• Test Station Delivered to NAVSEA NSWC
  5/8/2010 9:48am

  We delivered a Test Station to NAVSEA Naval Surface Warfare Center (NSWC) in Crane, Indiana. The Test Station contains many state of the art features, including: The latest Agilent Network Analyzer (PNA-X Series) A 10-port Extension for measuring multi-port S-parameters An R. A. Wood Associates custom-designed RF Load Box/Chassis for testing high power RF devices Rack mount conputer, keyboard, and monitor with digital I/O, GPIB interfaces A PXI chassis with fiber optic interface, digital I/O, serial interfaces, temperature monitors, and GPIB interfaces LabVIEW Software utilities to support setting up the Network Analyzer, retrieving S-parameters from the Network Analyzer, controlling the RF Load Box, and controlling other measurement equipment in the Test Station This was a very exciting project, and we really enjoyed working with our customer on this program. The complete project was delivered within 7 months of the order being placed. Great job everybody!

• mmW Equalizers Designed and Built for our Customer
  4/5/2010 5:55pm

  One of our customers had a need for a mmW equalizer to help offset a 7 dB negative slope across a 26.0 to 40.0 GHz band. We looked far and wide to see if there were any available components out there in the industry that we could buy as an off-the-shelf part, or have someone develop for us. We could not find any available parts. So we took on the task ourselves to design a mmW equalizer with a 7 dB positive gain slope. This is just another example of how we can break new ground to come up with designs that are needed by our customers when they are not otherwise available. The equalizer was installed in the system, and the 7 dB negative slope was flattened out. See before and after pictures below. Another exciting success story!

• Painless Extraction Scriptor 1.0 Released
  3/26/2010 10:42am

  We have released a new Software Product, called Painless Extraction Sciptor (Version 1.0). This program combines the data extraction and analysis capabilities of Painless Extraction & Painless Extraction Noise Figure with a new Custom Dialog Utility and an External Program Caller in an easy to use interface to automate testing through scripting. This program enables the user to construct script files that will call Painless Extraction, Painless Extraction NF, Custom Dialog Boxes, and External Programs. Use these capabilities in combination to create customized automated testing procedures. For more information, please visit our software download page.

  Now you can automate Network analyzer, Scalar Analyzer, and Noise Figure measurements, and automatically create test reports for production testing! The custom dialog boxes can be used to guide test personnel through the testing process. External programs can be used to control devices prior to collecting measurements from the test equipment. We'll be providing more documentation about this program through our various software and support wiki's.

• New Update (2.2) for Painless Extraction Released
  3/22/2010 9:10am

  We've released a new version of Painless Extraction (2.2) today. This release includes many new features, including:

  • Compatibility with HP 8575d Scalar Analyzers
  • Compatibility with new Agilent PNA Network Analyzers (will be released in Version 2.2.1 very shortly)
  • A new graphical interface panel with plots, statistics, and a pass/fail report, all on the same page
  • Capability to be called from Painless Extraction Scriptor, which will allow Painless Extraction to be called remotely from script files (stay tuned for the release of Painless Extraction Scriptor coming soon)
  • A self contained macro capability, where multiple plots can be printed with limits. A great way to create a quick test report for each part tested.

  Please feel free to visit our software information page for more information. As always, your feedback and suggestions are always welcome!

• SpurFinder 3.5.2 Update Released
  10/6/2009 2:17pm

  We've updated SpurFinder to version 3.5.2. This update fixed a user interface bug: When the program was initially opened, the "Continuous Run/Single Run" selector was hidden from the user interface. This selector didn't reappear until the user opened a "Multi Scenario Script File" from the file menu, and then closed the file. This may have caused some confusion in using the program, which we apologize for. The update is free and can be obtained by downloading the SpurFinder installation files from our Software Download Page. Previously registered software will still be registered during the installation.
