FNIRSI 2C23T 3-in-1 Handheld Oscilloscope, Multimeter & DDS Generator | 2 Channels, 10MHz, 50MSa/s

Compact, versatile, and field-ready

Meet the FNIRSI 2C23T, a compact 3‑in‑1 handheld instrument that blends an oscilloscope, a digital multimeter, and a DDS waveform generator into one portable unit. Built with an FPGA+MCU+ADC core and a dedicated high‑voltage protection module, this device is designed for on‑the‑go testing, classroom labs, and field service scenarios where space and weight matter.

Key capabilities at a glance

• Two-channel oscilloscope with 10 MHz bandwidth and 50 MSa/s real‑time sampling; 32 KB record depth; maximum measurement voltage of 400 V; automatic measurement features; vertical sensitivity from 200 mV/div to 10 V/div; supports waveform image storage and easy export.
• Multimeter mode covers four digits (0–9999 counts) and a wide range of measurements: AC/DC voltage (0–750 V / 0–999.9 V), DC/AC current (0–9.999 A), resistance (0–99.99 MΩ), capacitance (0–99.99 mF), plus diode test and continuity checks.

Signal generation with flexible waveforms

• Signal generator outputs up to 2 MHz with 1 Hz steps and seven waveforms, including sine, square, triangle, full/half, noise, and DC for diverse test setups.

Design, power, and on‑device workflow

• Robust hardware architecture (FPGA+MCU+ADC) paired with a high‑voltage protection module for safer operation across different environments.
• Bright 2.8" HD LCD for clear waveform viewing, plus a built‑in 3000 mAh rechargeable battery supporting extended field use (standby up to 6 hours).
• Convenient one‑click save and a screening function; saved images can be uploaded to a PC via data cable, enabling easy waveform comparison on the same screen with a reference.

Real‑world use cases

• Education and hands‑on labs where students visualize signals and verify circuit behavior.
• Electronics hobbyists performing quick diagnostics, continuity checks, and component tests on boards.
• Field technicians needing portable, all‑in‑one tools to inspect live circuits with built‑in safety features.
• R&D and prototyping tasks that benefit from on‑device waveform capture and side‑by‑side comparisons against references.

In short, the FNIRSI 2C23T offers a compact, capable toolkit for visualizing signals, validating measurements, and documenting results with exportable images—without locking you into multiple devices or complex setups.
