FNIRSI 2C53P 3-in-1 Handheld Oscilloscope, Multimeter & Signal Generator, 50MHz 250MSa/s Dual Channel Digital Oscilloscope with 4.3" Touch Screen

This FNIRSI 2C53P is a versatile 3-in-1 test instrument tailored for electronics technicians, hobbyists, and engineers, designed to meet diverse testing needs in maintenance, R&amp;D, and educational settings. <br> At its core, the oscilloscope features a dual-channel design with 50MHz analog bandwidth and 250MSa/s real-time sampling rate, delivering crisp, stable waveform displays with 8-bit vertical resolution. It supports multiple trigger modes, waveform math calculations, and a 20MHz bandwidth limit for power supply ripple testing. Built-in high-voltage protection ensures safe operation with up to ±400V peak voltage input, while waveform screenshot and computer export functionality enable seamless data sharing and secondary analysis. <br> The integrated true RMS multimeter offers 19999 counts resolution, covering a full range of electrical measurements: AC/DC voltage/current, resistance, capacitance, temperature, diode, and continuity tests, suitable for both basic troubleshooting and advanced circuit validation. <br> Completing the triple-function design, the DDS signal generator outputs 12 types of waveforms (including sine, square, sawtooth, and DC signals) with adjustable frequency (up to 10MHz for sine waves), amplitude, and duty cycle, allowing users to simulate custom signals for circuit testing and prototyping. <br> With a 4.3-inch IPS touch screen (480*272 resolution) and tempered glass surface, the device provides intuitive, responsive operation even in bright environments. Powered by a 4000mAh lithium battery, it delivers up to 4 hours of continuous use, and Type-C charging ensures convenient power replenishment via common adapters. The compact 145x98x35mm size and 360g weight make it highly portable, ideal for on-site repairs, lab work, and classroom use. Multi-language support ensures accessibility for users worldwide.
