FNIRSI 2C53P Portable 3-in-1 Oscilloscope 50MHz 250MSa/s

FNIRSI 2C53P 4.3-inch Portable 3-in-1 Touchscreen Oscilloscope

The FNIRSI 2C53P is a compact, portable device combining three essential functions: a dual-channel oscilloscope, a digital multimeter, and a DDS signal generator. It features a 4.3-inch IPS touchscreen with a resolution of 480 x 272 pixels, enabling intuitive operation and flexible waveform viewing with zoom and pan capabilities. The oscilloscope supports a bandwidth of 50 MHz, a sampling rate of 250 MSa/s, and offers 12 selectable waveform types, making it suitable for precise measurements of voltage, current, resistance, capacitance, and temperature with up to 19999 readings.

Advanced Signal Analysis Features

This oscilloscope provides professional-grade signal analysis including FFT (Fast Fourier Transform), X-Y mode, cursor measurements, mathematical functions, and True RMS measurement. It supports three trigger modes: automatic, normal, and single. The auto set function allows quick waveform calibration with a single button press. Additionally, a bandwidth limiting function up to 20 MHz enables accurate measurement of power supply interference at millivolt levels.

High-Precision Multimeter with Safety Features

The integrated multimeter measures AC/DC voltage, current, resistance, capacitance, diodes, continuity, and temperature with high accuracy (up to 19999 readings). It can store up to five measurement parameters, track minimum and maximum values, and export data to a computer via USB. Dual ceramic fuses protect the device from current and voltage overloads, ensuring safe operation.

Robust Design and Fast Charging

Equipped with a 4000 mAh lithium battery, the FNIRSI 2C53P offers extended operation without frequent recharging. The device features a tempered glass screen, an adjustable stand with 90° tilt, and a compact, impact-resistant housing suitable for both workshop and field use. The interface supports eight languages: Chinese, English, Russian, Japanese, Spanish, Portuguese, German, and Korean.

Versatile Applications

This oscilloscope is ideal for measuring 220 V mains voltage, switching power supplies, power supply interference, pulse signals, and audio signal analysis. It is a versatile tool suitable for professional laboratories and hobbyists alike.
