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 — 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.
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.
- Software License Activation — License key applied through the instrument menu. No hardware changes, no downtime — enter the key and start decoding.
When You Need This
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.
Compatible Instruments
This option is compatible with all MSO/UPO2000 Series oscilloscopes (MSO/UPO2102, 2104, 2202, 2204 and -S variants).

Frequently Asked Questions
Should I buy this individually or get a bundle?
If you only need SPI, the individual license at $219 is the most economical. The BND bundle ($595) includes every protocol at the deepest discount.
How is this option activated?
You receive a license key after purchase. Enter the key in the instrument's menu under System → Options → Install. The capability is available immediately — no reboot, no hardware modification, no factory service required.
Is the license permanent or subscription-based?
All UNI-T software option licenses are permanent, one-time purchases. Once activated, the option remains available for the life of the instrument. No annual renewals or subscription fees.
