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 180 MHz dual-channel oscilloscope, a 20 MHz DDS function generator, and advanced signal analysis functions. It is designed as a compact, mobile tool for service, workshop, and laboratory work, offering high functionality in a single device.


180 MHz bandwidth and 500 MSPS – measurement precision
The oscilloscope offers 180 MHz (-3 dB) analog bandwidth and real-time sampling up to 500 MSPS (250 MSPS in dual-channel operation). This allows for accurate reproduction 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 waveform
The Digital Phosphor technology uses brightness scale and color temperature to visualize signal frequency. This makes it easy to spot jitter, noise, instabilities, and rare events that may remain invisible in classic 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 you to effectively capture short-term disturbances and signal anomalies, which is particularly important when analyzing switching power supplies and digital buses.


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


FFT and X-Y mode – frequency and relationship analysis
The FFT function provides a quick, qualitative preview of the frequency spectrum of the signal under test. In addition, the X-Y mode with digital phosphor allows you to analyze the amplitude and phase relationships between two channels, e.g., in the form of Lissajous figures.


Time zoom and scroll mode
The oscilloscope offers a ZOOM time base in the range of 2×–1000×, allowing for accurate analysis of selected waveform segments. The scroll mode allows for continuous observation of slow-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. The unique chopping output function allows you to cut out a fragment of the measured waveform and use it as the generator output signal, with the ability to save up to 500 custom signals.


Data storage, viewing, and export
The internal 120 Mbit memory can store 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" (320×240) color IPS screen ensures good readability in all conditions. The device is equipped with one-button automatic configuration, cursor measurements, input protection up to 400 V, a 3000 mAh Li-ion battery (up to approx. 4 hours of operation), and fast 5 V / 2 A charging. The FNIRSI DPOX180H is a versatile and safe tool for electronics engineers, service technicians, students, and demanding hobbyists.
