The '''Tektronix 2440''' is a two-channel 300 MHz, 500 MS/s digital sampling oscilloscope from the late 1980s.
The maximum sample rate is 500 megasamples per second, per channel.
 
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.

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.
