TEST AND MEASUREMENT APPLICATION NOTES AND WHITE PAPERS
Measure Group Delay Without LO Access
In order to operate in a satisfactory matter, a mixer needs to have well controlled amplitude, phase response, and group delay. Constant group delay is especially important in wireless and satellite communications systems and in applications involving high target resolution in surveillance systems. When mixers are used to measure group delay in frequency converters, some setbacks can occur if the local oscillator isn’t accessible...
Multi-Tone Testing Can Save Both Time And Money This article describes a patented multi-tone testing process that allows users to test multiple tones per dwell period in order to increase test efficiency by a factor approximately equal to the number of tones tested. The multi-tone concept’s history is covered, along with information on its effectiveness, and information on potential future applications.
The Y Factor Technique For Noise Figure Measurements This application note describes in detail the steps required to make a noise figure measurement on a spectrum analyzer using the “Y Factor” technique.
