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.\u003c\/p\u003e\u003cp\u003eThe 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
