FNIRSI 2C53T 3-in-1 Handheld Oscilloscope, Multimeter & Signal Generator

Product Description

The FNIRSI 2C53T 3-in-1 Handheld Oscilloscope is a multifunctional electronic test instrument that combines a dual-channel digital oscilloscope, a digital multimeter, and a DDS function signal generator in one compact device. Designed for electronics technicians, engineers, repair workshops, and laboratory applications, it provides three essential measurement and testing functions without requiring separate instruments.

The oscilloscope features a 50MHz analog bandwidth and a maximum real-time sampling rate of 250MSa/s, allowing users to capture and analyze electrical waveforms across two independent channels. It provides a 1Kpts storage depth, adjustable vertical sensitivity from 10mV/div to 10V/div, and a time base range from 10ns/div to 20s/div. Additional functions include AC/DC coupling, rising-edge and falling-edge triggering, Auto, Normal, and Single trigger modes, and Y-T, Rolling, and X-Y display modes.

For more detailed waveform analysis, the 2C53T supports cursor measurements, eight basic mathematical operations, FFT analysis, waveform persistence, and automatic measurements. Users can also capture waveform screenshots, save them, and export the images to a computer through the USB Type-C interface.

The integrated 4½-digit digital multimeter provides 20,000-count True RMS measurement capability. It supports AC and DC voltage, AC and DC current, resistance, capacitance, temperature, diode testing, and continuity testing. Its measurement ranges include DC voltage up to 1000V, AC voltage up to 750V, and current up to 9.999A, making it suitable for a wide range of electronic and electrical troubleshooting tasks.

The third function is a built-in DDS signal generator capable of producing 13 waveform types, including sine, square, sawtooth, half-wave, full-wave, step, exponential, DC, and other specialized signals. Its output frequency ranges from 1Hz to 50kHz, with adjustable amplitude and duty cycle, making it useful for testing amplifiers, filters, signal-processing circuits, and electronic prototypes.

The instrument features a 2.8-inch color LCD with 320 × 240 resolution, providing a clear display for waveforms and measurement readings. It is powered by a built-in 3000mAh rechargeable lithium battery, with a stated standby time of up to six hours under laboratory conditions. USB Type-C charging and its handheld construction make it suitable for portable testing and field diagnostics.
