Unlock professional-grade diagnostic power in the palm of your hand with the FNIRSI 2C23T / 2C53T Upgrade Handheld Digital Oscilloscope Multimeter Signal Generator 3-in-1. Designed for engineers, technicians, electronics hobbyists, and automotive experts, this compact yet powerful device combines three essential tools into one intelligent testing solution—oscilloscope, true RMS multimeter, and DDS signal generator.

Built with advanced FPGA + MCU + high-speed ADC architecture and equipped with ±400V high-voltage protection, the FNIRSI handheld series delivers safe, accurate, and reliable performance in any environment—from workshop repairs to field diagnostics.

The 2C23T model offers a 50MS/s sampling rate with 10MHz bandwidth, perfect for general electronics troubleshooting and education use. Meanwhile, the upgraded 2C53T version boosts performance dramatically with 250MS/s sampling and 50MHz bandwidth, capturing faster and more complex waveforms with precision.

Enjoy crystal-clear visualization on the 2.8-inch 320×240 HD display, with intuitive Y-T / scroll modes, waveform saving, and screenshot export. The built-in 3000mAh rechargeable battery provides up to 6 hours of standby time, making it ideal for mobile repairs and on-site diagnostics. Charging is fast and convenient via USB Type-C (5V/1A).

As a multimeter, it supports wide-range measurements including AC/DC voltage, current, resistance, capacitance, temperature (-55°C to 1300°C), diode testing, continuity check, and live wire detection. The 2C53T further enhances precision with true RMS 4.5-digit accuracy (19999 counts).

The integrated DDS signal generator offers multiple waveform outputs (sine, square, triangle, pulse, noise, and more), with adjustable frequency, amplitude, and duty cycle—perfect for circuit testing and signal simulation.

Whether you're debugging automotive electronics, repairing household devices, learning electronics, or working in R&D labs, the FNIRSI 3-in-1 handheld tester delivers portability, accuracy, and professional performance in one device.
