Product of the Month: July 2017

Tektronix, Beaverton, OR, introduced the TTR500 Series USB vector network analyzer, a USB-based RF test instrument. It includes VectorVu-PC analysis software and built-in bias tee for testing active devices. The 2-port, 2-path S-parameter VNA features 100 kHz to 6 GHz frequency range, 122 dB dynamic range, less than 0.008 dB trace noise, and -50 to +7 dBm output power. The built-in bias tee allows for 0 to ± 24V, and 0 to 200 mA on both ports for active devices. The analyzer operates with any Windows PC or laptop, and VectorVu-PC software controls and calibrates the instrument. For automated test systems in design or manufacturing, the software offers programmatic support for SCPI commands, including command compatibility with common legacy VNAs for integration into existing test systems. In addition, the software offers an offline mode for data analysis with an output file format compatible with common EDA simulation tools. Accessories include a rugged carrying case, rack mount kits, phase-stable cables, attenuators, adapters, and calibration kits.

Flexibility in Low-Cost Microphone Array Systems

As more and more production items are required to comply with a variety of environmental standards, noise control is increasingly key to successful market placement. Effective control of testing costs is equally as critical as deployment of the systems themselves. The ADLINK's fully modular solution provides flexible configuration based on actual demand, while substantially reducing implementation costs, for highly efficient and precise measurement with minimal investment.

Connecting the Unconnected: Evolving Manufacturing Connectivity, Part I - Challenges to Brownfield Development

Learn about common obstacles encountered on the road to connected manufacturing, and preview some solutions provided by ADLINK and Intel. Cisco estimates that 92% of the 64 million manufacturing machines in worldwide operation are unconnected to any network, despite remaining in full use on production lines everywhere. To prevent considerable costs being incurred, viable optimization of existing machines embodies connection to the Internet, effectively integrating them into Smart Factory systems while maximizing acquisition and analysis of operational data, all within acceptable cost constraints.

Architectures for Implementing a Hardware-in-the-Loop System

Safety, availability, or cost considerations can make it impractical to perform all the necessary tests with the complete embedded control system. Using hardware-in-the-loop (HIL) simulation, you can simulate the parts of the system that pose these challenges. By thoroughly testing the embedded control device in a virtual environment before proceeding to real-world tests of the complete system, you can maintain reliability and time-to-market requirements in a cost-effective manner even as the systems you are testing become more complex. Download this whitepaper to find out more about implement a HIL system into your test environment.

Fabrication of Freeform Optics

Freeform surfaces on optical components have become an important design tool for optical designers. Non-rotationally symmetric optical surfaces have made solving complex optical problems easier. The manufacturing and testing of these surfaces has been the technical hurdle in freeform optic’s wide-spread use. Computer Numerically Controlled (CNC) optics manufacturing technology has made the fabrication of optical components more deterministic and streamlined for traditional optics and aspheres. Optimax has developed a robust freeform optical fabrication CNC process that includes generation, high speed VIBE polishing, sub-aperture figure correction, surface smoothing and testing of freeform surfaces. Metrology of freeform surface is currently achieved with coordinate measurement machines (CMM) for lower resolution and interferometry with computer generated holograms (CGH) for high resolution irregularity measurements.
