage triggers can easily be set up via the trigger menu. You can use InfiniiScan for first, second or third stage triggering.

For the 9000 oscilloscopes, you can get two-stage triggering by using the delay from hardware trigger control. Hardware trigger must be followed by InfiniiScan triggering after specifying a delay between the events. You can use the delay capability to facilitate a higher percentage of pre-finder and post-finder information.

Three-stage triggering easily combines both the 90000 Series’ powerful hardware triggering capability with InfiniiScan to form a powerful three-stage triggering system. This combines the speed of hardware triggering with the flexibility of software triggering.
