It features a large 7-inch touch screen for clear signal viewing and quick access to key functions. It combines the features of an oscilloscope, signal generator, spectrum analyzer, and frequency response analyzer, making it suitable for a wide range of measurement applications. High bandwidth, fast sampling, and large memory enable precise signal analysis, while advanced visualization modes improve measurement readability.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Benchtop digital oscilloscope with blue waveforms displayed.\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/19508\/25995\/Oscyloskop-cyfrowy-4w1-FNIRSI-lifestyle-4.jpg\"\/>\n<\/p><h3>Full control over the signal<\/h3>\n<p>The large 7-inch touch screen provides a full view of the analyzed signal and precise parameter control. The clear interface allows you to quickly understand the behavior of the system, and the high image quality makes the DPOS350P an &quot;engineer&#x27;s second pair of eyes&quot; \u2013 indispensable for diagnostics and testing.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Finger touching the oscilloscope screen with waveforms displayed.\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/19508\/25995\/Oscyloskop-cyfrowy-4w1-FNIRSI-lifestyle-8.jpg\"\/>\n<\/p><h3>Maximum functionality<\/h3>\n<p>The FNIRSI DPOS350P is an advanced 4-in-1 oscilloscope that offers the functions of four different devices. It is an oscilloscope (2 channels, 350 MHz bandwidth, 1 GSa\/s sampling, 8-bit resolution, 50,000 waveforms per second), signal generator (up to 50 MHz), spectrum analyzer (200 kHz \u2013 350 MHz range), and frequency response analyzer (100 kHz \u2013 50 MHz). Such a wide range of functions means that one device replaces several specialized tools, saving space and time.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Digital oscilloscope with graphical examples of waveforms in the background.\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/19508\/25995\/Oscyloskop-cyfrowy-4w1-FNIRSI-lifestyle-9.jpg\"\/>\n<\/p><h3>High measurement performance<\/h3>\n<p>The DPOS350P model offers a bandwidth of 350 MHz, a sampling rate of 1 GSa\/s, and a memory depth of 60 kpts, which translates into accurate signal reproduction and stable measurements even with complex waveforms. What&#x27;s more, the FNIRSI DPOS350P allows Bod\u00e9 chart analysis in the 100 Hz \u2013 50 MHz range, with adjustable frequency, excitation amplitude, and offset. It is the ideal tool for testing amplifiers, filters, and power loops, allowing you to quickly and accurately assess the frequency response of a circuit.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Digital oscilloscope in midair with dynamic graphical effects.\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/19508\/25995\/Oscyloskop-cyfrowy-4w1-FNIRSI-lifestyle-2.jpg\"\/>\n<\/p><h3>Advanced spectrum and EMI analysis<\/h3>\n<p>The device covers a frequency range from 200 kHz to 350 MHz and allows for precise manual adjustment of key parameters (start\/stop frequencies, bandwidth, reference level, attenuation, and FFT length). Cursor measurement functions and advanced visualization modes are at your disposal, including an impressive and extremely clear 3D Waterfall view. This makes the oscilloscope ideal for EMI testing, RF signal analysis, and harmonic detection.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Close-up of the oscilloscope screen with a view of the frequency spectrum.\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/19508\/25995\/Oscyloskop-cyfrowy-4w1-FNIRSI-lifestyle-5.jpg\"\/>\n<\/p><h3>Signal visibility like never before<\/h3>\n<p>Digital fluorescence technology provides exceptional signal clarity and precise color reproduction. In addition, advanced noise filtering improves waveform detection and presentation, enabling more accurate signal analysis. Support for 8-16-bit technology takes image clarity to the next level.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Two test leads connected to channels CH1 and CH2 of a digital oscilloscope\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/19508\/25995\/Oscyloskop-cyfrowy-4w1-FNIRSI-lifestyle-7.jpg\"\/>\n<\/p><h3>Tablet design that makes work easier<\/h3>\n<p>The slim housing in an elegant black finish with blue accents combines modern design with ergonomics. The tablet form factor allows for comfortable one-handed operation, and the touch interface makes all functions immediately accessible\u2014without unnecessary menus and complicated navigation. This is a device that naturally adapts to the user&#x27;s work rhythm. The oscilloscope supports multiple languages, including English, Chinese, Russian, and Portuguese, making it ideal for international environments.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Digital
