MSO/UPO3000CS-SPI Embedded serial bus trigger and analysis-SPI
Overview
The MSO/UPO3000CS-SPI adds SPI bus triggering, decoding, and search to your MSO/UPO3000CS Series oscilloscope — a high-speed, full-duplex bus for flash memory, ADCs, DACs, display controllers, and SD cards.
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 UPO1000CS and MSO3000E Series oscilloscopes. The same capability is offered on other UNI-T oscilloscope families: MSO/UPO2000.
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.
