Focus on test, measurement, and analytical equipment

NuView software from Bristol Instruments converts the company’s 438 series multiwavelength meter into a high-resolution optical spectrum analyzer. That capability allows the model 438 to analyze optical transceivers and wavelength-division multiplexing (WDM) signals. The meter simultaneously measures the wavelength, power, and optical signal-to-noise ratio of as many as 1000 discrete optical signals. Featuring high accuracy, a measurement rate up to 10 Hz, and a broad operational range of 1000–1680 nm, the model 438 provides precise, efficient, and versatile WDM testing for lasers and systems. For a more detailed analysis, the NuView software generates and displays an optical spectrum with a resolution better than 10 GHz (0.08 nm at 1550 nm). That lets users determine the transceiver side-mode suppression ratio and discriminate between closely spaced WDM channels.

Tektronix has brought to market three testing solutions designed to meet the requirements of advanced technologies for large, fast data transfers and low-latency video displays. The USB4, Thunderbolt 4 (TBT4), and DisplayPort 2.0 (DP2.0) automated compliance and debugging solutions easily integrate into test environments and address common test-time, signal-integrity, and device-under-test control challenges. They also offer physical layer electrical testing and characterization, which is crucial for compliance with the next-generation standards over USB-C connectors. The USB4, TBT4, and DP2.0 solutions can be used with DPO 70000SX, MSO 70000SX, DPO 70000DX, and MSO 70000DX oscilloscopes that have 23 GHz bandwidth and above and a sample rate of 100 GS/s. The scope setup can also be used for USB 2.0, USB 3.2, DP 1.2, and DP 1.4 testing. Tektronix Inc, 14150 SW Karl Braun Dr, PO Box 500, Beaverton, OR 97077, www.tek.com

Keysight has introduced a compact, ruggedized, handheld microwave analyzer to speed installation of 5G, radar, and satellite communications systems. The FieldFox supports an extended frequency and bandwidth range and has measurement integrity comparable to laboratory-based tools. It enables users in the field to install a millimeter-wave infrastructure and to reliably measure the network’s key performance indicators. The multipurpose tool has a task-driven user interface and incorporates spectrum and signal-analysis and signal-generation capabilities. It accurately measures signal interference, antenna and cable performance, levels of electromagnetic field exposure, and path loss in communications systems. It also ensures that 5G services in the frequency range 2 can reach full connectivity potential. Keysight Technologies Inc, 1400 Fountaingrove Pkwy, Santa Rosa, CA 95403-1738, www.keysight.com

The MeasureReady M81-SSM system from Lake Shore provides synchronous DC, AC, and mixed DC and AC sourcing and measuring to 100 kHz for very low-frequency and low-signal-level applications. The convenient system eliminates the complexity of multiple function-specific instrumentation setups and operates in cryogenic, room-temperature, and high-temperature environments. Up to three source and measurement modules can be connected. According to the company, noise and sensitivity are on a par with the best scientific-grade source and measurement instruments. The M81‑SSM is suitable for characterizing various test structures, including single- and multilayer atomic structures, MEMS, organic semiconductors, and superconductors.

According to Park Systems, its Park FX40 atomic force microscope is the first AFM to autonomously execute all setup and scanning processes. With integrated artificial intelligence and robotics techniques, intelligent learning features, and safety mechanisms, the Park FX40 can perform functions such as probe identification and exchange, beam alignment, sample location, tip approach, and imaging optimization. Built-in intelligence allows the AFM to autonomously image several samples according to user requirements. Environmental sensing self-diagnostics and the head-crash-avoidance system ensure optimum performance. Various key AFM aspects have also been upgraded, including electromechanics for much-reduced mechanical noise, smaller beam spot size, improved optical vision, and multi-snap-in sample chuck.
