FNIRSI Handheld Digital Oscilloscope Multimeter Signal Generator 2CH 50MHz 2C53T

About this deal

The FNIRSI 2C53T is a three-in-one handheld instrument that combines a dual-channel digital oscilloscope, a multimeter, and a DDS signal generator in a single compact unit. The oscilloscope uses an FPGA + ARM + ADC hardware architecture, delivering a 250MS/s sampling rate and 50MHz analogue bandwidth, with a high-voltage protection module supporting peak measurements up to +/-400V. As an upgraded version of the 2C23T, it adds math operations, cursor measurement, persistence mode, and XY mode. The multimeter offers 4.5-digit true RMS readings with 19,999 counts, covering AC/DC voltage and current, capacitance, resistance, diode testing, and continuity measurement. The built-in DDS signal generator outputs 13 types of waveform with a maximum frequency of 50kHz and 1Hz step resolution, with adjustable frequency, amplitude, and duty cycle. The device features a 2.8-inch 320x240 colour LCD and a built-in 3,000mAh rechargeable lithium battery with up to six hours of standby time. It charges via USB-C and comes supplied with two oscilloscope probes, multimeter leads, and a carrying case.
