## Summary description

Fnirsi 2C53T is a portable 3‑in‑1 instrument combining an oscilloscope, multimeter and signal generator in one device. Designed for electronic testing, troubleshooting and measurements, it offers multi-function convenience for hobbyists and technicians. Suitable for inspecting waveforms, measuring voltages/currents and generating test signals for circuit diagnostics and repairs.

## Long description

The FNIRSI 2C53T is a portable 3‑in‑1 instrument combining a two‑channel oscilloscope, a digital multimeter and a signal generator in a single handheld unit. It provides 50 MHz analog bandwidth per channel, 250 MSa/s sampling, an 8‑bit ADC with 16 kpoints memory buffer per channel (pre/post‑trigger), and a built‑in signal generator up to 50 kHz. The device features 1 MΩ ∥ 15 pF input impedance with AC/DC/GND coupling, a 2.8‑inch 320×240 color display, rugged ABS housing with silicone overlays, and an internal rechargeable battery for mobile use. Safety features include CAT II 300 V certification, dual ceramic fuses and an overvoltage protection circuit. Waveform saving and firmware updates are supported.
Advantages
The unit integrates oscilloscope, multimeter and function generator capabilities into one compact, battery‑powered enclosure for field and bench use. A professional ARM+FPGA+high‑performance ADC architecture enables fast triggering and accurate waveform reproduction. Dual isolated channels reduce interference between inputs, while the color display with persistence modes and multiple timebase/trigger options facilitates clear observation of signals and phase relationships. Built‑in protections, durable mechanical design and the ability to export waveform images or save screenshots make the instrument practical for a wide range of measurement tasks.
Suitable for
Electronic troubleshooting and circuit debugging
Repair and maintenance of power supplies and converters
Testing filters, amplifiers and analog circuits with the built‑in signal generator
Portable field measurements and educational laboratory work

How to use
Connect the relevant probes for oscilloscope or multimeter measurements and select the required input coupling and vertical/horizontal scales on the device. Use the AUTO function for automatic range and trigger setup when observing unknown signals, or choose Manual/Single/Normal trigger modes for controlled captures. Configure the signal generator waveform, frequency, amplitude and offset to stimulate the circuit under test. Save waveform images or data to internal memory or transfer them to a computer via USB for further analysis. Observe safety limits and the device’s maximum measurement voltage when probing live circuits.
Usage recommendations
Use standard 10× oscilloscope probes for high‑voltage or high‑frequency signals when appropriate, verify input coupling before measurement, and adhere to CAT II 300 V limits and general safety practices. For longer measurement sessions, charge the battery between uses and update firmware when new releases are available to maintain device functionality.
