FNIRSI 2C53P 3-in-1 Oscilloscope, Multimeter & Signal Generator Case

Description

Product Overview

The FNIRSI 2C53P is a 3‑in‑1 handheld instrument that merges a dual‑channel oscilloscope, a high‑resolution digital multimeter, and a DDS signal generator into a single compact tablet. Built on a robust FPGA‑MCU‑ADC architecture, the device delivers a 50 MHz bandwidth and a 250 MS/s real‑time sampling rate, ensuring accurate capture of fast‑changing waveforms. The 4.3‑inch IPS touchscreen provides a 480×272 pixel display, delivering crystal‑clear waveforms and intuitive navigation. A built‑in 4000 mAh lithium‑ion battery supplies up to four hours of continuous operation, while the high‑voltage protection module safeguards the instrument against accidental over‑voltage exposure up to ±400 V.

Usage

This versatile tool is designed for automotive technicians, electronics hobbyists, and field engineers who need reliable measurements on the go. Use the oscilloscope mode to diagnose engine control unit signals, monitor PWM outputs, or troubleshoot power supply ripple. Switch to multimeter mode for precise voltage, current, resistance, capacitance, diode, continuity, and temperature readings, making it a one‑stop solution for routine maintenance. The DDS signal generator creates sine, square, triangle, pulse, noise, and DC waveforms up to 10 MHz, perfect for testing audio circuits, communication links, and sensor calibrations.
