To meet these growing demands, Siglent is expanding its portfolio with a new high-performance vector signal generator.
On March 12, 2025, Siglent introduced the SSG6082A-V vector signal generator, which features an output frequency range of 9 kHz to 8 GHz and a ±500 MHz bandwidth IQ baseband source, further expanding Siglent's vector signal generator product line. In addition, a new version of our SigIQPro PC software is scheduled for release in April 2025, adding enhanced support for Wi-Fi, 5G NR, LTE, and other common communication protocols, enabling more convenient generation of complex signals.
With a maximum frequency of 8 GHz and a peak output level of 30 dBm for CW signals, the new generator serves as both a high-precision RF source and a carrier for modulated signals. Its wide frequency range and power output meet the demanding testing requirements of many modern communication systems.
Wider modulation bandwidth and superior signal quality:
As data exchange rates between devices increase, broadband communication technologies are becoming more prevalent. The SSG6082A-V offers a modulation bandwidth of up to 1 GHz and excellent in-band response, thanks to precise factory calibration, making it suitable for a wide range of communication test scenarios.
The SSG6000A-V series features ultra-low phase noise, reaching -132 dBc/Hz with a 10 kHz offset for a 1 GHz signal. Higher spectral purity reduces test errors, improving the accuracy and reliability of measurement results. In wireless communication, low phase noise signals help minimize bit error rates (BER), improving the stability and reliability of the communication.
Phase noise at different carrier frequencies
For modulated signals, the SSG6082A-V offers an excellent adjacent channel power ratio (ACPR), ensuring high-quality signal generation while maintaining the target output power. This minimizes interference from neighboring channels during multi-channel testing, enabling more accurate simulation of real-world communication environments.

More accurate transmitter simulation:
The SSG6082A-V supports automatic amplitude, frequency, and phase compensation based on the test system's S2P file. This compensation minimizes phase fluctuations and phase noise while flattening the signal amplitude across the entire frequency range, ensuring consistent signal levels at different frequencies. With improved system compatibility, the SSG6082A-V fits a wider range of applications, delivering accurate and efficient test system performance.
Signal predistortion capabilities Use the S2P file to obtain a flat frequency response.
Outlook: More Protocols with SigIQPro and Comprehensive Testing Capabilities
As mobile devices continue to evolve with enhanced functionality, the demand for higher data rates and wider coverage is driving the need for more complex signal generation to validate device performance. SigIQPro is an essential communication testing tool, designed to generate high-quality, complex protocol and modulated signals. The next SigIQPro update, scheduled for release next month, will expand its capabilities to include LTE FDD/TDD and 5G NR signal generation, as well as additional WLAN signals, joining Bluetooth, IoT, custom IQ, and OFDM signal generation.
