Description
Description	FNIRSI DPOS350P 4-in-1 Digital Oscilloscope The FNIRSI DPOS350P is a versatile digital oscilloscope designed for convenient and intuitive operation. 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. Full control over the signal 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 "engineer's second pair of eyes" – indispensable for diagnostics and testing. Maximum functionality 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 – 350 MHz range), and frequency response analyzer (100 kHz – 50 MHz). Such a wide range of functions means that one device replaces several specialized tools, saving space and time. High measurement performance 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's more, the FNIRSI DPOS350P allows Bodé chart analysis in the 100 Hz – 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. Advanced spectrum and EMI analysis 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. Signal visibility like never before 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. Tablet design that makes work easier 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—without unnecessary menus and complicated navigation. This is a device that naturally adapts to the user's work rhythm. The oscilloscope supports multiple languages, including English, Chinese, Russian, and Portuguese, making it ideal for international environments.
