Debugging SPI issues — wrong clock polarity/phase, chip select timing, data corruption at high speed? This decodes MOSI and MISO simultaneously, overlaid on clock and CS signals. 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 SPI Triggering — Trigger on data patterns on MOSI or MISO, or chip select edges for specific transactions. Simultaneous MOSI/MISO — Decodes both master-out and master-in data in parallel — full-duplex visibility. Configurable Clock Modes — All four SPI modes (CPOL/CPHA combinations) for correct data alignment. Multi-Device Support — Decode transactions to specific slaves via chip select triggering. 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: Flash Memory Verification — SPI flash returns unexpected data. Decode to verify commands and addresses on MOSI and see what the flash returns on MISO. High-Speed Signal Integrity — SPI works at 1 MHz but fails at 20 MHz. Overlay decode on the waveform to spot degraded edges, timing violations, or reflections. Compatibility This option is compatible with all MSO/UPO2000 Series oscilloscopes (MSO/UPO2102, 2104, 2202, 2204 and -S variants). The same capability is offered on other UNI-T oscilloscope families: MSO/UPO3000CS. Frequently Asked Questions Should I buy this individually or get a bundle? If you only need SPI, 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.
