Description
The updated FNIRSI 2C53T, an enhanced version of its 10 MHz predecessor, is a compact and versatile 3-in-1 device. It combines a dual-channel 50 MHz oscilloscope, a 4.5-digit True RMS multimeter, and a signal generator with 13 waveform types, making it an essential tool for maintenance and research professionals.
- Oscilloscope: Features 50 MHz bandwidth, 250 MS/s sampling rate, ±400 V protection, FPGA + ARM + ADC architecture, and waveform saving for analysis.
- Multimeter: 4.5-digit True RMS with 19999 counts, supports AC/DC voltage, current, capacitance, resistance, diode, and continuity measurements.
- Signal Generator: Outputs 13 signal types up to 50 KHz, with adjustable frequency, amplitude, and duty cycle.
With a 2.8-inch LCD, 3000 mAh battery (6-hour runtime), and a portable design, it delivers powerful functionality in a user-friendly package.
