Tektronix MDO3EMBD Embedded Serial Triggering And Analysis Module

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.
