11301

The Tektronix 11301 is a programmable 400 MHz analog oscilloscope that takes up to three 11000-series plug-ins or (vertical) 7000-series plug-ins. Note, however, that the 7000 series plugins have mechanical interlock preventing them from being installed into an 11K mainframe.

The sister model 11302 is basically identical but has a micro-channel plate CRT and 500 MHz bandwidth.

The 11301 has an infrared beam touch screen. There are 10 columns and 14 rows of beams.

The 11301 and 11302 make use of a patented system for automatically calibrating all the way to the graticule (i.e., including CRT deflection sensitivity) by optically sensing the position of the beam with respect to the graticule and applying any necessary correction factors. This is discussed in the patent and also on page 9 of the Handshake article linked below which states:

Optical sensors on the CRT bezel sense when the beam crosses the graticule lines to factor this information into the auto cal control signals. As a result, accuracy of the 11300-Series is controlled from the plug-in input connector to the CRT graticule without operator intervention.
