Operating at 1 Mbit/s over redundant twisted pair, 1553 is in virtually every military aircraft. Protocol-level visibility overlaid on the electrical waveform for debugging timing and signal integrity simultaneously. The option is enabled by a software license keyed to the oscilloscope's serial number and is permanent for the life of the instrument. Key Features 1553 Triggering — Trigger on command/status/data words, RT addresses, subaddresses, or errors. Command/Response Decoding — Decoded transactions on the waveform — command word, status word, data words with RT address and word count. Response Time Measurement — Measures RT response time for compliance verification (4-12 µs requirement). Error Detection — Identifies sync, Manchester encoding, parity, and timeout errors. Lifetime License Activation — activate once, owned for the life of the instrument. No subscriptions, no renewals, no maintenance fees. When You Need This Option The option fits the following workflows: RT Development — Verify your remote terminal responds within the 4-12 µs window with correct status word content. Legacy System Maintenance — Search deep captures for intermittent 1553 errors, then examine the waveform for electrical root causes. Compatibility This option is compatible with all MSO3000X Series oscilloscopes: MSO3034X (350 MHz) and MSO3054X (500 MHz). The same capability is offered on other UNI-T oscilloscope families: MSO3000HD, MSO5000HD. Frequently Asked Questions Should I buy this individually or get a bundle? If you only need MIL-STD-1553, the individual license covers exactly that protocol. The BND bundle includes every protocol in the series. How is this option activated? The option is enabled by a software license keyed to the oscilloscope's serial number. After purchase, the license is registered on the UNI-T website to generate the license file, which is then loaded onto the instrument from a USB drive through the option-install menu. Refer to the oscilloscope's user manual for the step-by-step procedure. Is the license permanent, or does it require renewal? The license is permanent — a one-time purchase that stays active for the life of the instrument. No subscriptions, no annual renewals, and no expiration.
