FNIRSI DPOX180H 2-in-1 Handheld Digital Phosphor OscilloscopeThe 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 precisionThe 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 waveformThe 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 timeThe 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 triggerThe 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 analysisThe 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 modeThe 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 functionThe 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 exportThe 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 useThe 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.

FNIRSI 1013D 7" portable tablet oscilloscopeThe FNIRSI 1013D portable oscilloscope with a 7" touch screen, 2 measurement channels, 100 MHz bandwidth and 1 GSa/s sampling rate allows precise signal analysis in service, workshop and electronic device design. The device is equipped with an easy-to-read 800x480 TFT screen, automatic one-button signal adjustment, and waveform recording function, allowing convenient and fast measurements anywhere. Support for analog and digital signal analysis makes it suitable for equipment service and DIY applications. The built-in 6,000 mAh lithium battery allows the device to operate for about 4 hours.Clear touchscreenThe FNIRSI 1013D features a 7-inch TFT LCD screen with 800x480 resolution, providing high brightness, contrast and accurate waveform reproduction. Touch operation of the screen allows quick zooming, panning and changing of measurement parameters, speeding up work without the need for physical buttons. The screen is made with capacitive technology, known from modern smartphones, which ensures smooth operation and no delays when changing settings. The cursor measurement function allows accurate reading of signal amplitude, period and frequency without the need to convert units from the screen's grid, which is especially useful with distorted signals or rectangular waveforms with noise.Two measurement channelsThe device is equipped with two measurement channels with an input impedance of 1 MΩ, which allow the analysis of two signals simultaneously, making it easier to compare the input and output of amplifier circuits, converters or PWM signal analysis. This makes the range of applications much wider than with single-channel models. You can also perform Lissajous pattern analysis in XY mode, which allows you to determine the frequency, amplitude and phase shift between two groups of signals.Automatic signal adjustmentThe one-button automatic adjustment function allows you to instantly adjust signal measurement parameters without manual calibration. As a result, the FNIRSI 1013D can adjust the settings for a 1 Vpp signal within 1 second, saving time and increasing work efficiency. The built-in fuzzy logic algorithm ensures high accuracy and automatically places the signal in the center of the screen, making analysis much easier.Protection against damageThe oscilloscope uses built-in surge protection modules up to 400 V to prevent accidental damage to the device when measuring high-voltage signals, even if the probe is not set to 10X mode. This allows you to safely test power and high-voltage circuits.Data storage and exportThe FNIRSI 1013D offers an internal memory of 1 GB, which allows you to store up to 1,000 images and 1,000 waveform sets. This allows you to quickly save one-touch measurement results and export them via USB to a computer for further analysis. The waveform manager function allows you to view thumbnails of stored waveforms, zoom in, delete and analyze them with a cursor directly on the device - similar to a smartphone gallery, adding to the convenience of data management.Advanced triggering functionsThe oscilloscope offers a full set of trigger modes - Auto, Single and Normal. This arrangement allows you to test sudden pulsed ignition signals, IR remote control signals or sine wave signals depending on the selected mode, making the device a versatile diagnostic tool. You can also set the trigger edge (rising/falling) and trigger channel, allowing you to precisely capture the signal fragments of interest.Included: FNIRSI 1013D portable touchscreen oscilloscope Probe (100 MHz) x2 USB charger User manual Manufacturer FNIRSI Model 1013D Number of channels 2 LCD screen size 7 inches LCD resolution 800 x 480 Display technology TFT Bandwidth 100 MHz Sampling frequency 1 GSa/s Highest test voltage 1X: 40V10X: 400V Cursor XY positionTrigger Y Roll mode Supported Automatic one-button setting Supported Waveform storage 1000 images + 1000 waveforms Waveform manager Supported Volt
