Abstract

The ability to manage the effects of noise in components and systems is critical to performance. Noise can be added by power supplies, modulation, thermal and additive characteristics of devices. Phase-Noise, AM-Noise, Baseband Noise and Noise Figure must be fully characterized.
This workshop examines AM, residual and absolute noise, with cross-correlation techniques for measurement from DC to mmWave. We also discuss Phase-Noise applications across various instruments and the effects of external mixers on mmWave noise measurements. Lastly, we will show how Phase-Noise relates to Noise Figure and view the accuracy and limitations of Noise Figure Y-Factor and Cold Source methods.

Abstract

5GNR technology presents unique challenges to device manufacturers to not only find the room where to place the chipset, but also to ensure they perform as intended - in all the possible usage cases. This requires more validation testing at the design level prior to releasing prototypes for mass production. Production line testing lowers the risk of missing a company’s time-to-market and budget goals. In this workshop, we will review testing of 5GNR mmWave devices, and help attendees visualize why performance validation testing is required in all steps of the design process from the chipset level to production line testing.

Abstract

Achieving electromagnetic compatibility (EMC) for 5G devices is dependent upon the existence of achievable and appropriate regulatory requirements along with meaningful test methods for demonstrating compliance. The primary body in North America focused on developing EMC test methods for wireless and 5G devices, for both licensed and unlicensed transmitters, is Accredited Standards Committee C63 of the American National Standards Institute (ANSI). This workshop will begin with an overview of C63 and the standards most relevant to manufacturers of 5G mmWave devices. The overview will be followed by presentations focused on wireless coexistence and transmitter performance characterization and validation.

Abstract

In this workshop, we seek to demystify 5G signal construction, demodulation, analysis, measurements and conformance tests with a series of lab demonstrations, leveraging the PathWave Vector Signal Analysis (89600 VSA) software with measured data. As early 6G R&D at millimeter-wave/sub-terahertz frequencies is now underway, we will need new more flexible tools to address upcoming needs where different parts of the frame may have different IQ constellations or be used independently for synchronization, channel estimation and equalization. Fortunately, this added flexibility allows us to nimbly analyze communication signals hitherto cumbersome, like 802.11ay and DVB-S2X

Abstract

Almost all fields of high frequency electronics are rapidly expanding into mmWave frequencies. 5G (and 6G), SATCOM, Radar and EW systems are moving up to 100GHz. At mmWave frequencies non-ideal effects are not intuitive and common design practices do not help. One of the biggest challenges in system modeling is including layout parasitics from modules and boards. The coupling from one area to another on a layout is very difficult to tackle without sophisticated modeling and simulation tools. Keysight’s PathWave System Design (SystemVue) software has a new solution to identify both where the problem is and what is causing it.

Abstract

This workshop will describe and demonstrate how to emulate 4G/5G communication systems, including signal generation, transport, impairments, and monitoring/measurements, for network deployments which must overcome challenges such as Doppler shift, time delays due to multiple satellite hops, signal jamming, carrier-to-noise impairments, and signal combining and distribution.

Auditorium 6
Abstract

This workshop will cover optimized methods for setting up, calibrating, and evaluating measurement performance in coaxial probes up to 145 GHz and in waveguide bands spanning WR15 (75 GHz) to WR1 (1100 GHz) over a broad (-40 to 125c) temperature range.
We will present a novel means by which waveguide probes can be used for reliable over-temperature testing and calibration on an autonomous, semi-automated wafer prober whilst maintaining ease of operation and maximising directivity.
Practical programming examples using WinCalXE software will be demonstrated automating data measurement and analysis for on wafer parametric measurements, and to evaluate system stability and performance.

Abstract

Modern Radar and Electronic Warfare (EW) Signals have become increasingly complex in nature and therefore more complex to analyze. In this workshop, we seek to simplify the method to interpret and analyze EW signals of interest through a series of lab demonstrations leveraging 89600 VSA software, a UXA signal Analyzer and a UXR ultra-wideband oscilloscope. Advancements in both measurement hardware and software have yielded new capabilities and insights into signals, enabling the measurement and validation of complex EW waveforms.

Abstract

Communication systems require low phase noise elements to achieve high quality performance. Sensitivity in processing Doppler-shifted targets and EVM in complex digitally modulated communications can be adversely affected.
This workshop explains phase noise theory and its impact on performance of RF/microwave systems. We will describe multiple phase-noise measurement techniques, the role of the phase detector and the use of cross correlation in optimizing sensitivity, and we’ll discuss the impact of reference sources on phase noise measurements.

Auditorium 6
Abstract

Scientists have been investigating uncertainty in microwave measurements and have proposed models and techniques to quantify the individual contribution. These contributions can be systematically determined and added as part of a measurement, for small-signal S-parameters as well as large-signal power measurements. This empowers designers to report performance with uncertainties, and give the confidence needed to ensure product performance over time. We will introduce the theory and implementation of measuring S-parameters with uncertainty, the theory and implementation of measuring power with uncertainty, and show the effects of common components on S-parameters and power measurement uncertainty.

Abstract

Sub-terahertz frequencies (100-300 GHz) with extreme modulation bandwidths are part of early 6G research. This presents many unknowns. One of those unknowns is exploring the level of system performance that is achievable and reasonable given new frequency bands, extreme modulation bandwidths, and new waveforms. This workshop paper will provide insight into this by discussing new sub- terahertz system-level design and test challenges presented by 6G. EVM measurement results at 140 GHz will be shown with varying waveforms and bandwidths up to an occupied bandwidth of 10 GHz.
