DDS offers the precision of digitally controlled logic--reducing the complexity of the generator while increasing the stability. Thus, allowing you to have a stable, accurate output signal for clean, low distortion sine waves and square waves with fast rise and fall time up to 20 MHz and linear ramp waves up to 200 kHz. The U2761A can generate pulses from 500 Hz to 5 MHz. With variable period, pulse width, and amplitude parameters, the U2761A is ideally suited to a wide variety of applications requiring flexible pulse width signals. Arbitrary waveform editor With every purchase of the U2761A, it is bundled with an easy-to-use application software, the Agilent Measurement Manager. This application allows customization of waveforms generation. 2 Internal modulation Internal AM, FM, PM, ASK, FSK, and PSK modulation makes it easy to modulate waveforms without the need for a separate modulation source. Linear and logarithmic sweeps are also built in, with sweep rates selectable from 1 ms to 500 s. Quick and easy to begin with ADE compatibility The USB 2.0 interface provides easy connectivity and setup that allows automatic detection of the U2761A. With quick and easy USB connectivity, the U2761A is ideal for academic and testing environment. The USBTMC 488.2 standard makes the U2761A compatible with any system that comes with USB ports. The U2761A is compatible with a wide range of ADEs. This minimizes development time because developers can program directly using the SCPI commands. Flexible standalone or modular capability The U2761A is uniquely designed with flexibility to function standalone or as a modular unit. The standalone PC-based unit allows you to have low start-up cost. Listed below are the popular development environments and tools that the U2761A is compatible with: * Agilent VEE and Agilent T&M Toolkit * Microsoft(R) Visual Studio .NET, C/C++ and Visual Basic 6 * LabView(R) * MATLAB(R) Product Outlook and Dimensions Easy-to-use AMM offers command logger function Better yet, Agilent Measurement Manager application software provides a quick and easy means to configure and control the device. This enhances productivity because it allows users to start performing measurement promptly without needing to write any programming codes. The Agilent Measurement Manager also comes with a command logger function that lets you capture commands that can be easily converted to VEE programs for VEE users.
