FNIRSI-2C53T is a versatile and highly practical three-in-one dual-channel digital oscilloscope launched by FNIRSI, designed for professionals in the maintenance and research industries. This device combines the functionalities of an oscilloscope, a multimeter, and a signal generator. The oscilloscope uses FPGA+ARM+ADC hardware architecture, featuring a 250MS/s sampling rate, a 50MHz analog bandwidth, and an integrated high-voltage protection module that supports peak voltage measurements up to ±400V. It also supports waveform screenshot saving and viewing for secondary analysis.

The multimeter function offers 4.5 digits with 19999 counts true RMS, supporting AC/DC voltage and current measurements, as well as capacitance, resistance, diode, and continuity measurements, making it an ideal multifunctional instrument for professionals, factories, schools, enthusiasts, or home use.

The built-in DDS function signal generator can output 13 types of function signals, with a maximum output frequency of 50KHz and a step size of 1Hz. The output frequency, amplitude, and duty cycle are adjustable. It features a 2.8-inch 320*240 resolution high-definition LCD screen and a built-in 3000mAh rechargeable lithium battery with a standby time of up to 6 hours. Its compact size provides users with more powerful practical functions and excellent portability.

Key Features:

1Anti-burning: Dual ceramic fuse protective circuit. Intelligent anti-burn with overload protection, and built-in double fuse making it safer

Excellent performance: The hardware architecture adopts the same ARM+FPGA+high-speed ADC scheme as desktop computers, with high cost. it is not an ordinary CPU direct acquisition scheme, and has a powerful triggering system with super strong waveform capture ability, without losing waveform details.

2Waveform detail analysis: It supports advanced functions such as XY mode, cursor measurement, persistence measurement, mathematical operations, etc., making it easy to capture abnormal signals. Supports waveform saving and exporting for convenient secondary analysis.

3Waveform saving and viewing: Save a screenshot of the waveform with one click. The saved image can be viewed in an oscilloscope or exported to a computer facilitating secondary analysis.
