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.

柏林工业大学的“混合信号电路设计”系（MSC），由教授博士领导，Ing. Friedel Gerfers通过其研究小组“有线通信系统”和“无线通信系统”开发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器以及收发器组件-以数据转换器为核心竞争力。有线项目包括数据速率高达224 Gbit/s的收发器（112 GBaud PAM 4）以及VCSEL和光调制器等组件，符号速率高达150 GBaud，以推动数据中心当前和未来传输技术的发展（400和800千兆以太网）。高达D波段（高达170 GHz）的无线频率范围用于开发数据速率超过100 Gbit/s的通信系统，特别是用于下一代移动的电话“6 G”。为了具有本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”），并且在一个并行的提议中，W波段和D波段光谱测量装置100 GHz实时测量设置由现有的70 GHz真实的的带宽扩展组成。时间示波器，这也是通过2019年的一项重大研究仪器提案资助的，但当时既没有项目需求，也没有资金机会将带宽扩展到100 GHz。本文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属性（眼开度、误码率、码间干扰、噪声和抖动分析）以及用于通过检查单音调直到高次谐波（例如，第七阶）。在这里，需要记录宽带、连续的数据流以进行可靠的分析，这就是为什么不能使用采样示波器的二次采样架构。
