Internals
The 2424L uses a Motorola 68B09 microprocessor and a TMS9914 GPIB controller. Like in the 7D20, the ADC uses an analog shift register (CCD) for high-speed signal acquisition, and then digitizes the stored analog signal at a lower speed (see Patent US 4527117A). The front panel has its own 6805 microcontroller.
Proprietary ICs in the 2424L include:
