Isolated USB analog output modules support up to eight continuous waveforms Data Translation’s enhanced performance versions of its DT9853 and DT9854 USB analog output modules come with four or eight outputs with 16-bit resolution and can now also provide continuous analog waveform streaming at up to 8 kHz. ±300 V galvanic Isolation ensures safe operation, high signal integrity and excellent noise performance even in harsh industrial environments. All modules provide voltage outputs (±10 V, 0-10 V). The M versions have additional 0-20 mA current outputs supporting an external excitation voltage supply of 8-36 V. Key features include eight digital inputs, eight digital outputs and a 32-bit counter/timer. The interrupt on change function can be used on up to seven digital inputs to monitor and control critical signals. The analog output modules offer plug-and-play USB 2.0 connectivity to PC. They run entirely on USB power so that no external Power Supply is needed. The rugged enclosure as well as screw terminals for signal connections support industrial testing, control loop and process control applications. A comprehensive software package is included with the modules. In addition to Windows-compatible 32/64 bit drivers for Windows SDK or .NET, the package also provides interfaces for LabVIEW and MATLAB. Data Translation www.datatranslation.eu TCXOs comes with stabilities to ±1 ppm in custom frequencies up to 250MHz Fox Electronics now offers its XpressO TCXO with tighter stabilities in custom frequencies up to 250MHz. Available with ±1.5 ppm from -40 to +85°C as well as down to ±1 ppm from 0°C to +70°C, the XpressO-TC HCMOS TCXO oscillators can be delivered in ten working days or less. These new TCXOs are an expansion to Fox’s FXTCHE73 series that meets the humidity, shock and vibration requirements of MIL-STD-202. They are suitable for applications requiring very tight stability over temperature and low jitter, including medical monitoring and measurement, telecommunications and networking as well as military communications. Surpassing the typical 50 to 60MHz frequency range of traditional TCXOs, the new XpressO-TC oscillators offer a significant performance advantage, since custom frequencies can be specified up to 250 MHz. Fox’s proprietary ASIC technology, with a 3rd order Delta Sigma Modulator (DSM), enables XpressO oscillators to significantly reduce noise to levels comparable with traditional bulk quartz and SAW oscillators. This ASIC family enables the selection of output type, input voltages and temperature performance within the oscillator. Fox Electronics www.foxonline.com All-metal front pushbutton range offers IK10 shock protection and IP67 sealing EAO has improved the Series 82 pushbutton range with a set of design upgrades to give it the edge over other metal pushbuttons. Series 82 has been re-engineered from the inside out for extra strength, versatility and style. Featuring an all-metal front, IK10 shock protection and IP67 sealing, it is now one of highest specified pushbuttons on the market. Even extreme temperature fluctuations from -30 to +70°C and humidity up 85% will not affect operation. Control panel designer can now get the look and feel they desire through the wide choice of sizes, lens profiles, illumination styles and finishes including 16, 19 and 22.5mm diameter mounting-hole sizes, with dot or ring illumination, flat, raised or convex lens shapes and various finishes including stainless steel SUS 304 or chromed brass, gold coloured or aluminium anodised. Series 82 is suitable for ticket and vending machines, information terminals, access controls and door entry systems. All component materials adhere to RoHS and UL. EAO www.eao.com Switches cover DC to 6 GHZ for applications up to 50 through to 200 W KCB Solutions, an ITAR compliant and AS9100 certified microwave design and manufacturing center, has announced a suite of SPST through SP6T switches designed to meet high powerhandling requirements from 50 to 200 W. These switches are available in QFN-style packages and thermally conductive flange-mount packages. As an added feature, they are shipped to order in your choice of a variety of factory-configured ports. Designed and manufactured with PIN diode technology, they are 100 percent RF tested (small signal), have robust carrier construction, and are manufactured with thick deposition thin film traces. For power levels up to 50 W, KCB offers these high power switches in surface mount packages. They offer low-loss performance from DC to 6 GHz and robust construction. To address the need for switches that can handle powers in excess of 50 W, KCB has developed a flanged-based package. By utilizing an AlN carrier with a CuW sub-mount, the construction of these products offers superior heat spreading which allows for CW incident power levels up to 200 W. This, coupled with larger minimum breakdown voltages, provides the designer with a switch that is ideally suited for higher powered radios, Radar and counter IED systems. These models are available in configurations up to SP3T. KCB offers several off-the-shelf configurations as well as dozens of possible configurations that can be quickly realized using off-theshelf components. In addition, the designer can choose from a menu of diodes that provide optimal linearity for the application.
