Aero Software Package for InfiniiVision X-Series Oscilloscopes

The Aero Software Package for Keysight’s InfiniiVision oscilloscopes enables protocol triggering and decode for the MIL-STD 1553 and ARINC 429 serial buses. This package also enables other advanced analysis capabilities including eye-diagram mask testing and frequency response analysis (FRA) to help test and debug electronic systems found in the aerospace & defense industrie

Introduction

The primary reason engineers use oscilloscopes to debug and characterize serial buses, such as MIL-STD 1553 and ARINC 429 is because of an oscilloscope’s inherent ability to characterize the analog quality of these signals. Performing analog characterization using an oscilloscope is often referred to as “physical layer” measurements. Table 1 lists the specific measurement capabilities that are enabled on each series with the Aero Software Package for Keysight Technologies InfiniiVision X-Series oscilloscopes.

Although there are many oscilloscopes on the market today from multiple vendors that offer aero-focused options, Keysight’s InfiniiVision X-Series oscilloscopes offer some unique measurement capabilities for debugging and characterizing the physical layer of aerospace/defense serial buses including:

• MIL-STD 1553 trigger and decode
• MIL-STD 1553 eye-diagram mask testing
• ARINC 429 trigger and decode
• ARINC 429 eye-diagram mask testing
• Dual-bus time-interleaved protocol lister display
• Hardware-based decoding for responsiveness
• Decoding of all frames captured using segmented memory

To learn more about these advanced measurement capabilities, refer to the list of Keysight aero-focused application notes listed at the end of this document.

Mask Testing (Pass/fail waveform limits)

If you need to validate the quality and stability of your electronic components and systems, the InfiniiVision oscilloscope’s mask/waveform limit testing capability, which is enabled with the Aero Software Package, can save you time and provide pass/fail statistics almost instantly. Mask testing offers a fast and easy way to test your signals to specified standards, as well as the ability to uncover unexpected signal anomalies, such as glitches. Mask testing on other oscilloscopes is usually based on software-intensive processing technology, which tends to be slow.

The InfiniiVision scope’s mask testing is based on hardware technology, meaning that they can perform up to 270,000 real-time waveform pass/fail tests per second. This makes your testing throughput orders of magnitude faster than you can achieve on other oscilloscope mask test solutions.
