Audio measurements and Dolby, dbx noise reduction
Audio engineers in the 1970s became aware that many of the traditional distortion mitigating methods were unsatisfactory. In this context, dbx and Dolby noise reduction systems emerged. Dbx Type I and Type II vastly improved audio fidelity in analog tape reproduction. Dbx-TV is another system component that provides stereo sound for TV systems in the […]
Julia-language SDK handles digitizers, generators, digital I/O products
A Software Development Kit (SDK) for programming over 200 different digitizers, generators and digital I/O products uses the Julia programming language. A key feature of Julia is that it has been specifically designed for high-performance applications that require fast processing of data, like machine learning and scientific computing. For example, libraries include optimized source C […]
Bit errors and ADC testing
Most engineers are introduced to the basic performance parameters of analog/digital converters in school. So specifications such as SNR, SINAD (Signal-to-noise and distortion ratio), ENOB (Effective Number of Bits), and THDA (total harmonic distortion analysis) are all familiar ADC terms found in ADC data sheets. Ditto for an INL error, described as the deviation, in […]
New development chassis for 6U OpenVPX boards with VITA 67 RF, SOSA interfaces
A new three-slot 6U OpenVPX development backplane and chassis platform features the 6U OpenVPX power and ground only backplane with one VPX slot and dual VITA 67.3c slots with cutouts in the P3 and P6 sections of the board. The versatile design allows both VITA 65 and VITA 67 boards to be plugged into the […]
Test software quickly debugs/characterizes multi-gigabit automotive Ethernet designs
The Advanced Automotive Ethernet software portfolio helps automotive industry engineers, designers and manufacturers develop high-quality, high-performance products that improve safety in driving conditions and enable emerging advanced driver assistance systems (ADAS). Next-generation ADAS systems need camera and radar systems that deliver high resolution. This requires increased data rates and high bandwidth networking. Automotive Ethernet enables […]
Test suite brings Broadband Forum standard to Wi-Fi router testing
A new test suite handles the TR-398 Issue 2 Wi-Fi router performance test standard from the Broadband Forum. Customer care calls and truck rolls associated with Wi-Fi are a big pain point for service providers. They are looking for testing solutions that help them quantify the performance of a Wi-Fi router prior to releasing it […]
Testing Wi-Fi 6E performance
The 6 GHz band brings 1,200 MHz of additional spectrum to Wi-Fi which complicates the task of testing and verifying features. Eve Danel, LitePoint Now that the 6 GHz region of the spectrum is available for unlicensed use, Wi-Fi 6E devices are on their way to store shelves. Manufacturers face the juggling act of comprehensively […]
New 10-slot 3U development chassis for OpenVPX, SOSA designs
A new 10-slot 3U OpenVPX enclosure system is geared for SOSA (Sensor Open Standard Architecture) requirements. The new chassis platform features removable sidewalls, allowing the open frame enclosure to be optional fully enclosed. The 10-slot backplane has clocking and VITA 46.11 system management connections per SOSA requirements. It has multiple VITA 67.3c and VITA 67.3d […]
Economical force tester handles basic static, multistage, cyclic testing chores
Accuracy, repeatability, and documentation of results are important factors when applications and raw materials undergo force testing. The ideal test machine used for carrying out the force testing should be simple to operate and test results should be easy to read and export for further analysis. The digital Chatillon CS2 Series of force testers meets […]
