New real-time spectrum analyser presents solutions for critical communications

Aaronia AG will showcase the latest signal analysis solutions based on the SPECTRAN V6 USB real-time spectrum analyser at IWCE.

The analysis of communication radio channels in the complete frequency range from 27MHz to 7.125GHz and the investigation of satellite communication in the X-band and Ku-band is crucial. With the increasing use of these frequency bands for broadband applications, particularly in wireless communication and satellite services, new challenges emerge in spectrum monitoring and signal direction finding. Only with a comprehensive overview based on reliable and detailed information can the optimal use of the available frequencies be ensured.

In particular, the frequency range from 6GHz to 7.125GHz, which is increasingly used to expand 5G and Wi-Fi 6E, can only be analysed by a few solutions to date. Precise spectrum analysis is required here in particular in order to identify sources of interference and ensure signal quality. This is because different technologies coexist in this band, interfering a key challenge. The analysers in the SPECTRAN V6 PLUS series with an RTBW (Real-Time Bandwidth) of 245MHz enable seamless streaming of IQ data, which is unique in this bandwidth. If required, an RTBW with an enormous bandwidth of 490MHz can also be realised, an option that is otherwise only available on extremely expensive devices. This indicates that intermittent or short-lived signals that are difficult to detect with conventional methods can be made visible without any problems.

Another area of application is in satellite communication. In the X-band, which is used for defence and commercial applications, and in the Ku-band, which is essential for satellite internet and broadcasting services, precise analyses are crucial to ensure high availability and signal quality. USB real-time spectrum analysers allow a detailed examination of the signals for interference, modulation quality and bandwidth efficiency. Particularly with high-frequency signals in the 18 GHz range, environmental influences, atmospheric attenuation and multipath effects pose additional challenges that require continuous monitoring and analysis. The SPECTRAN V6 ECO series is predestined for measurements in these areas. The variants V6-100XA-18 and V6-150XA-18 have a frequency range of up to 18GHz and an RTBW of > 50MHz. Also, the already impressive standard sweep speed of around 500GHz/s can be increased to over 3THz/s via a single USB 3.1 port using a software license.

One of the biggest challenges in spectrum monitoring and direction finding in high-frequency areas is detecting and classifying signal sources in dense and dynamic electromagnetic environments. Since many systems work simultaneously, modern algorithms for signal detection and separation are required. In addition, the localisation of interference sources in urban and industrial areas is complex due to reflections and shadowing by building structures. The combination of real-time spectrum analysis with geo-referenced measurements and AI-supported analysis tools can help to identify and eliminate sources of interference more efficiently.

In addition to the real-time spectrum analysers listed above, devices from the SPECTRAN V6 Explorer series with waveguide technology can be employed here. The devices have been specially developed for microwave applications above 50GHz. The frequency range depends on the model and extends from 50GHz to 140GHz. A real-time bandwidth of 490MHz or sweep speeds of up to 3,000GHz/s is possible. Features are particularly vital for signal analysis in satellite links or monitoring defence communication systems. Here, precise measurements are required to identify frequency overlaps, signal distortions and unauthorised use.
