A high dynamic range enables more accurate and reliable measurements, which are critical in research, development, and production. The SNA6000A boasts a dynamic range exceeding 135 dB, making it ideal for detailed analysis of weak signals, even in the presence of stronger ones. This makes the analyzer a perfect solution for tasks such as measuring filters with low insertion loss and high stopband attenuation. Furthermore, the high dynamic range helps reduce signal distortion, improving signal integrity and calibration accuracy, especially in scenarios where minimizing external factors such as cables or adapters is essential.
In practice, calibration alone cannot always completely eliminate all external influences. Therefore, it is essential to have the right tools to mitigate interference from cables or test adapters. The SNA6000A series provides features such as an adjustable reference plane, adapter removal, and scaling/descaling to effectively address these issues.
Time Domain Reflectometry (TDR) capabilities enhance the VNA with the ability to thoroughly diagnose and characterize signal paths, lines, and cables. These functions can be added to the SNA6000A with the SNA6000-TDA and SNA6000-TDR options. The TDR option also enables the creation of eye diagrams, which are essential for assessing signal integrity in high-speed digital communications. Combining TDR with VNA allows for jitter analysis, crucial for examining the temporal stability of signals—both key characteristics in high-speed digital development.
Furthermore, the analyzer can be upgraded to perform pulse measurements, which is particularly beneficial when characterizing high-frequency components under real-world operating conditions, such as radar and communications systems. This method enables detailed analysis of components with short pulses, accurate evaluation of fast switching operations, and performance optimization in time-sensitive applications.
Integrating a spectral analysis function into a vector network analyzer (VNA) opens up new possibilities, especially in the development and testing of high-frequency amplifiers, oscillators, and communication systems. This extension is also available as an option: SNA6000-SA. It enables the precise analysis of harmonics, intermodulation products, and other nonlinear effects, while optimizing signal quality and bandwidth utilization in communication applications. Combining VNA and spectral analysis in a single device not only offers space and cost savings but also allows for deeper and more comprehensive signal characterization. This expanded measurement functionality leads to more effective diagnostics and a better understanding of the behavior of high-frequency components and systems.
In addition to the functions and extensions described, two further options are currently available. First, the SNA6000-SMM scalar mixer analysis, which allows measurement of frequency converter components. Second, the materials analysis option. This allows the VNA to determine important parameters for electronic applications, especially the permittivity and permeability of materials. An integrated formula editor and mask test help developers analyze the test object and accelerate the evaluation process. The large 12-inch touchscreen can be flexibly configured and allows for clear viewing of multiple windows displaying different measurements.
To characterize large RF networks within a comprehensive multiport test system, the SNA6000A can be paired with the Siglent SSM5000A series of switching matrices. Available with 2 or 4 input ports to suit the VNA, the system sequentially captures S-parameters through up to 24 output ports. With numerous switch configurations available, you can quickly design a customized test system tailored to your devices, offering exceptional value compared to competing packaged solutions. The SSM5000A series connects to the analyzer via USB or LAN, with automatic matrix detection and port assignment. Users can easily utilize it as a complete multiport vector network, with the software already integrated into the VNA firmware.
In short, the Siglent SNA6000A series offers a powerful solution for the increasingly demanding challenges in the field of high-frequency technology. The series impresses with its excellent core specifications, flexibility of use, and useful expansion options. Overall, the SNA6000A series represents a versatile, powerful and easy-to-use solution for the measurement and analysis needs of modern electronics.
