PR833190 - Signal Analyzer 110 GHz Text automatically translated in your browsing language Automatically translated

For the characterization of components for high-bitrate, very high-frequency transmission lines used in various projects (including: RadKom, INVENT, AI-NET, GreenICT) have been developed and manufactured at the IAF, and a measuring station is already in operation that can measure these circuits with real signals. High-bitrate signals with carrier frequencies of currently up to 300 GHz are transmitted over a short air measurement distance. The transmission bandwidth is currently around 40 GHz and is to be increased to 100 GHz in further development steps. The data source is an existing AWG (original price: 250 000,- €), which has the necessary technical specifications to generate any currently possible modulation formats and/or signals with a very high bit rate (> 50 Gbit/s). The receiver is currently a Keysight signal analyzer, which can analyze up to 10 GHz signals and is therefore technically unable to analyze newer modulation methods or higher transmission data rates of more than 50 Gbit/s. The measuring system currently consists of the following components: Control software 1000676763, data sources: A630000/2018/102000; A630000/2018/102100, recipient: 1000702332and has a total value of 467.000€. Technical requirements: In view of the new requirements (higher transmission rates) and the future security of the measuring station, it is imperative to procure a signal analyzer that can fully exploit the performance of the components to be measured and is also equipped for future communication applications. For these higher transmission data rates, a receiver (signal analyzer) is required that meets the following characteristics: • Frequency bandwidth of at least 100 GHz • A sampling rate of at least 256 GSa/s • Min. 2 channels for the analysis of I and Q signals All existing devices are from the same manufacturer (Keysight). These are controlled by a common manufacturer-specific software that generates these complex signals and analyzes them again in the receiver. Manufacturer comparison: Through an extensive market research, observation of the market, visit to the relevant trade fairs, etc., we know that currently three manufacturers can offer oscilloscopes with a bandwidth in the high GHz range. The manufacturers are: Keysight: 110 GHz Tektronix: 70 GHz Teledyne LeCroy: However, only Keysight is currently able to manufacture and offer a bandwidth of more than 100 GHz. This is achieved, inter alia, through the application of a new patent ‘US 10367463B2’: This patent describes a new type of very broadband, sequentially connected amplifiers based on distributed structures that can be controlled in their amplification. These are used as preamplifiers in this device to amplify very small signal levels over the entire frequency range and thus enable the analysis of the data in the first place. The other two companies can only offer frequency ranges of 70 and 65 GHz, respectively. These reasons currently do not allow to procure a device from another manufacturer. Keysight has a unique position in the frequency range required by us. Thus, the requirements of VgV §14 (4) 2b are met and it is not possible to award the contract in competition.
