Measuring a Diplexer with a 2-Port VNA

In this video, Brian Walker will walk through the process of tuning a diplexer using a 2-Port VNA.

See What Can’t Be Seen with VNA Measurements

At IMS 2023, Microwaves & RF editor David Maliniak stopped by the CMT booth at chat with Brian Walker about the demo showcasing an embedded measurement module to sense something that cannot be seen with VNA measurements. Watch the video to learn more!

Connecting and Calibrating Third-Party Extenders

We are also often asked about connecting third-party extenders to a CMT vector network analyzer. The video below provides a step-by-step guide to connect and calibrate third-party extenders with a Cobalt VNA.

Measuring Device Under Test with a CMT Multiport 9 GHz VNA

Using 4 ports, the new Multiport VNA measures a splitter with limit lines and simultaneously measures a 2-port filter.

Calibrating the Multiport VNA

Senior RF Design Engineer, SME Brian Walker shows how to calibrate the SN5090-16 Multiport VNA for dual measurements.

How to Make High-Frequency Balun Measurements

In this video, we will demonstrate how to use a VNA to make high frequency balun measurements with a CMT VNA.
Adaptive Radome Diagnostic System with 1-Port VNA

Adaptive Radome Diagnostic System with 1-Port VNA

Our integration partner Compass Technology Group’s Adaptive Radome Diagnostic System (ARDS) features in a video about the Air Force ManTech program. The Air Force is able to test the effectiveness of radome repairs, ensuring they are fully operational before taking the aircraft back into the field. This reduces the need to work further on the radome repairs after taking the aircraft out. Keeping the radomes functioning properly is crucial to the safety of the pilots in these aircraft. At time marker 1:48, you can see the ARDS in action with the 1-Port VNA as a part of the system capturing the reflectivity measurements of the radome.

How Do I Access Software and Documentation for my VNA?

If you are looking for software or documentation for your VNA, you can find it in several ways. If you locate your VNA on the website, you can find these items under the software/documentation tab on the product pages. If you hover over the support tab on the navigation bar, you will see pages to Download Software, Download Files, Download Documentation, and about Automation. Watch the video to learn more.

Fixture Characteristic Requirements for Automatic Fixture Removal Plug-in

Brain Walker gives an introduction to automatic fixture removal software plug-in (AFR). He discusses how to use the software, what kind of fixtures are and are not suitable for de-embedding with the software. For this setup, we use a C1220 2-Port 20 GHz VNA, as higher frequency leads to higher resolution with the AFR software. To demonstrate measurements, we use both a high-grade fixture and a homemade fixture with end-launch SMA connectors rated to about 3-6 GHz.
