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 11301A update was introduced in 1989.
The 11301 and 11302 make use of a patented system for fully calibrating the instrument from the input BNC to the graticule by optically sensing the position of the beam with respect to the graticule during calibration. 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. The 11300-Series is thereby calibrated from the plug-in input connector to the CRT graticule.
The 11300 scopes have an infrared beam touch screen. There are 10 columns and 14 rows of beams.

Internals
The 11301 contains a 77 nanosecond delay line.
There are two replaceable batteries internal to the 11300 series oscilloscopes. Both batteries are CR123 (aka A123) 3.0V lithium types. The 11300 series scopes use a battery holder, and battery replacement is straight forward.
One battery is located on the main processor board which is mounted on the top of the chassis. Remove the top cover and this battery is immediately visible. It holds user data and information from the last successful calibration cycle. This data will be replaced in the next calibration cycle.
A second battery is located on the Memory Expansion board which is also located on the top of the chassis. This battery maintains only user data such as instrument setups, stored waveforms and text.
Factory calibration constants are held in EEPROM and are not affected by battery replacement or failure.
