NI推出USB-5680功率仪表

2008年01月10日 09:14:00 中国传动网

2008年1月7日消息,美国国家仪器(NI)宣布推出该公司的第一款USB控制的RMS RF功率仪表,此仪表可提供小体积的用于自动化测试、测量和监督应用的灵活性解决方案。6 GHz NI USB-5680功率仪表以高测量精确性和宽泛的动态包装特征展现在用户面前,并且不占用很大的空间。其动力供应仅来自于USB线缆,新功率仪表也是便携式应用的理想选择,因为其仅用100 mA电流,不用再提供额外的电源。 传统的功率仪表以功率传感器或导线定位接近测试中的单元,及通过缆线连接位于传统仪表包装中精确的A/D转换器。利用最新的PC和A/D转换器技术,USB-5680在一个体积小于9.6立方英尺的包装中将两者结合起来,比具有同等效果的benchtop体积要小。USB-5680可直接且简易地在任何PC或PXI控制器上与USB接口相连接。
由于频率比较宽,高动态范围和测量的精确性,工程师们可以利用USB-5680 RMS功率仪表进行广泛的应用。 特点: 频率范围广:50 MHz 到6 GHz 体积小:8.5 X 3.0 X 5.6 cm (3.35 X 1.18 X 2.2英寸) 高动态范围:63 dB 振幅精确性:±0.18 dB 为实现全部仪表的性能,USB-5680结合执行软面板和直观的软件库帮助工程师快速安装他们的系统。需要测试连续的高达6Hz RF信号波的工程师可利用配有VXIplug&play兼容执行软件面板的卓越配置以促进交互式控制。在自动化测试和测量系统中结合USB-5680,工程师们可以应用简单的应用程序编程接口(API),结合NI的LabVIEW, LabWindows™/CVI和微软NET环境进行编程。 [FONT=times] original text [/FONT]
[font=times] NI Introduces USB-Controlled RMS RF Power Meter [/font]
[font=times][Color=#708090]NEWS RELEASE – Jan. 7, 2008 – National Instruments today announced the company’s first USB-controlled true RMS RF power meter, which provides a highly flexible solution for automated test, measurement and monitoring applications in a small footprint. The 6 GHz NI USB-5680 power meter features high measurement accuracy and wide dynamic range packaged in a size similar to a typical power head. In automated test applications, the small size frees up valuable rack space without sacrificing performance. Powered solely from the USB cable, the new power meter is also ideal for portable applications because it consumes only 100 mA of current without an external power supply. Traditional power meters feature a power sensor or head located close to the unit under test and connect via cable to an accurate A/D converter located in conventional instrumentation housing. Using the latest PC and A/D converter technologies, the USB-5680 combines both the sensor and the A/D converter in one package occupying less than 9.6 cubic inches – much smaller than the benchtop equivalent. The USB-5680 simply connects directly to an available USB port on any PC or PXI controller. With a broad frequency range, high dynamic range and precise measurement accuracy, engineers can use the USB-5680 true RMS power meter for a broad range of applications. Features include: • Small size: 8.5 by 3.0 by 5.6 cm (3.35 by 1.18 by 2.2in) • Wide frequency range: 50 MHz to 6 GHz • High dynamic range: 63 dB • Amplitude accuracy: ±0.18 dB To realize full instrumentation capabilities, the USB-5680 comes with a full-featured, executable soft front panel and intuitive, easy-to-use software libraries to help engineers quickly set up their systems. Engineers who need to measure continuous wave RF signals up to 6 GHz can use the USB-5680 in a stand-alone configuration with a VXIplug&play-compatible executable soft front panel to facilitate interactive control. To incorporate the USB-5680 in an automated test and measurement system, engineers simply use the intuitive application programming interface (API) with their programming environments of choice including NI LabVIEW, LabWindows™/CVI and the Microsoft .NET environment.[/color][/font]
