Signal Sources - Understanding How to Best combine Sources for TOI Measurement
An overview of how a TOI measurement is made and an explanation of the benefits of using either power splitters or directional couplers in the test set up.
About this course
Third-order intermodulation is a key receiver linearity measurement made using two signal sources. In setting up this test it is critical that these signals are combined in a manner which minimizes the products produced by the sources, ensuring a more accurate measurement of your DUT. An overview of how the measurement is made, along with considerations for the measurement receiver (ie spectrum analyzer). In addition, an explanation of the benefits of two key combination methods using power splitters and directional couplers is made. Making the effort to best set up your sources for TOI testing will enable you to accurately test your designs or products.
