FNIRSI 2C23T High-Precision Portable Digital Measuring Instrument, 3-in-1 Oscilloscope + Multimeter + Signal Generator

This is a fully-featured, highly practical 3-in-1 dual-channel digital oscilloscope designed for the maintenance and development industries. This device combines three main functions: oscilloscope, multimeter, and signal generator. The oscilloscope uses an FPGA + MCU + ADC hardware architecture and boasts a 50 MS/s sampling rate, 10 MHz analog bandwidth, and a built-in high-voltage protection module that can support peak voltage measurements of up to ±400 V. The function signal generator can output seven types of function signals with a maximum output of 2 MHz. The output frequency, amplitude, and duty cycle can be adjusted to suit various needs. It features a built-in 3000 mAh rechargeable lithium battery, providing up to 6 hours of long standby time.
