True RMS self-powered AC voltmeter fits 30.5mm panel cut-out Murata’s DMR20-1-ACV is a self-powered four-digit bright LED voltmeter that can measure the true RMS value of its input from 85 to 264 VAC to within 0.1 V resolution. Designed to be completely self-contained, the low cost two-wire voltmeter requires no additional components or connections apart from the AC voltage it is measuring. It is capable of accurately measuring quasi-sine AC source such as modified, modified 2-step and modified 3-step sine wave in addition to conventional sine, triangle and square wave inputs. The voltmeter fits an industry standard “oiltight” 30 and 30.5 mm round panel cut-out. The 7.6mm four-digit LED display is housed in a rugged round polycarbonate case that provides protection against dust, moisture, vibration and shock. It is supplied with an EPDM rubber gasket and plastic hex nut that aid protection to IP67 / NEMA6 specification for water ingress. The DMR20- 1-ACV consumes a maximum of 30mA when used at 250VAC/60Hz. Murata Europe www.murata.eu Vector Software adds software test support for Green Hills’ Multicore OSs The VectorCAST software test platform now supports Symmetric Multiprocessing, Asymmetrical Multiprocessing, and Time-Variant Unified Multiprocessing under Multicore RTOSs from Green Hills Software. The multiprocessing support applies to the entire family of green hills’ OS, from the standard Integrity to Integrity-178b and Integrity-178 tuMP. Vector Software www.vectorcast.com Temperature Variable Attenuators TVAs from the recognized leader in high reliability resistive components offer: • Case size 0.150” x 0.125” x 0.018” • Choice of three temperature coefficient of attenuation (TCA) values: -0.003, -0.007, -0.009 • Attenuation values from 1-10 dB • Planar design with solderable or wire bondable terminations • Lower signal distortion, phase change and intermodulation compared with active circuit temperature compensation When the mission is critical, choose State of the Art. State of the Art, Inc. ResisTive PRoduCTs Made in the USA. Digital attenuators offer 50 Ohm RF steps Vaunix Technology has added an attenuation profile feature to its LDA series attenuators. The attenuation profile is user programmable with the capability to simulate various real-world fading conditions. The LDA series of Lab Brick Digital Attenuators includes 50 Ohm RF step attenuators with calibrated operation up to 6GHz. These units connect to a USB port for control and power and require no additional DC supply voltage. They are easily programmable for fixed attenuation or swept attenuation ramps directly from the included GUI. Lab Brick Digital Attenuator API DLL and LabVIEW-compatible drivers are also available for custom programming applications.
