Siglent SigVSA
Siglent SigVSA is a professional software for vector signal analysis, developed for flexible use on PCs running Windows and Linux. It supports both offline evaluation of IQ data and remote analysis of measurement tasks in everyday laboratory work. The software is designed for a wide range of signal types and offers a user interface tailored for efficient work in measurement technology.
With SigVSA, signals from various sources can be analyzed, documented, and compared. The software supports numerous IQ data formats and is therefore suitable for various development and test environments. It is particularly useful for the subsequent analysis of stored measurement data when signals need to be re-evaluated outside the actual measurement setup.
Siglent SigVSA is suitable for analyzing radio and communication signals in development and test environments. It covers a wide range of modern signal types, including BPSK, OFDM, LTE, 5G NR, and Wi-Fi standards from IEEE 802.11b to IEEE 802.11be. This makes the software a suitable solution for tasks in development, verification, and troubleshooting in wireless and broadband applications. In addition, it supports remote control and can control multiple measurement instruments in parallel, which makes laboratory workflows more efficient.
Typical applications include the evaluation of recorded IQ data, the investigation of modulation errors, and the debugging of signal waveforms in the lab. The software also offers clear advantages for the reproducible documentation of measurement results.
Another area of application is working with multiple measurement instruments in parallel when several signals or test setups need to be monitored simultaneously. In this way, SigVSA can help streamline test processes and enable the centralized evaluation of measurement data on a PC.
