+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.
+<blockquote>
+'''WARNING:'''<br />
+Operation of the 2440, 2432, 2432A, 2430, and 2430A: 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 [[Motorola 6809|MC68B09]] main CPU controls the instrument, a custom 16-bit waveform processor performs signal computations, and an [[Motorola 6805|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]].
