Features: 2C23T is a fully functional and practical three-in-one digital oscilloscope with two channels launched for the maintenance and development industry. This unit has three main functions: an oscilloscope, a multimeter, and a signal generator. The oscilloscope uses FPGA+MCU+ADC hardware architecture, with a sampling rate of 50MS/s and an analog bandwidth of 10MHz. It is equipped with a built-in high-voltage protection module and can support voltage measurement of up to 400V; Supports saving and viewing waveform screenshots for analysis. The multimeter has a 4-digit 10000 true RMS value and supports AC/DC voltage and current measurement, as well as capacitance, resistance, diode, and other measurement functions. Built-in DDS function signal generator, which can output 7 function signals, with a maximum output of 2MHz for all signals and a step size of 1Hz; The output frequency, amplitude, and duty cycle are adjustable. It uses a 2.8-inch 320x240 resolution high-definition LCD screen, with a built-in 3000mAh rechargeable lithium battery and a standby time of up to 6 hours. Compact size, providing users with more and strong practical functions, while having good portability.
