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.
