FNIRSI DPOX180H is a compact handheld instrument that combines in one body a 180 MHz dual-channel Digital Phosphor Oscilloscope (DPO) and a 20 MHz DDS function generator. With up to 500 MSPS sampling, 50,000 wfms/s refresh rate, and features such as FFT, X‑Y mode, and time zoom, it is ideal for service work, workshops, and laboratory diagnostics of modern electronics.
Looking for a mobile oscilloscope that can handle quick troubleshooting as well as advanced signal analysis? The FNIRSI DPOX180H offers a 180 MHz bandwidth (-3 dB) and real-time sampling up to 500 MSPS (250 MSPS with 2 channels), so it faithfully displays fast edges, pulses, and high-frequency waveforms. Thanks to Digital Phosphor technology, you can also see effects that are easy to miss on conventional oscilloscopes—jitter, noise, instability, or rare events.
The high refresh rate of 50,000 waveforms/s minimizes acquisition “dead time” and helps capture short-term faults, for example in switching power supplies or digital buses. For a cleaner display, there is a switchable 20 MHz hardware bandwidth limit and stable triggering (Auto/Normal/Single, rising/falling edge).
Also included is a 20 MHz DDS generator with 14 waveform types and a 1 Hz setting step. The practical chopping function lets you cut out a portion of the measured waveform and use it as an output signal (store up to 500 custom signals). Measured data can be easily saved to internal memory and exported to a PC via USB; firmware updates are also performed via USB.
- 2-channel DPO oscilloscope + DDS generator in one device
- FFT for a quick spectrum overview and X‑Y mode for analyzing relationships between channels (e.g., Lissajous figures)
- Timebase zoom 2×–1000× and scroll mode for long records and slow processes
- 2.8" IPS LCD (320 × 240) for good readability in the field
- Input protection up to 400 V, 3000 mAh Li-ion battery, runtime up to about 4 hours
