FNIRSI DPOX180H 2-in-1 Handheld Digital Phosphor Oscilloscope

FNIRSI DPOX180H 2-in-1 Handheld Digital Phosphor Oscilloscope

The FNIRSI DPOX180H is a handheld Digital Phosphor Oscilloscope (DPO) that combines a dual-channel 180 MHz oscilloscope, a 20 MHz DDS function generator, and advanced signal analysis features. It is designed as a compact, portable tool for service, workshop, and laboratory use, offering high functionality in a single device.

180 MHz bandwidth and 500 MSPS – measurement precision

The oscilloscope offers an analog bandwidth of 180 MHz (-3 dB) and real-time sampling up to 500 MSPS (250 MSPS in dual-channel operation). This enables faithful representation of fast edges, pulses, and high-frequency signals, which is crucial in the diagnosis of modern electronic systems.

Digital Phosphor Technology – more information in the course

Digital Phosphor technology uses a brightness scale and color temperature to visualize the frequency of a signal. This makes it easy to spot jitter, noise, instabilities, and rare events that may remain invisible in traditional oscilloscopes.

50,000 wfms/s – no dead time

The high refresh rate of 50,000 waveforms per second significantly reduces acquisition dead time. This allows for the effective capture of short-term interference and signal anomalies, which is particularly important when analyzing switched-mode power supplies and digital buses.

Hardware 20 MHz bandwidth limit and stable trigger

The built-in switchable hardware 20MHz bandwidth filter effectively reduces noise and high-order harmonics. Combined with the extensive trigger system (Auto / Normal / Single, rising and falling edge) and adaptive trigger stabilization, it ensures a clean and stable signal image.

FFT and XY mode – frequency and relationship analysis

The FFT function allows for a quick, qualitative preview of the frequency spectrum of the signal being tested. Additionally, the XY mode with digital phosphor allows for the analysis of amplitude and phase relationships between two channels, for example, in the form of Lissajous figures.

Time Zoom and Scroll Mode

The oscilloscope offers time-base ZOOM in the 2×–1000× range, enabling detailed analysis of selected waveform fragments. Roll/scroll mode allows for continuous observation of slowly changing signals in real time.

20 MHz DDS generator and chopping function

The built-in 20 MHz DDS function generator supports 14 waveform types, with frequency adjustment in 1 Hz steps. A unique chopping output feature allows you to cut a portion of the measured waveform and use it as the generator's output, with the ability to store up to 500 custom signals.

Saving, viewing, and exporting data

The internal 120 Mbit memory stores up to 250 waveforms and 90 screenshots (BMP). Data can be viewed directly on the device or exported to a computer via USB, and the firmware can be easily updated.

Mobility, safety and ease of use

The 2.8" (320x240) IPS color screen ensures good readability in all conditions. The device is equipped with one-button automatic configuration, cursor measurements, 400V input protection, a 3000mAh Li-ion battery (up to approx. 4 hours of operation), and 5V/2A fast charging. The FNIRSI DPOX180H is a versatile and safe tool for electronics engineers, service technicians, students, and demanding hobbyists.
