HP 8601A GENERATOR / SWEEPER
 
 
 
The 8601A is a general purpose Generator and Sweeper, but bought specifically for use with the 8407A Network Analyser.  The original cost was $3,300 in 1980.  A HP Manual was downloaded from the Web.  The serial number is much later than the downloaded HP Manual so several assemblies are different.
