Page 5 - App Notes

CMT VNAs are USB-based and do not have built-in computers. There are a few benefits to having the VNA measurement module separate from the processing module. When they are separated, the user isn’t stuck with an obsolete built-in PC in a few years. It also means that the VNA can be smaller in size, making it more lightweight and portable.

This application note provides information on Automotive Ethernet, full-duplex communication, the need to separate master and slave signals, signal separation testing methodologies, and a comparison of the current directional coupler insertion method and the Tektronix new signal separation method.

This app note examines the theory of state-of-the-art spectrum analysis and describes how modern spectrum analyzers are designed and how they work. That is followed by a brief characterization of today's signal generators, which are needed as a stimulus when performing amplifier measurements.
