ANALYZER
The 681XXC signal generator is compatible with the Anritsu Model
360B VectorNetwork Analyzer (VNA). The following paragraphs pro-
vide instructions for connecting the 681XXC to the 360B VNAand con-
figuring the signal generator so that it can operate as a signal source
for the analyzer.Operating instructions for the vector network ana-
lyzer can be found in the Model 360B VectorNetwork Analyzer Opera-
tion Manual, P/N 10410-00110.
