Overview
The FNIRSI 2C53T is a high-performance 3-in-1 handheld instrument designed for the modern engineer. It combines a 50MHz dual-channel oscilloscope with a 250MSa/s sampling rate, a high-precision digital multimeter, and a DDS signal generator. Featuring a 4.3-inch high-definition colour touchscreen, it offers a smartphone-like user experience while providing the rugged reliability needed for industrial environments.
Key Features
3-in-1 Functionality: Seamlessly switch between Oscilloscope, Multimeter, and Signal Generator modes with a single tap.
Dual-Channel Scope: Monitor two signals at once—essential for analyzing input/output timing and phase shifts.
Precision Multimeter: Measures AC/DC voltage, current, resistance, capacitance, diode, and continuity with auto-ranging.
DDS Signal Generator: Output 12 types of waveforms (up to 10MHz for sine) to simulate sensors or clock signals.
Touch & Button Control: Use the responsive touchscreen for fast navigation or physical buttons for precise adjustments when wearing gloves.
Internal Storage: Save and view waveforms or multimeter data directly on the device for quick troubleshooting.
