The signal is first measured, then measured again with a phase shift of 180 degrees.
#DSA815 CORRECTION FACTORS GENERATOR#
Starting with a properly calibrated machine, Ted uses a small board he built to electronically shift the phase of the Tracking Generator where the leakage is a problem. The solution is based on phase shifting the measurement. Ted found a simple technique that can correct for the leakage. Spectrum Analyzers with Tracking Generators (SA/TG) have come onto the market, but especially with early versions, there is a leakage problem that causes inaccuracy. This task is often reserved for Vector Network Analyzers (VNA) but with a heafty price tag these tools aren’t available to everyone. In his work, Ted finds an interesting opportunity to get more performance out of relatively inexpensive bench equipment used to characterize RF components. We applaud him, and the peer reviewers, for the attention to detail while moving toward publication. The title of Ted’s paper is a mouthful and the subject material wades into radio frequency knowledge with gusto.

Do not hesitate to get in touch with us about topics you want to write about. You should not need to be working on a degree to have your findings published, but of course students and faculty are encouraged to submit their papers. We are in an age of unparalleled opportunity for individuals and small teams to make interesting discovery. But for that to happen we need you to share your knowledge.
#DSA815 CORRECTION FACTORS FULL#
The full name of our journal is the Hackaday Journal of What You Don’t Know - it will be a tome of infinite appeal to any who seek to broaden their minds in the engineering space.

Please consider authoring a paper on any creative research, engineering, or entertaining discovery in the areas of interest to the Hackaday community. We have other submissions in the pipleline now but we still need more papers to round out the first volume of the Hackaday Journal. Before jumping into Ted’s topic, please take a moment to consider submitting your own paper for the journal. The Hackaday Journal is an open access, peer reviewed journal that seeks to ensure hard-won domain knowledge is preserved and made available for the benefit of all. You can read the standalone paper here it will be included in the first volume of the Hackaday Journal officially released later this year. Congratulations and thank you go to Theodore Yapo for authoring the first paper to complete the peer review process for the Hackaday Journal.
