Webinar: New Developments in Microwave Materials Measurements
Fundamental to microwave device design is knowing the electromagnetic performance of materials used in the device. Whether it is a microwave substrate, an antenna radome, or an electromagnetic inference absorber, methods are needed to evaluate materials and determine their intrinsic dielectric and magnetic properties. Designers use these intrinsic parameters (permittivity and permeability) to develop or optimize microwave and RF components. Measuring the performance of microwave materials requires a system that includes i) a measurement fixture and ii) a microwave analyzer. The fixture and the analyzer are usually connected with microwave or radio frequency (RF) cables.

Effects of Random Factors on the Metrology of VNA Measurement
VNA Master Class: Effects of Random Factors on the Metrology of VNA Measurement Webinar
Contributing factors to the uncertainty of a VNA measurement can be either random or systematic. Systematic errors may be greatly reduced through a calibration process such as Short, Open, Load and Thru (SOLT) or Thru, Reflect and Line (TRL), or any of a number of other methods. Random factors cannot be reduced by any algorithmic means because they are naturally random and unpredictable. However, certain measurement techniques can reduce them, which will be the topic of this webinar.

The Metrology of VNA Measurements, Errors, and Uncertainties
VNA Master Class: The Metrology of VNA Measurements, Errors, and Uncertainties
A fully metrological measurement made by a VNA is comprised of a value, a unit, an uncertainty, and the confidence interval of the uncertainty. Measurement uncertainty, or the accuracy, is stated on the VNA datasheet. Still, a complete understanding of the error components which contribute to overall uncertainty is helpful to inform and enable the user of the equipment to make the best possible measurements.

Using VNAs for High-Speed Digital Applications
VNA 101 Bootcamp: Using VNAs for High-Speed Digital Applications Webinar
Creating and evaluating high-speed digital designs now requires extensive knowledge of RF principles. Improperly designed power plane systems can couple noise from one section of the design to another. High-speed differential SRDES lines must exhibit proper characteristic impedance, and the sources of reflection must be properly understood. This webinar will address some of these issues and show how a VNA might be used to analyze and improve a high-speed digital design. USB-C and HDMI cables contain multiple high-speed twisted pair conductors. The four pairs in an HDMI cable may be thoroughly analyzed for differential Insertion Loss, Return Loss, and pair-to-pair Near and Far End Crosstalk (NEXT and FEXT) using the new SN5090 16-port VNA from Copper Mountain Technologies.

Starter mmWave Measurements with Eravant
VNA 101 Bootcamp: Starter mmWave Measurements Webinar with Eravant
This webinar will demonstrate Eravant’s VNA frequency extenders and their ability to perform full two-port S-parameter measurements of millimeter-wave components. The example test system will include Eravant’s Proxi-FlangeTM waveguide adapters, as well as the Wave-GlideTM positioning system. The VNA frequency extenders add full waveguide-band frequency coverage to several industry-standard coaxial VNAs, including models available from Copper Mountain Technologies. Proxi-Flange contactless waveguide flanges enable fast and repeatable connections between VNA frequency extenders and the waveguide components being tested. The Wave-Glide positioning system further streamlines component testing by maintaining the alignment between VNA frequency extenders and the components being tested while providing an easy and reliable method of inserting and removing tested components. Eravant’s metrology-grade calibration kits and Quick-Connect waveguide assembly tools will also be demonstrated.
