Keysight introduces 2 GHz RTSA for satellite communications operators

2 mins read

Keysight Technologies has unveiled a real-time spectrum analysis (RTSA) solution enabling up to 2 GHz RTSA bandwidth for use with the Keysight N9042B UXA Signal Analyser.

The software based RTSA solution is able to monitor satellite signals and interference, allowing satellite network operators to provide a much higher quality of service (QoS) to users.

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 QoS, satellite operators need to perform rigorous and accurate signal interference monitoring in real-time to identify anomalies and mitigate service degradation.

Keysight’s RTSA solution looks to address this challenge by enabling 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 RTSA application software offers a number of significant benefits, including:

Reduced Analysis Time: Keysight’s advanced field-programmable gate array (FPGA) technology 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 Wide Bandwidth Analysis: With support for ODI streaming at up to 2 GHz to RAID storage, this solution enables rapid, wide bandwidth streaming and capture of hours of signal recordings for analysis.

Digital Twin Innovations: Based on Keysight’s design and emulation expertise, the RTSA solution can accelerate innovation using digital twins that speed design and testing of satellite payloads, lower prototyping costs, and speed time-to-market.

Runs on Proven Keysight Technology: The RTSA solution is designed to run on the N9042B UXA Signal Analyser, an industry-leading signal analyser/spectrum analyser that tests mmWave performance in 5G, satellite, and radar.

When 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 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.

Commenting Greg Patschke, General Manager of Keysight’s Aerospace/Defence and Government Solutions Unit, said, “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 modelling software and radio link emulation, satellite network operators can use digital twins to reduce risk and cost while accelerating system development.”
