• Execution Speed for Host and Device Transmitter Tests Minimizes Compliance Test Time as well as Complexity and Possibility of Human Error
• UHS2 provides Validation and Design Engineers the Ability to Run Tests on Stored Waveforms
• UHS2 covers both Informative and Normative Measurements for Host Devices
• Compliance Testing becomes Very Important with the Next-generation SDXC Memory Card Specification which Supports Increased Bus Interface Speeds up to 1.56 GB per Second or Higher and Dramatically Improves Consumer Experiences by Increasing Storage Capacity to 2 TB
• Detailed Test Reports with Margin and Statistical Information Aid Analysis
• Provides Engineers with a Tektronix Floating License Installation Option
• If Device Under Test is Not Available, Design Engineers can be Provided with AWG-based Patterns which will Simulate the DUT

Comprehensive Test Coverage

UHS2 software can be installed and run on Tektronix DPO/DSA/MSO oscilloscopes with bandwidth greater than equal to 6 GHz. Design engineers can always install UHS2 on their existing Tektronix oscilloscopes. UHS2 Debug Software Tests are based on the SD (Secure Digital) Version 4.0 Specifications, a set of industry standards which promote Secure Digital technology and products.

Plots and Results

The DPOJET Plot feature can further help characterize UHS-II devices. The Result section helps design engineers to look at the test results quickly and clearly. The Report section includes details of each test including Limits, Measured Value, Pass/Fail Results, etc.

Detailed Reporting Feature

The UHS2 application generates thorough HTML reports that capture the performance, status, and test results of your device. It also captures screenshots of the measurements for future reference. Engineers have the option to store the report under a different name and at a different location. Report generation tools also provide features such as Auto Incrementing, Inserting User Comments, Listing Complete Configuration Details, etc.
