安捷伦Agilent DSA-X 96204Q 凭借其160GS/s的实时采样率 、62GHz的双通道带宽，堪称“世界上最快的示波器”。同时它也能提供四通道，33GHz带宽 80GS/s实时采样率，同样性能惊人。
同它的绝世速度相匹配的，是它高达50万美元，折合人民币310万的天价。
视频中做了两次简单的演示实验，第一个演示操作使用了 56Gb/s PRBS-15高频信号合成器对其真实性能和各项功能进行了简单的测试，并配合结构示意图简单地介绍了它的内部的工作方式。第二次演示操作则使用了两台 3.125Gb/s PRBS-7信号发生器同时模拟输出20GHz和40GHz高频信号，在两台MITEQ 毫米波 DSB三角平衡混合器和一对Avantek 20-40GHz YIG振荡器的帮助下，形成软件调谐超高频无线电脉冲信号，用以检验示波器的真实性能，结果令人满意，示波器成功地捕获，并通过后期处理成功地展示了检验信号。
In this episode Shahriar demos the world's fastest oscilloscope!
The Agilent DSA-X 96204Q offers 160GS/s of conversion rate with a bandwidth of 62GHz on two dedicated 'RealEdge' channels.
It can also provide 80GS/s conversion rate and 33GHz of bandwidth on four simultaneous channels. The unit demoed in this video is equipped with all available options and is valued at over 0.5 million US dollars.
The block diagram of various sub-systems of the oscilloscope are presented and the principle operation of the instrument is explained.
A 56Gb/s PRBS-15 signal is applied to the scope from a Centellax 2G2P5A (now Agilent N4975A) and the resulting data pattern is examined in real-time.
Various scope functions are also presented as well as the capability to observer bit failures at baud-rate using this instrument.
As a second experiment, two 3.125Gb/s PRBS-7 data streams are simultaneously up-convered to 20GHz and 40GHz respectively by using a pair of MITEQ mm-wave DSB tripple balanced mixers and a pair of Avantek 20-40GHz YIG oscillators.
The resulting two signals are combined by using a power-combiner and fed to the oscilloscope.
The capability of the instrument to act as an ultra-broadband software-defined radio is demonstrated by recovering the the two PRBS sequences simultaneously through DSP post processing.
The block diagram of this setup can be downloaded from The Signal Path website.
