The Tektronix DPO4EMBD is an embedded serial triggering and analysis module that extends DPO4000 and MSO/DPO4000 series oscilloscope capabilities for debugging complex embedded systems. It delivers automated triggering, decoding, and search functionality across nine embedded serial protocols, enabling packet-level analysis on critical bus elements including addresses, data content, and identifiers.
– Technical Specifications
The module supports simultaneous decoding of up to four serial and/or parallel buses. Signal acquisition utilizes any analog channel (Ch1–Ch4) and, on MSO models, any digital channel (D0–D15). USB triggering and decode functions operate on all compatible models; HS triggering and decode are available on 1 GHz models in specific series only. Ethernet support is limited to MDO4000C Series (10BASE-T and 100BASE-TX compatible).
– Key Features
• Packet-level triggering on addresses, data, start of packets, and unique identifiers across multiple serial buses
• Protocol support: I2C, SPI, CAN, CAN FD, LIN, FlexRay, RS-232/422/485/UART, MIL-STD-1553, ARINC 429, I2S/LJ/RJ/TDM, USB, and Ethernet
• Bus display consolidates individual signals (clock, data, chip enable) for simplified packet boundary identification
• Decoded value display formats: Hex, Binary, Decimal, Signed Decimal, and ASCII depending on protocol
• Event table with time-stamped packet capture exportable to .csv format
• Search and mark functionality for user-defined packet criteria with rapid front-panel navigation
• Single-ended probing recommended for I2C and SPI; single-ended and differential probing for 10BASE-T; differential probing required for 100BASE-TX
– Typical Applications
Embedded system validation and debug across automotive, industrial, and communication platforms requiring multi-protocol bus analysis and correlation.
– Compatibility & Integration
Designed for Tektronix DPO4000 and MSO/DPO4000 series oscilloscopes. CAN FD and certain USB specifications are not available on MSO/DPO2000 Series.
