Product details
FNIRSI 2C53T puts three bench tools in one handheld body: a dual-channel 50 MHz oscilloscope, a 19999-count true RMS multimeter and a DDS signal generator. Built on an FPGA + ADC + ARM design, the scope samples at 250 MS/s, so you can see real switching waveforms, ripple and PWM signals while working on the board — not just a single voltage reading. The 2.8-inch colour screen, 3000 mAh rechargeable battery with Type-C charging and fold-out stand make it practical for field repair of inverters, UPS and SMPS boards, automotive work and student lab practicals, where a bench scope would be too heavy or too expensive. Key Features 🧰 3-in-1 design — oscilloscope, multimeter and signal generator in one device. ⚡ 50 MHz, 2 channels, 250 MS/s — compare two signals for timing, phase and duty-cycle checks. 📊 X-Y mode and FFT — view signal frequency content and Lissajous patterns. 📏 19999-count true RMS multimeter — AC/DC voltage, current, resistance, capacitance, temperature, diode and continuity. 🎛️ Built-in signal generator — 13 waveform types, 0–50 kHz, 0–3 V amplitude, 0–100% duty cycle. 🔋 3000 mAh battery, Type-C charging — up to 6 hours of use per charge. ✅ Waveform save and export — keep captures for later comparison and reports.
