11201
The Tektronix 11201 is a 400 MHz sampling oscilloscope. It does not take plug-ins, but it is electrically similar to the 11401 with two 11A32 plugins and uses the same firmware. The 11201 is specified to have nine bits of vertical resolution whereas the 11401 and 11402 are specified to have ten bits of vertical resolution.
David White was the project manager for the 11201.
Key Specifications

Internals
The 11201 has a card cage containing five boards:
- I/O Board (A14)
- Memory Management Unit Board (A15)
- Compressor Board (A16)
- Main Processor Board (A17)
- Memory Board (A18)
The five boards plug into the card cage interconnect, which is completely passive. All card cage interconnect connectors have 96 pins and are wired identically. The connectors have three rows of 32 pins each and resemble VME connectors.
The main microprocessor for the 11201 is an Intel 80286 with an 80287 math co-processor.
