The FNIRSI DPOX180H is a dual-channel digital phosphor oscilloscope featuring a comprehensive signal generator function. It boasts a real-time sampling rate of 500MSPS, a 180MHz analog bandwidth, and a waveform refresh rate of 50,000wfm/s, enhancing its ability to display low probability abnormal signals. With a 2.8-inch IPS full visual LCD display screen and digital phosphor technology, the color scheme is grayscale and color temperature, ensuring an excellent waveform display effect. Its time base system includes Zoom time bases, facilitating the analysis of digital protocol signals.

Equipped with original adjustable automatic bandwidth limitation and adaptive adjustable trigger suppression, it's well-suited for analyzing and measuring signals with high noise levels. The hardware's bandwidth limit of 20M can effectively filter out noise above 20MHz. It features a DDS signal generator offering 14 function signal waveforms and a freely customizable truncated waveform. The sine wave frequency can reach up to 20MHz, while other waveforms can reach up to 10MHz.

A unique chopping output function allows for the storage of up to 500 customized signals. Manual cursor measurement, one-click waveform and screenshot saving, and a data browser for browsing and viewing currently saved waveform data and images are included. Additionally, waveform data supports operations such as scaling and moving. With high voltage anti-burn protection, all gears can withstand up to 400V high voltage.

Kian Nitzsche

As described. Seems to be robust, has a nice touch . If it came with one box to carry all the pack it would be better. For the price it costs I think this is the minus for this item.

Itzel Kovacek

Priishov Shvidko, packed good, for this very normal device

Monserrate Stokes

It arrived fast to México, the device is smaller than expected but it looks very nice. I have not tested yet but seems to comply with manufacturer specifications. Happy with the purchase up to now.

Aurelio Hackett

Quick delivery, the seller even added a second adapter (EU), because in the set it was different. I just asked the adapter to be EU type.
I am very satisfied.

Hettie Wisoky

product arrived quickly and worked as described.



Please read our FAQs page to find out more.

Why can't the device be turned on after receiving it?

The power-on operation involves pressing the power button. If the device still cannot be turned on, it might indicate that the battery is depleted. Connect the provided USB cable to charge it; the power button will display red during charging. You can start the device once it's charged.

Why is there no waveform displayed during the test, only a straight baseline on the screen?

Please check whether the pause button is pressed. If not, press the [AUTO] button. If the issue persists, it may be due to the signal source having no signal output, or the probe line being short-circuited or open-circuited. Please use a multimeter to check the probe and verify whether the signal source is functioning normally.

Why is the voltage value zero?

Please adjust the vertical sensitivity and time base (sampling rate), or press [AUTO]. Ensure that a clear and complete cycle waveform is displayed on the screen, and that the top and bottom of the waveform are fully visible without clipping. At this point, the voltage value should be correct.

Why is there a significant offset between the baseline (0V) and the left arrow (0V indication) on the screen when there is no signal input?

First, pull out the probe, then perform system calibration once. After calibration is completed, the baseline will coincide with the arrow.

Why can't the oscilloscope capture sudden pulse waveforms or digital logic signals?

Adjust the trigger mode to Single trigger mode, then adjust the trigger voltage, time base, and vertical sensitivity. Finally, release the pause and wait for the arrival of the burst signal; it will automatically pause after being captured.
