Keysight Technologies, Inc. announced PathWave Advanced Design System (ADS) 2023 for high-speed digital (HSD) design with new Memory Designer capabilities for modeling and simulation of next-generation interface standards such as Double Data Rate 5 (DDR5). As data center throughput climbs, performance expectations of servers and high-performance computing drive the need for new high-density, ultra-fast memory or […]
Test setup verifies mobile industry processor interface A-PHY layer compliance
A new automotive serializer/deserializer (SerDes) receiver (Rx) compliance test solution verifies mobile industry processor interface (MIPI) A-PHY devices based on the Compliance Test Specification (CTS) requirements. This solution was developed in collaboration with BitifEye Digital Test Solutions GMBH and Wilder Technologies, with the support of Valens Semiconductor Ltd.. Silicon vendors are planning to implement MIPI […]
Semiconductor device modeling software adds model generator environment
Keysight Technologies, Inc. announced a new model generator (MG) environment that increases productivity for semiconductor device modeling engineers with improved automation across the entire workflow. Semiconductor device modeling engineers require automated tools to create accurate simulation models and process design kits (PDK) for baseband and radio frequency (RF) integrated circuit (IC) designs that leverage both silicon (CMOS) […]
Analyzing jitter with an oscilloscope
Jitter–basically the deviation between true and measured periodicity–is harmful beyond a certain level. In measuring jitter, we are calculating RMS, peak-to-peak deviation or spectral density. Jitter at frequencies below 10 Hz is known as wander. High-frequency signals are more prone to jitter than low-frequency signals. The deviation in periodicity that constitutes jitter may be in […]
The difference between impedance analyzers and network analyzers
At first glance, impedance analyzers and network analyzers seem to do the same thing: Describe the impedance of whatever is connected to their inputs. This statement is true as far as it goes, but as you might expect, there are significant differences between the two types of instrument. Here’s a review of the basics. There […]
Improved estimation of automotive radar signal strength
The signal strength of automotive radar can be estimated from the target radar cross section and distance. Greg Lee, Keysight Technologies Sir Robert Watson-Watt is generally credited as radar’s inventor, having developed the first practical system in 1935 and later applying radar to aircraft and weather. We’ve since used radar to monitor everything from ballistic […]
Open RAN test suite runs from the cloud
Keysight Technologies, Inc. announced that the Keysight Open Radio Access Network Architect (KORA) test solutions are moving to cloud-based deployment for improved flexibility and rapid deployment. In addition, the company’s LoadCore software for testing 5G Core (5GC), is now available as a metered, pay-as-you-go (PAYG) solution in AWS Marketplace to allow customers to scale costs with usage. AWS…
IMS 2022 video: Keysight Technologies
At the 2022 International Microwave Symposium, a combination of a signal generator and analyzer shows how noise floor affects dynamic range. A second video shows a test bed for a 141 GHz radio on glass for 6G research.
