7D01
The Tektronix 7D01 is a 16-channel logic analyzer plug-in for the 7000-series scopes. It can be used by itself, or with a DF1 or DF2 display formatter that attaches to the left of the 7D01 through a DD-50 connector. When used standalone, it displays a timing diagram, and uses the mainframe's readout system to indicate the cursor position (on top) and the binary data pattern at the cursor location (using the two bottom readout fields).
The 7D01 takes two P6451 8+1 channel probes. It does not contain a microprocessor and is built entirely from off-the-shelf ECL and TTL logic ICs.
The 7D01 is also compatible with the DL2 or DL502 latch (glitch detector). It has an internal DB-25 data output connector and a front-panel cut-out for the corresponding cable.
Project manager for the 7D01 was Murlan Kaufman.

Notes
Note about external clock rates (from Jim Mauck):
When I was a Tek Service Technician I worked on the 7D01. For several years I tested every 7D01 I worked on (and that was a lot of them) with a 100 MHz external clock in 16 channel mode. I would use a DF2 and set it to reacquire continuously as long as the 7D01 memory was the same as the original data I stored into the DF2 memory. The analyzer would run for hours without error. The funny part is that it wasn't until I had been doing this for several years that I realized it wasn't specified to run at that frequency. I continued to test them that way even after I discovered my error. However the instrument exceeding the specifications might be due to the data source providing a generous setup and hold time relative to the active clock edge.
