What the project implements is a handheld dual-trace pocket oscilloscope, with TMS320F28033 as the core, consisting of signal amplification circuit, signal acquisition circuit, data storage and processing module, system control and display module, etc. The signal amplification circuit first performs program-controlled gain amplification on the input signal. The signal acquisition circuit uses a high-speed ADC to convert the signal from analog to digital, and the data is sent to the data storage and processing module with FPGA as the core. TMS320F28033 controls the LCD display and touch input. The system has the characteristics of small size, small input impedance and low power consumption.
