The Tektronix 11302 is a 500 MHz analog oscilloscope with a micro-channel plate CRT that can operate with 11000-series plug-ins or 7000-series plug-ins. Note, however, that the 7000 series plugins have mechanical interlock preventing them from being installed into an 11K mainframe. The 11302 includes a 500 MHz (11302A: 750 MHz) counter/timer.

Except for the MCP CRT, the 11302 is basically the same as the 400 MHz 11301.

The 11302A version increased external counter input bandwidth to 750 MHz and added a readout mode button.

The 11302 contains a 77 nanosecond delay line.

Full calibration of an 11302 requires the use of the TEKCATS software.

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.
