The FNIRSI 2C23T is a versatile 3-in-1 measuring device that combines the functions of a two-channel oscilloscope, a precision multimeter and a signal generator. With its compact design, intuitive handling and advanced functions, it is an ideal choice for both professional and novice electronics engineers. The built-in 3000 mAh battery provides up to 8 hours of operation time, and the 2.8" color screen with a resolution of 320 × 240 px allows comfortable reading in any conditions.
The device offers a two-channel oscilloscope with a bandwidth of 10 MHz and a sampling rate of 50 MS/s. Both channels work independently, which eliminates interference and increases measurement accuracy. Thanks to the thoughtful hardware architecture (FPGA + ADC + MCU), the FNIRSI 2C23T perfectly reproduces even the smallest details of the signals. It supports automatic, one-time and normal triggering modes and allows you to change settings automatically - you can get a clear graph with one click. You can save and export waveform snapshots to a computer for easy analysis later.
The functions of the multimeter allow accurate measurement of voltage (alternating current up to 750 V, direct current up to 1000 V), current, resistance, capacitance, diodes, circuit continuity, as well as neutral and phase wire recognition. True RMS measurement and automatic range selection ensure high accuracy and ease of use. Intelligent burnout protection (using ceramic fuses) protects the device and the user. Measurement data can be saved on the screen for easy reading and interpretation.
The built-in generator offers seven types of signals, including sine, square, triangle, full period, half period, noise and DC signals. The output frequency ranges from 1 Hz to 2 MHz and the amplitude ranges from 0.1 to 3.3 V. The user can also set the fill factor between 0 and 100%. It is an ideal tool for testing and debugging electronic circuits.
The FNIRSI 2C23T is made of durable ABS material with additional silicone coating for drop and impact resistance. The high-quality gold-plated PCB ensures better corrosion resistance and reliable operation. The comfortable stand allows for stable placement on the table, and the silicone buttons ensure comfortable handling. The USB-C port enables fast charging, and thanks to the ultra-thin (only 3 cm thick) design, the device fits easily in a bag or backpack.
The FNIRSI 2C23T proves useful both in the workshop and in the field. It is capable of measuring 220V mains voltage, analyzing pulse signals, measuring the carrier wave of quartz oscillators, evaluating the voltage ripple of power supplies and examining audio signals. Support for five languages (English, Russian, Portuguese, Japanese, German) and software updates ensure the versatility and longevity of the equipment.
