FNIRSI® 2C53T 50MHz 250MS/s Handheld 3in1 Oscilloscope Multimeter Signal Generator

Product Description

The FNIRSI® 2C53T is a multifunctional 3-in-1 handheld electronic testing instrument that combines a dual-channel digital oscilloscope, a True RMS digital multimeter, and a DDS function signal generator in one compact portable device. Designed for electronic maintenance technicians, engineers, electronics students, and hobbyists, it provides essential waveform analysis, electrical measurement, and signal generation capabilities.

The integrated dual-channel oscilloscope features a 50MHz analog bandwidth and a maximum real-time sampling rate of 250MSa/s, allowing users to observe and analyze two electronic signals simultaneously. With a storage depth of 1Kpts, adjustable vertical sensitivity from 10mV/div to 10V/div, and multiple trigger modes, it supports waveform acquisition and analysis for various electronic testing applications.

The oscilloscope also features advanced waveform analysis functions, including mathematical operations, cursor measurements, persistence mode, and XY display mode. Its FFT function provides an approximate representation of signal frequency components, while the infinite afterglow function helps visualize waveform variations over time. Waveform screenshots can be saved directly on the device and exported to a computer through the USB Type-C interface.

The integrated 4.5-digit, 19,999-count True RMS digital multimeter supports AC/DC voltage and current measurements, resistance, capacitance, and temperature measurements, as well as diode and continuity testing. This provides a comprehensive range of electrical measurement functions in the same instrument.

Additionally, the built-in DDS signal generator supports 13 waveform types with an adjustable output frequency from 0 to 50kHz, output amplitude from 0 to 3V, and duty cycle adjustment from 0 to 100%. Its 1Hz frequency adjustment step allows convenient signal configuration for electronic circuit testing.

Featuring a 2.8-inch HD color LCD display with a 320 × 240 resolution, FPGA + MCU + ADC hardware architecture, and an integrated high-voltage protection module, the FNIRSI 2C53T provides a practical combination of measurement and signal analysis capabilities.

Powered by a built-in 3000mAh rechargeable lithium battery, the device offers a standby time of up to 6 hours under the manufacturer's stated laboratory theoretical maximum conditions. Its compact dimensions of 167 × 89 × 35mm and weight of approximately 300g make it suitable for portable electronic testing, maintenance, and troubleshooting.
