The differential 1-Mbps MIL-STD 1553 serial bus is widely used today in a broad range of aerospace/defense systems including aircraft avionics equipment, space-based systems, as well as many ground-based military vehicles. Due to the harsh electrical environment of military equipment, testing the quality of received and transmitted signals is very important. The primary measurement tool that engineers and technicians use today to test the signal integrity of serial buses is an oscilloscope. But capturing and measuring the electrical characteristics of MIL-STD 1553 signals have been a difficult and tedious process using conventional analog or digital oscilloscopes. Setting up a scope to trigger and synchronize on specific transmitted or received words often requires an external synchronization signal or guessing at a specific trigger hold-off setting. And then to determine the message information of captured and displayed communication packets/words requires a commonly used visual "bit-counting" technique, which is slow and prone to errors.

Agilent's InfiniiVision 3000 X-Series oscilloscopes provide MIL-STD 1553 triggering and decoding, as well as eye-diagram mask test capability to help you debug your MIL-STD 1553 buses faster.
