本文中Shahriar将会探访Teledyne LeCroy 制造工厂,亲身体验工厂车间的生产环境,亲手操作这款天价示波器。整个参观过程中可以看到这款示波器在手工生产线上的每个制造环节,示波器内部结构一览无余。
这款Teledyne LeCroy LabMaster 10-100zi 可以提供单通道100GHz带宽,或者是 双通道 33GHz和65GHz组合两种工作模式。能够达到如此高的性能指标,这款示波器采用了LeCroy自家独创的”频率交错“技术。这项技术使用了4个80GHz采样率ADC模块和3重频率交错硬件系统。
视频离拆解部分,近距离展示了这款示波器使用的ADC硬件模块,双重65GHz、3重100GHz频率交错系统。
操作实验部分则使用了两台非黏着性脉冲激光系统产生极高频率”光速“脉冲信号,成功地验证了这台示波器
高达100GHz带宽的性能,足以捕捉、处理 4 ps 时长的微弱脉冲信号。
Experiments and Teardown of the Teledyne LeCroy LabMaster 10-100zi 100GHz, 240GS/s Oscilloscope Published on Feb 9, 2015
In this world exclusive episode, Shahriar visits Teledyne LeCroy to take a close look at the operation, teardown and experiments with the LabMaster 10-100zi, 100GHz simultaneous bandwidth, 240GS/s real-time oscilloscope.
This instrument provides either a single 100GHz channel, or two 33GHz and one 65GHz digitizing channels.
The instrument uses a frequency interleaving technique invented and implemented at LeCroy.
The block diagram and the theory of operation of the scope is presented.
This includes the architecture of the 4x80GS/s ADCs and the triple frequency interleaving system.
The teardown of the scope includes a close look at the ADC platform, the dual frequency interleaving (65GHz operation) and the triple frequency interleaving (100GHz operation).
The experiments with the scope demonstrate the instrument's capability to digitize signals up 100GHz using the beat frequency of two non-coherent lasers.
The scope is also used to capture a 4pS rise time pulse from a femtosecond laser pulse system and a high-speed photo detector.
A complete factory tour is also presented where Teledyne LeCroy assembles all their oscilloscope products right here in the USA.
