The Tektronix DF1 is a display formatter for use with the 7D01 logic analyzer. It adds "data domain displays" (binary, octal and hexadecimal state tables, and a function map display) to the 7D01's time-domain display. It can store a reference table, to which the captured data can be compared.
The DF1 is built around a Motorola 6800 microprocessor with two 2K×8 masked ROMs and sixteen 1K×1 SRAMs (2101). It attaches to the 7D01 through a 50-pin D-sub connector on the right side panel.
Project manager for the DF1 was Murlan Kaufman.
