MSO/UPO2000-SPI Embedded serial bus trigger and analysis-SPI
Overview
The MSO/UPO2000-SPI adds SPI bus triggering, decoding, and search to your MSO/UPO2000 Series oscilloscope β a high-speed, full-duplex bus for flash memory, ADCs, DACs, display controllers, and SD cards.
Debugging SPI issues β 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 β Trigger on data patterns on MOSI or MISO, or chip select edges for specific transactions.
- Simultaneous MOSI/MISO β Decodes both master-out and master-in data in parallel β full-duplex visibility.
- Configurable Clock Modes β All four SPI modes (CPOL/CPHA combinations) for correct data alignment.
- Multi-Device Support β Decode transactions to specific slaves via chip select triggering.
- Lifetime License Activation β 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 β 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 β 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 β a one-time purchase that stays active for the life of the instrument. No subscriptions, no annual renewals, and no expiration.
