The Tektronix MDO3EMBD is an embedded serial triggering and analysis module that extends MDO3000 series oscilloscope functionality with advanced protocol support for I2C and SPI serial buses. Engineers gain packet-level triggering, automatic message decoding, and search capabilities to accelerate embedded system development and debugging workflows.
Technical Specifications
• Protocol Support: I2C, SPI
• Maximum Data Rate (SPI): 10 Mb/s
• Maximum Data Rate (I2C): 10 Mb/s
• Signal Inputs: Any analog channels (Ch1–Ch4); digital channels (D0–D15) with MDO3MSO option
• Probing: Single-ended recommended
– Key Features
• Advanced Triggering — Trigger on packet-level information, address fields, and data elements. SPI-specific triggers include SS Active, MOSI, MISO, and combined MOSI/MISO. I2C data trigger accepts 1 to 16 bytes of user-defined data.
• Automatic Decoding — Eliminates manual bit-level analysis. Bus display renders individual signals (clock, data, chip enable) as a unified protocol view, clearly showing packet boundaries, addresses, data, identifiers, and CRC fields.
• Event and Search Tables — Time-stamped event table summarizes decoded serial activity; automated search marks all occurrences of user-defined criteria with rapid front-panel navigation. Both tables support .csv export.
– Typical Applications
Ideal for engineers and system integrators debugging I2C and SPI communication in microcontroller-based systems, sensor interfaces, memory devices, and multi-master configurations requiring protocol-aware triggering and long-acquisition analysis.
– Compatibility & Integration
Designed for Tektronix MDO3000 series oscilloscopes. Purchased independently or bundled at initial scope acquisition. Licenses transfer between module and instrument, enabling flexible deployment across the lab bench.
