SIGLENT Launches 8 GHz Active Differential Probe for High-Speed and RF Applications
SIGLENT introduces the SAP8000D Active Differential Probe, designed to address the challenges of high-speed signal characterization and RF testing.
Featuring 8 GHz bandwidth and ultra-low 300 fF input capacitance, the SAP8000D minimizes probe loading effects while preserving signal integrity in demanding measurement environments. The probe supports both differential and single-ended measurements and provides high common-mode rejection for improved measurement accuracy.
The SAP8000D is well suited for high-speed serial bus validation, signal integrity analysis, and high-frequency circuit debugging across applications including PCIe, DDR, USB 3.0, and Gigabit Ethernet.
To accommodate a wide range of test setups, the probe supports multiple probing methods, including solder-in, handheld, and fixture-based configurations, and is compatible with various probe accessories. This flexible design enables engineers to perform reliable measurements in complex test environments with greater confidence.
By combining high bandwidth, low input capacitance, and versatile connectivity options, the SAP8000D provides an effective solution for next-generation high-speed and RF measurement challenges.
Siglent Releases SigVSA Vector Signal Analysis Software
Siglent officially launched the next-generation SigVSA Vector Signal Analysis Software, bringing professional vector signal analysis capabilities to engineers’ desktops. Compatible with both Windows and Linux operating systems, the software enables comprehensive measurements ranging from basic BPSK signals to complex wideband signals (e.g., UWB, LTE, 5G NR and 4096QAM), delivering an efficient, flexible and unified signal analysis platform for the R&D, testing and manufacturing of wireless communications.
SigVSA offers two application forms: Desktop and Embedded, supporting full-process collaboration from R&D to production. The Desktop version runs on PC, breaking the limitations of instrument hardware and providing a flexible operating environment for complex wideband signal analysis. The Embedded version is deeply integrated into Siglent oscilloscopes and spectrum analyzers (e.g., SDS7000A with the RFA option), enabling high-precision signal analysis without an external PC and simplifying test setups. Both versions share a consistent user interface and measurement engine, ensuring a seamless operational experience.
SigVSA boasts rich measurement functions, currently supports mainstream wireless communication standards including 5G NR/NR-A, 5G NR-NTN, LTE/LTE-A FDD/TDD, Wi-Fi 802.11 a/b/g/n/ac/ax/be, Bluetooth, HRP-UWB and FHSS signals. Signal analysis functions for NB-IoT, GSM, WCDMA, DVB-S2/S2X and FMCW will be launched successively. SigVSA supports synchronized multi-device acquisition and analysis, allowing remote control and waveform capture for up to 32 instruments simultaneously. Equipped with remote management capabilities, it enables one-click device configuration switching, automatic connection record saving, and configuration synchronization from the host to the analyzer. Its multi-window display and custom layout features further enhance the efficiency of parallel multi-task analysis.
SigVSA provides comprehensive local analysis capabilities, supporting direct import and analysis of raw waveform files from analyzers for flexible offline signal evaluation. Additionally, SigVSA enables remote signal analysis and debugging on a PC, allowing simultaneous control of multiple instruments to acquire and process signals, without relying on the instrument’s vector analysis options, expanding its applicability and device compatibility. With SigVSA, engineers can tackle various signal analysis challenges more freely and efficiently.
Siglent has launched attractive promotional policies and flexible licensing plans, greatly lowering the barrier to use. From June 22, 2026 to June 22, 2028, purchasing an SDS7000A oscilloscope with the RFA option will receive full-feature of Embedded SigVSA free of charge, enabling complete high-end signal analysis functionality. Furthermore, the SigVSA PC version is available for free download, with the base version including three core functions: Spectrum and IQ Analysis (SIGV-VSAA1), Digital Modulation Analysis (SIGV-VSAD1), and Custom OFDM Modulation Analysis (SIGV-VSAO1). TRY BEFORE YOU BUY! Confident in its performance, SigVSA offers 30 free trials for each function, enabling you to evaluate its powerful analysis capabilities risk-free.
