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 CD output signals at 4 MS/s. | |||

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 TMS994 controller. | |||
