11302
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.
