Test & Measurement

Test & Measurement Oscilloscopes with Increased Bandwidth Pico Technology has increased the bandwidth of its PicoScope 9300 family of Sampling Oscilloscopes with two new 25 GHz models. The USB-controlled Sampling Oscilloscope, available only from Pico, stands as one of very few low-cost, highintegrity options for viewing and measuring RF and microwave signals, paths and networks. Sampling Oscilloscopes are the cost-effective solution to today’s proliferation of gigabitper-second datastreams and their copper, wireless and optical fiber interconnect. The new 2 and 4 channel 25 GHz models, just added to the existing 20 GHz PicoScope 9300 Series, now support fifth harmonic capture for data up to including 10 Gb/s, and third harmonic capture up to 16 Gb/s. These rates, and others in between, are increasingly found in Ethernet, Thunderbolt, USB 3.1, PCIe 4, Rapid I/O, e-SATA, OC-192 / STM-64 and OC-256. All have transmission lines, cables, components, transmitters and receivers that need pre-compliance testing and characterization. “Low cost”? For most of us, owning a real-time scope with 25 GHz bandwidth is unrealistic, with prices starting from 0,000. Renting is usually the only option but even that can cost over ,000 per month! “Low cost” means that you can have a 25 GHz Sampling Oscilloscope, on your bench every day or where and when you need it, for the equivalent of 1 month’s rent of a 25 GHz real-time box. Having chosen your oscilloscope, you will want to probe your multiple broadband signals in-system and with minimal invasion of the measurement, all without interrupting system function. For this you will need the cost-effective, low-invasive, high-performance PicoConnect 900 probes. This is a comprehensive family of microwave and gigabit products. Uniquely configured as interchangeable AC or DC coupled probe heads in three division ratios (5, 10 and 20), these are ideally suited to in-system probing of analog, pulse, impulse and high-speed serial data streams. What’s more, they will interface to any other instrument type with 50 ohms inputs and likely outperform similar but manufacturer-locked accessories that you may have. All PicoScope 9300 Sampling Oscilloscopes can now be upgraded, free of charge, to full touchscreen operation with the latest PicoSample 3 software. PicoSample 3.25 also includes new masks for USB 2.0 and USB 3.1 Gen1 and Gen2. ■ Pico Technology, Ltd. www.picotech.com USB controlled TV Whitespace Generator RFMW, Ltd. announces application and sales support for the Telemakus TEG1000-10 USB controlled, RF generator. This laboratory quality generator offers a programmable RF output from 700 – 1000 MHz with 1 kHz resolution. Suitable as a low cost source for TV White Space design work, the TEG1000-10 provides performance similar to much higher priced generators such as: • Phase Noise of -105 dBc/ Hz@100 kHz offset • Spurious performance of -80 dBc • +10 dBm output power • -20 dBc second harmonic When coupled with other Telemakus USB controlled devices, complex text functions are achievable. Weighing less than an ounce, Telemakus test devices represent the latest technology in low cost, transportable test equipment. Each unit’s graphical user interface (GUI) is resident in on-board Flash memory making them “plug and play” for Window’s based PCs. ■ Telemakus, LLC Stocking Distributor RFMW, Ltd. info@rfmw.com www.rfmw.com 56 hf-praxis 6/2017

RF & Wireless Software CST Studio Suite Version 2017 Now Shipping Computer Simulation Technology (CST) announced the release of the 2017 version of the electromagnetic simulation tool, CST Studio Suite. The latest edition includes a range of new tools for synthesis and analysis and improvements to existing features. Test & Measurement Coordinate Measuring Machine Enhances Reputation Flann has taken delivery of its new OGP CNC 300 CMM (Coordinate Measuring Machine), which incorporates TTL (Thru The Lens) laser measurement and has a standard accuracy of +/-1.8 µm in XY & +/-2.4 µm in Z, although when used as CST Studio Suite is an electromagnetic (EM) simulation software package with solvers for a wide of applications across the electromagnetic spectrum, as well as multiphysics and particle applications. All of the CST tools are available within a single a comparator Flann expects to be able to realise +/-0.15 µm or better. It will enable engineers to automatically measure a part or assembly from an inspection program which can be written in conjunction with the engineering drawing, picking faces of the 3D model of the part and applying the geometric constraints and tolerances from the drawing. The new CMM will also help support Flann’s growing microwave and millimeter-wave waveguide component calibration and verification service to 500 GHz. A service that is fully traceable according to ISO9001 and ISO10012 whilst being underpinned by Flann’s many years of knowledge and expertise. ■ Pro Nova Elektronik GmbH www.pn-com.de graphical user interface and can be linked together for straightforward hybridization of simulations. CST Studio Suite is used in leading companies across the high-tech and manufacturing industries to develop new ideas, optimize products, and ensure standards compliance. The 2017 release of CST Studio Suite builds on the success of previous releases with new features for broader and more in-depth analysis of EM systems. The new tool Filter Designer 3D (FD3D) can automatically synthesize cross-coupled and diplexer filter designs to meet the specifications, including transmission zeroes, Q-factor, and equiripple. The complex and sensitive nature of these filters makes them challenging to design and tune with traditional methods. Coupling matrix extraction with FD3D offers an efficient way to finetune 3D filter structures. The new Interference Task offers a straightforward approach for investigating potential EMI issues using coupling data from simulations. The Interference Task shows at a glance which combinations of RF systems can potentially lead to co-site interference problems, allowing mitigation approaches to be tested on a virtual prototype. The ray-tracing Asymptotic Solver in CST Studio Suite can now directly calculate the coupling between antennas. The Asymptotic Solver can simulate extremely large platforms such as aircraft, ships, and buildings very efficiently, making it well suited to many kinds of antenna placement scenarios. This can be combined with the Interference Task for detailed co-site analysis of vehicles, vessels, and aircraft. Version 2017 also sees the expansion of CST Mphysics Studio tools with the Conjugate Heat Transfer (CHT) Solver. This uses computational fluid dynamics (CFD) to simulate the flow of air through devices, taking fans and vents into account. With the CHT Solver, users can include the cooling systems in their multiphysics simulation, allowing these systems to be designed and optimized before constructing prototypes. Shipping of CST Studio Suite 2017 has now started, and electronic delivery is available from the CST support area www.cst.com/ support. ■ CST Computer Simulation Technology AG www.cst.com hf-praxis 6/2017 57
