HP 8601A GENERATOR SWEEPER
The HP 8601A Generator Sweeper is a general purpose Generator and Sweeper, but bought specifically for use with the HP 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.
