虚仪科技推出基于电脑的高精度实时音频分析仪RTA-168

Grace
Grace over 15 years ago

虚仪科技(VIRTINS TECHNOLOGY)最近推出了一款基于电脑的高精度实时音频分析仪RTA-168(RTA,Real Time Analyzer)。该仪器由专业测量话筒、带话筒前置放大器的XLR转USB转换器和电脑虚拟仪器软件Multi-Instrument构成,并提供了一张精心配置的音频测试CD。整个系统配置小巧、灵活、方便,所有部件都可以放入一个专门配备的黑色软质工具小包内,可放入手提电脑包中与手提电脑一起携带,是在现场或实验室进行音频或电声测试的必备工具。该仪器在20Hz-20kHz的范围内,具有极其平坦的频率响应,且噪音低、失真小。可用于房间、听堂或汽车内音响的频率均衡调节及啸叫侦测、喇叭或音响的频率响应和失真测试、环境或工业噪声的监测和分析等。结合电脑强大的计算能力和虚拟仪器软件Multi-Instrument的强大功能,RTA-168提供了其他类似仪器无以伦比的性价比。由于采用了先进的数字信号处理技术,与传统的基于模拟电路的同类仪器相比,频率测量的精度和分辨率都得到了极大的提高。与同类手持式数字仪器相比,RTA-168具有运算速度快、功能更强大,而且可以不断进行升级等优点。RTA-168的主要功能包括:示波器、频谱分析、声级计、信号发生器、1/1、1/3、1/6、1/12、1/24、1/48、1/96倍频程分析、等效连续声级(Leq)测量、A、B、C、ITU-R 468频率加权、线性和对数时间加权、各种参数测量(THD、THD+N、SINAD、SNR、SMPTE IMD、DIN IMD、CCIF IMD)等等。虚仪科技还为注册用户提供了软件的永久性免费更新。
