Analizator stanów logicznych Zeroplus Bus Expert II SD3.0 i eMMC

Product Overview

The Zeroplus Bus Expert II is a powerful tool for measuring and debugging eMMC5.1 and/or SD3.0 devices. To make measurements and debugging as fast and precise as possible, the manufacturer has equipped this 32-channel instrument with a 2Gb memory on each channel. In addition, the newly designed Active Probe significantly reduces distortion of the signal coming from the device under test. To make sure the user doesn't miss a single bit of an important signal, the long write lossless function in Protocol Analyzer mode will document everything, uninterrupted, for as long as local storage allows.

The 2-in-1 Protocol Analyzer (PA) and Logic Analyzer (LA) modes make it easy to analyze recorded signals. The protocol analyzer mode allows you to view, search and analyze signals in categorized packets, while the logic analyzer mode verifies status and checks timing for the device under test. What's more, the powerful software
software allows the user to easily and instantly search, statistic and analyze signals. Zeroplus Bus Expert II is the best choice for measuring and debugging eMMC 5.1 and SD 3.0 devices.
