The DF2 does not, however, have a GPIB interface of its own − it can only analyze it. This functionality is invoked with the added MENU control (refer to the instruction manual for details).
Project manager for the DF2 was Murlan Kaufman.
A 103-0209-00 GPIB to probe comb adapter was supplied with the DF2.
