Vector Signal Generator with RF Test Capabilities
26 March 2025 - SIGLENT introduced the SSG6082A-V Vector Signal Generator, featuring 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. Additionally, a new version of the SigIQPro PC software is planned to be released in April 2025, adding further support for WiFi, 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 and power range meet the demanding testing requirements of many modern communication systems.
As data exchange rates between devices continue to rise, broadband communication technologies are becoming increasingly prevalent. The SSG6082A-V offers a modulation bandwidth of up to 1 GHz and excellent in-band response, thanks to precise in-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 at a 10 kHz offset for a 1 GHz signal. Higher spectral purity reduces test errors, enhancing the accuracy and reliability of measurement results. In wireless communication, low phase noise signals help minimize bit error rates (BER), improving communication stability and reliability.
For modulated signals, the SSG6082A-V delivers an excellent adjacent channel power ratio (ACPR), ensuring high-quality signal generation while maintaining the target output power. This minimizes neighboring channel interference during multi-channel testing, enabling more accurate simulation of real-world communication environments.
The SSG6082A-V supports automatic amplitude, frequency, and phase compensation based on the S2P file of the test system. 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 enhanced system compatibility, the SSG6082A-V accommodates a broader range of applications, delivering precise and efficient test system performance.
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 tool for communication testing, designed to generate high-quality, complex modulated and protocol signals. The upcoming upgrade of SigIQPro, set for release next month, will expand its capabilities to include LTE FDD/TDD, and 5G NR signal generation, and additional WLAN signals which will join Bluetooth, IoT, custom IQ, and OFDM signal type generation.
