What's New in RF System Design and Simulation?

System Design (SystemVue)

System Design (SystemVue) 2025

SystemVue 2025 is the premier electronic system-level design, modeling and verification environment, capable of creating an RF digital twin of the wireless systems.  The 2025  release delivers seamless integration of system and circuit workflows, enhanced power amplifier modeling, simulation optimization, and advanced SATCOM and Non-Terrestrial Network (NTN) features, along with Artificial Intelligence and Machine Learning (AI/ML) model integration for 5G Advanced and pre-6G use cases.

Key new capabilities include HPC support for Spectrasys and Phased Array Analysis (Windows and Linux), Design Cloud Lite support, WLAN IEEE 802.11bn transmitter and EVM measurement, 5G NTN link budget analysis, pre-6G Integrated Sensing and Communication (ISAC), and the new RaySim 3D Ray Tracing channel model. Additionally, the DPD/Modulation Explorer has been updated with mixer support, template improvements, and bug fixes, alongside high-priority stability and performance fixes across the platform.

Leveraging Keysight’s measurement and testing expertise, these tools provide engineers with a holistic, high-fidelity digital twin environment that accelerates virtual prototyping, ensures precise validation, and reduces risk before physical implementation—empowering faster, more confident innovation in 5G and 6G as well as aerospace/defense, radar and satellite applications.

SystemVue High-Performance Computing 

The W4581 SystemVue HPC Design Cloud accelerates and manages multiple parameterized sweep simulations for RF, Phased Array, and Dataflow designs. It provides a comprehensive set of job creation, allocation and submission capabilities, and returns results as a single dataset. 

The HPC license leverages High-Performance Computing (HPC) technologies that enable users to run parallel simulations in the cloud, cluster, or server to make sure jobs are automatically allocated to the right resources for maximum application performance and efficiency. 

Communications system architects, verification engineers, and baseband designers use the HPC license to accelerate architecture studies and verification suites, while reducing costs and accelerating time-to-results.

Non-Terrestrial Networks Modeling (NTN)

• New examples have been added to demonstrate complete NTN link budget analysis with downlink/uplink 3GPP NB-IoT waveform as an example

Modulation Explorer in ADS

Modulation Explorer is an embedded application in Keysight's Advanced Design System (ADS). It enables users to configure various signal formats such as  5G NR, LTE, WLAN, and I/Q user definitions to test their circuit design in ADS. The signal is generated and fed into the circuit design, and measurements are performed on the circuit's output, like Spectrum, ACLR, EVM, etc.

• When the SignalType is 5G NR DL and NR DL Signal Type is Test Model, base station conformance tests are conducted according to 3GPP TS 38.141-1.
• When the SignalType is 5G NR UL and NR UL Signal Type is Common Config, UE conformance tests are conducted according to 3GPP TS 38.521-1.
