The 89600S custom vector signal analyzer allows you to customize the 89600 Series of PC-based vector signal analyzers to meet your needs. This piecewise ordering approach allows you to purchase all the components required to, for example, substitute a 6- or 13-slot VXI mainframe instead of the 4-slot mainframe provided in the 89610A or 89640A bundle. This is required if you want to include other VXI modules or put both a baseband and RF VSA system in one mainframe. All of the 89600 family features and benefits are available in the 89600S custom vector signal analyzer.
