16CH 1.6GS/s Sampling Rate eMMC/SD Bus Expert

Overview

The Bus Expert is a 2-in-1 logic analyzer and protocol analyzer for the eMMC5.1 and SD3.0 protocols. It comes with specially designed active probes that are just perfect for acquiring the high-speed eMMC signals. In protocol analyzer mode, only eMMC or SD packets are captured, allowing for the capture of many subsequent events. The data can thereafter be analyzed using the special Bus Expert analysis functions or the standard functions of all our software solutions.

Special Functions

Channel Skew Correction: Time-align individual signals

Event Log: Search for packets, addresses, arguments, data, statuses, errors among 250M records

Event Trigger: 3 level CMD sequence trigger, Error Trigger, Busy Trigger

Protocol Analyzer Mode: Sample eMMC/SD events for hours or even days, supporting NCR, HS400 mode etc

Procedure Auto Test: Check that the command sequence is correct

Customization and Navigation

Languages: English, Simplified Chinese, Traditional Chinese

State List and Waveform View: Present the data as a list of 1s and 0s or as traces

Waveform and UI customization: Modify the appearance of channels, menus, traces etc.

Zooming and panning: 3 cursor modes

Triggering

Pre/Post Triggering: Store both pre-trigger and post-trigger data; choose from 0-100% pre-trigger data 

Protocol Trigger: Trigger on eMMC/SD commands and events

Pulse-width Trigger: Trigger on pulse widths

Trigger Channels:10

Trigger Delay: Delay acquisition after trigger event based on duration (time) or number of samples (memory)

Trigger Events: Byte/State/Edge/Width

Trigger In: Trigger on an external signal

Trigger Out: Send a trigger signal that sets off another instrument

Trigger Pass Counter: 1 to 65,535

Export: Export acquired data as .csv or .txt 

Files Comparison: Compare 2 files to quickly see where and how they differ

Real-time Signal Activity: Live view of probe activity

Trace Information: Display timing information inside the waveform

Auxiliary Analysis Windows

Navigator: Quickly get an overview and navigate to distant parts of the waveform

Memory View: See what the memory looks like; what is read/written to which address

Packet List: Breakdown of all packets details into convenient list form

Statistics: Table view of number of periods, periods that satisfy conditions etc 

Protocol Decoding

Protocol Decoders: Trigger on, decode and analyze the eMMC5.1 and SD3.0 protocols (and older version)
