FNIRSI® DPOX180H 2 Channel 180MHZ 2-IN-1 Digial Phosphor Oscilloscope & Function Generator

The FNIRSI DPOX180H is a cost-effective, handheld 2-channel digital phosphor oscilloscope that integrates a DDS signal generator for field and bench use. It delivers a 500MSa/s real-time sampling rate with 180MHz analog bandwidth and a maximum capture rate of 50,000 waveforms per second to reveal intermittent anomalies. The unit features a 2.8-inch high-contrast IPS LCD, a ZOOM time base for detailed protocol and transient analysis, and vertical sensitivity down to 5mV for precise small-signal measurement.

Key functions include digital phosphor display, noise filtering, and a high-precision digital trigger with Auto/Normal/Single modes. The built-in DDS function generator supports signals up to 20MHz. Practical usability features include one-button auto adjustment, waveform image storage and USB export, storage capacity for waveform sets, and fast charging via 5V/2A input. The instrument also incorporates high-voltage input protection rated to ±400V.

Specifications highlight a 120Kpts storage depth, 500MSPS maximum sampling rate, 2.5ns rise time, input impedance of 1MΩ // 18pF, time base range of 5ns–50s, vertical sensitivity 5mV–10V (1X), measurement range 40mV–80V (1X), IPX6 water resistance, FFT and X-Y modes, adjustable bandwidth limitation including 20MHz hardware limit, and cursor measurement for frequency, period, and amplitude. This combination of features provides a portable, multifunction oscilloscope and signal generator suitable for diagnostics, education, and electronic development tasks.
