FNIRSI-2C23T & 2C53T are advanced 3-in-1 dual-channel digital oscilloscopes launched by FNIRSI, specially designed for professionals in maintenance, development, education, and home use. Compact yet powerful, both models integrate three essential functions: oscilloscope, multimeter, and signal generator—making them ideal for versatile testing needs.

Both devices adopt a FPGA+MCU/ARM+ADC architecture with built-in high-voltage protection (±400V peak).

  • 2C23T features a 50MS/s sampling rate and 10MHz bandwidth.

  • 2C53T upgrades to a 250MS/s sampling rate and 50MHz bandwidth, providing higher precision and faster signal capture.

The multimeter in 2C23T offers 4-digit 10000-count true RMS, while 2C53T enhances it with 4.5-digit 19999-count true RMS, supporting AC/DC voltage and current, resistance, capacitance, diode, and continuity measurements.

The DDS signal generator in 2C23T outputs 7 signal types up to 2MHz, while 2C53T supports 13 signal types up to 50kHz. Both offer 1Hz step adjustment, with customizable frequency, amplitude, and duty cycle.

Each model is equipped with a 2.8-inch 320×240 HD display and a 3000mAh rechargeable battery, delivering up to 6 hours of standby time. With waveform screenshot saving and viewing support, these devices combine portability, power, and practicality in one tool.
