FNIRSI 2C23T Portable 3-in-1 Oscilloscope Multimeter Signal Generator

FNIRSI 2C23T Portable 3-in-1 Oscilloscope Multimeter Signal Generator

The FNIRSI 2C23T is a versatile 3-in-1 measurement device combining a dual-channel oscilloscope, precision multimeter, and signal generator. Its compact design, intuitive interface, and advanced features make it suitable for both professional and novice electronics engineers. It includes a built-in 3000 mAh lithium battery providing up to 8 hours of operation and a 2.8" color HD screen with 320 x 240 pixel resolution for clear readings in various conditions.

Advanced Dual-Channel Oscilloscope

This device features a dual-channel oscilloscope with a 10 MHz analog bandwidth and 50 MS/s sampling rate. Each channel operates independently to reduce interference and enhance measurement accuracy. The hardware architecture integrates FPGA, ADC, and MCU components to accurately reproduce fine signal details. It supports automatic, single, and normal trigger modes, with one-click automatic adjustment for clear waveform display. Users can save waveform snapshots and export them to a computer for further analysis.

Multimeter with Extensive Measurement Capabilities

The multimeter function measures AC voltage up to 750 V, DC voltage up to 1000 V, current, resistance, capacitance, diodes, and circuit continuity. It also supports zero and phase wire recognition. True RMS measurement and automatic range selection ensure high accuracy and ease of use. The device includes intelligent burnout protection with ceramic fuses for user and device safety. Measurement data can be held on the screen for convenient reading.

Universal Signal Generator

The built-in signal generator produces seven waveform types: sine, rectangular, triangle, full-period pulse, half-period pulse, noise, and DC signals. Output frequency ranges from 1 Hz to 2 MHz, with amplitude adjustable between 0.1 and 3.3 V. The fill factor is adjustable from 0 to 100%, making it ideal for testing and debugging electronic circuits.

Robust Design and User Convenience

The FNIRSI 2C23T is constructed from durable ABS material with an additional silicone cover for enhanced drop and shock resistance. The gold-coated PCB improves corrosion resistance and reliability. A built-in stand allows stable tabletop positioning, and silicone buttons provide comfortable operation. The device charges via a USB Type-C port (5V/1A) and features an ultra-thin profile of 35 mm thickness for easy portability.

Versatile Applications

This device is suitable for workshop and field use. It can measure mains voltage (220 V), analyze impulse signals, measure quartz oscillator carrier waves, evaluate power supply voltage ripple, and test audio signals. It supports five languages: English, Russian, Portuguese, Japanese, and German, with software updates to ensure long-term versatility.
