FNIRSI 2C53T Upgraded 3-IN-1 Oscilloscope Multimeter Signal Generator

The oscilloscope uses FPGA + ARM + ADC hardware architecture, featuring a 250MSa/s real-time sampling rate and 50MHz analog bandwidth. An integrated high-voltage protection module supports peak voltage measurements up to ±400V. It also supports waveform screenshot saving and viewing for secondary analysis.

The multimeter provides 4.5-digit, 19999-count True RMS measurement, supporting AC/DC voltage and current measurements as well as capacitance, resistance, diode, continuity, frequency, and temperature measurements. It is an excellent multifunctional instrument for professionals, factories, schools, electronics enthusiasts, and home use.

The built-in DDS function signal generator can output 13 types of waveforms, with a maximum output frequency of 50kHz and a frequency adjustment step of 1Hz. Output frequency, amplitude, and duty cycle are adjustable.

The unit features a 2.8-inch 320 × 240 TFT color LCD display and a built-in 3.7V 3000mAh rechargeable lithium battery, providing up to approximately 6 hours of theoretical standby time.
