[SI-LIST] Re: VNA/VSA question

A scalar (regular) network analyzer provides only power vs. frequency
information.  If you wish to measure a parameter that requires phase
information (complex reflection coefficients, VSWR, etc) or you want any
type of time-domain conversion, a vector network analyzer is required.  A
VNA is also better at calibrating out connectors, so it provides a more
accurate picture...especially if you're dealing with a sophisticated DUT.

What are the advantages of using a Vector Spectrum or Vector Network
Analyzer over a regular spectrum/network analyzer? What tangible
enhancements can I perform in the lab with the vector feature? Thanks in
advance Hans Mellberg
