The FNIRSI 2C53T combines the functions of a 2×50 MHz/250 MSa/s oscilloscope with an 8-bit ADC and 16 kpct memory buffer per channel (pre/post-trigger), a multimeter up to 19999 and a 50 kHz signal generator. Input impedance is 1 MΩ ∥ 15 pF with AC/DC/GND switching. The rugged ABS housing with silicone overlays, 2.8-inch 320×240 px screen and 3000 mAh battery (up to 4 h of operation) guarantee mobility and continuous measurements even in harsh environments. The device is CAT II 300 V certified, with dual ceramic fuses and an anti-overvoltage circuit. With the ability to save waveforms and update firmware, you are always in control of your results and have access to the latest features.
The 2.8″ display with a resolution of 320×240 px presents waveforms in full color with an "infinite afterglow" function (fixes the signal trace on the screen, even after it fades), keeping the waveform trace on the screen. Y-T, Rolling and X-Y modes (so-called Lissajous figures for analyzing phase differences between signals) make it easy to observe phase relationships, and high brightness guarantees readability in all conditions. A built-in multimeter with up to 19999 resolution allows you to measure DC/AC, low and high currents, resistance, capacitance, diodes, temperature and continuity (buzzer). Smart protections protect the user and equipment from overload.
The professional ARM + FPGA + high-performance ADC combination, used in desktop oscilloscopes, provides fast triggering and faithful representation of signals. The triggering system offers Edge (rising/falling), Pulse Width, Video and Slope modes with pre-trigger up to 50% and post-trigger up to 50%, so even the shortest anomalies are recorded without loss of detail.
The built-in function generator offers voltages up to ±400 V and frequencies up to 50 kHz and 13 waveforms (sine, square, triangle, sawtooth, ramp, pulse, noise, etc.) with adjustable offset (signal offset relative to zero) and amplitude in 10 mV/div steps, allowing testing of filters, amplifiers and analog circuits without additional hardware.
The AUTO function adjusts the range and trigger with a single button, allowing instant waveform viewing without time-consuming setup. Support for additional Single and Normal modes streamlines work for quick field measurements. One click is all it takes to save a screenshot of the waveform to the oscilloscope's memory or directly to a computer via USB. This makes it easy to archive results and further analyze them in any environment.
Two completely independent CH1 and CH2 inputs with 50 MHz bandwidth eliminate mutual interference, improving measurement precision. The 250 MSa/s sampling rate reproduces PWM pulses and power supply ripples with maximum fidelity.
The ABS (Acrylonitrile Butadiene Styrene - a high-strength plastic) silicone-coated housing provides drop and shock resistance, and the gold-plated PCB (Printed Circuit Board) tracks are corrosion-resistant. The 3,000 mAh battery guarantees up to 3 hours of operation. The fold-out stand allows the device to be positioned at any angle, while ergonomic buttons and a USB-C port provide convenience in handling and charging.
