DF2
The Tektronix DF2 is a display formatter for use with the 7D01 logic analyzer.
It is a DF1 with special support for debugging GPIB, from which it differs by having an extra front-panel "MENU" key and a daughter board with additional ROMs.
The DF2 does not, however, have a GPIB interface of its own − it can only analyze external GPIB traffic. 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. This connects GPIB DIO1..DIO8 to CH8..CH15, DAV to the CLOCK input, ATN to CH7, EOI to CH6, SRQ to CH5, and REN to CH4. GPIB signals DAV, NRFD, NDAC and IFC brought out to pins on the connector. CH3..0 are user defined inputs that can track any of these signals, or others as needed. For GPIB analysis, bus data is acquired synchronously using the negative-going edge of the GPIB DAV (Data Valid) line as an external clock.
