FNIRSI® 2C53T 50MHz 250MS/s Handheld 3in1 Oscilloscope Multimeter Signal Generator

🧾 Product Description

The FNIRSI-2C53T is a powerful 3-in-1 dual-channel digital oscilloscope, combining the features of an oscilloscope, a multimeter, and a signal generator — all in one compact device. Designed for technicians, engineers, students, and electronics hobbyists, it’s perfect for research, troubleshooting, and lab work.

Built with FPGA + ARM + ADC hardware architecture, it offers a sampling rate of 250MS/s and a 50MHz analog bandwidth, ensuring high accuracy and performance. The oscilloscope supports ±400V peak voltage, waveform saving, and viewing for detailed analysis.

Its 4.5-digit True RMS multimeter can accurately measure AC/DC voltage, current, resistance, capacitance, diode, temperature, and continuity, making it a complete measurement solution.

The DDS function generator outputs 13 waveform types (sine, square, sawtooth, etc.) with frequencies up to 50KHz, and allows users to adjust amplitude and duty cycle easily.

Equipped with a 2.8-inch color LCD display, rechargeable 3000mAh lithium battery, and Type-C charging, the FNIRSI-2C53T offers excellent portability and up to 6 hours of use on a single charge.
