The Tektronix 2440 is a two-channel 300 MHz, 500 MS/s digital sampling oscilloscope from the late 1980s.
It uses CCDs (essentially, analog shift registers) to store input samples at high speed and a single 8 bit flash A/D converter to digitize the time-multiplexed CCD output signals at 4 MS/s.
WARNING:
Operation of the 2440 (and 2432 and 2430): A/D-converter and CCD hybrids may suffer irreparable damage within a few minutes if operated out of the metal enclosure without extra cooling.

Internals
The 2440 employs several processors − an MC68B09 main CPU controls the instrument, a custom 16-bit waveform processor performs signal computations, and an MC6805 microcontroller handles the front panel interface. The GPIB Interface is implemented with a TMS9914 controller.
The power supply consists of a buck-type pre-regulator followed by a push-pull inverter and linear post-regulators (except for the +5 V digital supply rail).
CRT is a 154-0850-01.
