FNIRSI DPOX180H 2-in-1 handheld digital phosphor oscilloscope 180MHz 500MSPS

The FNIRSI DPOX180H is a handheld digital phosphor oscilloscope that combines a two-channel 180 MHz scope, up to 500 MSPS real-time sampling and a 20 MHz DDS function generator in one compact unit. It is designed for service, workshop and laboratory work where a portable instrument is needed.

Digital phosphor technology shows signal occurrence through brightness levels and colour temperature, making jitter, noise, instability and rare events easier to spot than on a conventional scope. With 50,000 waveforms per second, the acquisition dead time is kept low, which is useful when analysing switch-mode power supplies and digital buses.

A switchable 20 MHz hardware bandwidth limit reduces noise and high-order harmonics, while the trigger system with Auto, Normal and Single modes and adaptive trigger stabilisation helps keep the display steady. FFT, X-Y mode, time zoom and a 2.8-inch IPS colour screen round out the feature set.
