Flexible, future-proof PXIe vector signal analyzer covers 1 MHz to 3 GHz or 6 GHz In this video learn about Agilent’s M9391A PXIe Vector Signal Analyzer which covers 1 MHz to 3 GHz or 6 GHz and provides 40 MHz (standard), 100, or 160 MHz analysis bandwidth. The instrument features easily upgradable hardware with license keys. M9391A leverages PXIe to reduce RF components test times by enabling power servos to converge faster with outstanding linearity, repeatability and absolute amplitude accuracy. It is ideal for high speed embedded hardware accelerated Power, Spectrum and IQ measurements and in addition supports X-series measurements applications for modular instruments that include resource manager software to quickly switch between hardware commands and standards-based measurements. Agilent www.agilent.com Testing analog radio equipment digitally The CMA180 Radio Test Set from Rohde & Schwarz is designed for manufacturing tests and servicing of analog radio equipment. The instrument combines all features of a high-end product with a price level of a midrange instrument. The R&S CMA180 Radio Test Set covers the frequency range from 100kHz to 3GHz. Thanks to its large touch screen display and its clearly structured menu, it can be operated easily and quickly. Test signals are generated by an integrated ARB generator and controlled by software. Thus, users can generate any desired output signal shape at a bandwidth of up to 20MHz - a feature that normally characterize much more expensive instruments. The ease of operation also becomes visible in the way, users can generate additional signals just by a couple of mouse clicks - according to Rohde & Schwarz an industry first among radio measuring stations. For instance, users this way can generate interfering signals to test common-channel suppression. In addition, service technicians and test engineers can utilize the integrated sequencer to generate automated test runs. The power input of the CMA180 accepts signals of up to 100W continuous power and 150W peak - a feature that has no comparable test station. Thanks to its digital signal processing, the CMA180 achieves very exact results - something that makes the instrument suited for Software Defined Radios (SDRs). As an option, highly exact power measurement heads are available for power tests. Rohde & Schwarz www.rohde-schwarz.de Ceramic capacitors feature reduced acoustic noise A range of MLCCs from Murata have an extra interposer substrate that reduces acoustic “squealing” noise The ZRB series of monolithic ceramic capacitors (MLCC) is packaged on an interposer substrate designed specifically to reduce acoustic “squealing” noise typically induced by mechanical vibration of the capacitor. Available in the same size as conventional MLCCs, the ZRB is available in EIA 0402 (1.0 x 0.05 mm) and EIA 0603 (1.6 x 0.8 mm) package formats with working voltages of 6.3, 10, 16 and 25 VDC. With this approach, the ZRB becomes a replacement part to update an end-application design without the need for modification of the PCB layout. This form of acoustic noise has become of concern for the electronics industry and affects many types of consumer electronics devices such as laptops, tablets and smartphones. The PCB can (mechanically) amplify the audio noise generated by the capacitor, so by using an interposer substrate the MLCC becomes mechanically isolated from the PCB. Reduction in audio noise can be achieved against a traditionally designed MLCC. Murata Europe www.murata.eu Microcontrollers target capacitive sensing for HMI applications Silicon Labs’ energy-efficient capacitive sensing microcontrollers (MCUs) are aimed at human-machine interfaces (HMI). The C8051F97x MCU family combines Silicon Labs’ ultralow power technology with the industry’s fastest, most accurate capacitive sensing to provide touch control solutions for the Internet of Things, home/building automation, consumer and industrial markets. Silicon Labs’ F97x MCUs offer lowest energy consumption in active, sleep and deep-sleep modes, claiming the longest battery life of any 8-bit capacitive sensing MCUs. With 200 A/MHz active current, the F97x MCUs combine low energy consumption and system performance. The MCUs 2 sec wake time minimises energy consumption while transitioning from sleep to active mode. The F97x MCUs offer the lowest sleep mode energy consumption in their class: 55 nA sleep current with brownout detector enabled and 280 nA sleep current with a 16.4 kHz internal oscillator. The F97x MCUs target battery-powered and capacitive touch sensing applications for handheld industrial devices, toys, gaming machines and remote controls, as well as touch-panel switch replacements for white goods such as washers, dryers, ovens and dishwashers. The F97x MCU family offers capacitive sensing technology with sub-micro-amp (<1 A) wake-on-touch average current, 16-bit resolution and 100:1 dynamic range to support buttons, sliders, wheels, and capacitive proximity sensing with up to 43 channels and multiple scanning modes. They incorporate Silicon Labs SAR charge-timing capacitance-to-digital converter (CDC) technology.
