The Sencore SC3100 is a 100 MHz dual-trace oscilloscope and circuit analyzer combining waveform measurement with integrated digital metering for comprehensive circuit troubleshooting. The AUTO TRACKER feature automatically selects optimal timebase and vertical scaling, displaying approximately 2–5 cycles of the input signal without manual range adjustments. A microprocessor-driven LCD display provides direct digital readouts of voltage, frequency, resistance, and dBm values from a single probe connection.
