The DPOX180H is a cost-effective, handheld dual-channel digital phosphor oscilloscope from FNIRSI, combining an oscilloscope and signal generator. It features a 500MSPS real-time sampling rate, 180MHz bandwidth, and a 2.8-inch high-contrast IPS LCD. With a refresh rate of up to 50,000 waveforms per second, it captures even rare signal anomalies. The ZOOM time base aids digital protocol analysis, and with 5mV sensitivity, it can measure small signals accurately. Key features include noise filtering, a high-precision digital trigger with three modes, and a DDS signal generator supporting up to 20MHz. Additional functions include one-button auto adjustment, waveform storage for up to 250 sets, high-voltage protection up to 400V, USB export, and fast charging (5V/2A).
