FNIRSI 2C23T 3-in-1 Portable Oscilloscope Multimeter Signal Generator
FNIRSI 2C23T is a compact 3-in-1 portable measuring device that combines a dual-channel oscilloscope, precision multimeter, and signal generator in one lightweight housing. Equipped with a 10 MHz oscilloscope, 50 MS/s sampling rate, and a built-in signal generator with frequencies up to 2 MHz, it is ideal for electronics diagnostics, circuit testing, and field measurements. The 2.8-inch color display ensures clear waveform visualization, while the 3000 mAh rechargeable battery provides up to 8 hours of operation. Its durable ABS housing with silicone protection makes it suitable for both workshop and mobile use.
The integrated oscilloscope features two independent channels with a 10 MHz bandwidth and 50 MS/s sampling rate, ensuring accurate waveform capture and reliable signal analysis. The FPGA + ADC + MCU architecture improves signal processing precision and reproduces waveform details with high stability. Automatic, single, and normal trigger modes allow flexible operation for different measurement scenarios, while automatic waveform adjustment simplifies setup for quick diagnostics. Captured waveforms can be saved and exported to a computer for further analysis and documentation.
The built-in multimeter supports AC voltage measurements up to 750 V and DC voltage up to 1000 V, along with current, resistance, capacitance, diode, continuity, and live/neutral wire testing. True RMS functionality and automatic range selection improve accuracy and simplify operation. Integrated ceramic fuse protection enhances safety during demanding measurements.
