1. Voltage Reference Voltage reference U31 generates an accurate reference that is used by the DMM circuits The 2 5 V output is divided with four resistors to supply the needed reference voltages DMM Isolation lt gt The DMM is isolated from the rest of the main board The digital signals are coupled through opto couplers Power is transformer coupled from the isolated power supply lt gt The CPU system contains 68331 microprocessor U6 that controls all oscilloscope DMM and display activities CPU Clock Processor clocks are derived from the 30 303 MHz oscillator that drives the sampler U7 and display controller IC U21 The display controller IC divides the 30 303 MHz clock by two for a processor clock of 15 15 MHz Interrupts The 68331 supports seven levels of auto vectored interrupts dedicated to different interrupt levels The sampler display system and DUART generate interrupts Reset The CPU resets both at power on and power off using the reset signal Reset controller U3 controls system reset Power on reset asserts after the 5 V supply stabilizes Power off reset asserts when the supply falls below a usable threshold Memory The memory subsystem includes flash ROM for power off storage and processor firmware The memory system also includes dynamic RAM for use as system RAM The flash ROM U1 isa 1 MB 8 device that provides nonvolatile storage of front panel settings waveforms and calibration con
