100 GHz real-time measurement station

柏林理工大学“混合信号电路设计”(MSC)系由Dr.-ing教授领导。Friedel Gerfers与其研究小组“有线通信系统”和“无线通信系统”一起开发用于有线和无线高速通信以及汽车应用的电路和系统。目前的项目包括完整的收发信机和收发信机组件--以数据转换器为核心能力。有线项目包括数据速率高达224 Gbit/S(112 Gbaud PAM4)的收发信机，以及符号速率高达150 Gbaud的VCSEL和光调制器等组件，以推动数据中心(400和800千兆以太网)当前和未来传输技术的发展。无线频率范围可达D波段(最高可达170千兆赫)，用于将要开发的数据速率超过100Gbit/S的通信系统，特别是下一代手机“6G”。为了具有这项研究所需的表征能力，本提案要求100 GHz实时测量设置(“100 GHz EchtzeitMessPlatz”)，并在平行的提案中请求W和D频段频谱测量设置(“W-und D-Band SpektralMessPlatz(75-170 GHz)”)。100 GHz实时测量设置包括现有的70 GHz实时示波器的带宽扩展，这也是由2019年的一项重大研究仪器提案资助的，但当时该项目既不需要也没有资金机会将带宽扩展到100 GHz。提出了将带宽扩展到100 GHz的需求以及现有70 GHz实时示波器的过去使用情况。在当前的研究中，需要100 GHz的实时测量装置，例如，用于测量眼图及其特征特性(睁眼、误码率、码间干扰、噪声和抖动分析)，以及通过检查高次谐波(例如，7阶)的单音来进行线性观察。在这里，需要记录宽带、连续的数据流以进行可靠的分析，这就是采样示波器的子采样架构不能使用的原因。

The department "Mixed Signal Circuit Design" (MSC) at the Technische Universität Berlin, headed by Prof. Dr.-Ing. Friedel Gerfers, develops circuits and systems for wired and wireless high-speed communication as well as automotive applications with its research groups "Wireline Communication Systems" and "Wireless Communication Systems". Current projects include complete transceivers as well as transceiver components - with data converters as the core competence.Wired projects include transceivers with data rates of up to 224 Gbit/s (112 GBaud PAM4) and components such as VCSELs and optical modulators with symbol rates of up to 150 GBaud to advance the development of current and future transmission technologies in data centers (400 and 800 Gigabit Ethernet). Wireless frequency ranges up to the D-band (with up to 170 GHz) are used for communication systems to be developed with data rates of more than 100 Gbit/s, in particular for the next mobile phone generation "6G". In order to have the characterization capabilities necessary for this research, the present proposal requests a 100 GHz real-time measurement setup (“100 GHz Echtzeitmessplatz”) and, in a parallel proposal, a W- and D-band spectral measurement setup (“W- und D-Band Spektralmessplatz (75-170 GHz)”).The 100 GHz real-time measurement setup consists of the bandwidth extension of an existing 70 GHz real-time oscilloscope, which was also funded through a major research instrumentation proposal in 2019, but at that time neither had the project need nor the funding opportunity for a bandwidth extension to 100 GHz. The need of the bandwidth extension to 100 GHz as well as the past use of the existing 70 GHz real-time oscilloscope are presented in this proposal.The 100 GHz real-time measuring setup is required in the current research mentioned, e.g., for the measurement of eye diagrams and their characteristic properties (eye opening, bit error rate, intersymbol interference, noise and jitter analysis) as well as for linearity observation by examining single tones up to higher harmonics (e.g., 7th order). Here, broadband, continuous data streams need to be recorded for reliable analyses, which is why the subsampling architecture of a sampling oscilloscope cannot be used.
