Keysight Technologies has launched real-time spectrum analysis (RTSA) for satellite communication systems with a bandwidth up to 2GHz.

The software-based RTSA system is based around the Keysight N9042B UXA Signal Analyser and monitors satellite signals and interference, allowing satellite network operators to provide the highest quality of service (QoS) to users.

This can then be used to accelerate development projects using digital twins, such as the one being developed with TTP,  to speed up the design and testing of satellite payloads and lower prototyping costs.

As the satellite communications (SATCOM) industry moves to high-throughput satellites, satellite network operators are experiencing increased satellite signals and interference. Signal interference has been further complicated for satellite operators with the auction of traditional SATCOM frequency bands to terrestrial wireless operators. To ensure high quality of service (QoS), satellite operators need to perform rigorous and accurate signal interference monitoring in real-time to identify anomalies and mitigate service degradation.

The RTSA system uses the N9042B UXA Signal Analyser to conduct continuous, gapless capture and analysis of elusive and transient signals with industry-leading optical data interface (ODI) streaming up to 2 GHz.

The FPGA technology in the analyzer enables a multi-threaded and parallelised RTSA measurement up to 2 GHz bandwidth to minimise the time gap between processing / rendering and re-capturing signals. This reduces analysis time and improves the probability of intercept.

Support for ODI streaming at up to 2 GHz to RAID storage enables rapid, wide bandwidth streaming and capture of hours of signal recordings for analysis.

Combined with the V3050A Frequency Extender for unbanded frequency coverage to 110 GHz, the U9361 RCal Receiver Calibrator, the M9484B VXG Signal Generator, and the powerful PathWave X-Series and PathWave Vector Signal Analysis measurement applications, the N9042B UXA analyser provides real-time spectrum analysis bandwidth to 2 GHz and streaming bandwidth to 2 GHz for satellite communication systems.

“With the introduction of our 2 GHz real-time spectrum analysis solution, Keysight is enabling innovators to push the boundaries for system performance in the satellite communication industry. By working with a partner like Keysight that can contribute both system-level modeling software and radio link emulation, satellite network operators can use digital twins to reduce risk and cost while accelerating system development,” said Greg Patschke, General Manager of Keysight’s Aerospace / Defence and Government Solutions Unit.
