🔬 FNIRSI DPOX180H 180MHz

Portable Dual-Channel Digital Phosphor Oscilloscope with DDS Function Signal Generator

📖 Product Description

The FNIRSI DPOX180H is a professional portable dual-channel digital phosphor oscilloscope featuring a built-in DDS function signal generator, combining advanced waveform analysis and signal generation in a single compact instrument.

Designed for electronics engineers, maintenance technicians, educational laboratories, automation specialists, radio amateurs, and embedded system developers, the DPOX180H delivers excellent performance for both laboratory and field applications.

With a 180 MHz analog bandwidth, 500 MSa/s real-time sampling rate, and waveform refresh rate of up to 50,000 waveforms per second, the oscilloscope captures fast transient events and intermittent signal anomalies with exceptional accuracy. Digital Phosphor (DPO) technology significantly improves waveform visibility, making signal analysis easier and more reliable.

The integrated 20 MHz DDS function generator eliminates the need for a separate laboratory signal source for many testing applications.

Its bright 2.8-inch IPS color display, rechargeable lithium battery, USB connectivity, and compact handheld design make it an excellent choice for both desktop and portable use.
