FNIRSI DPOS350P – 4-in-1 Digital Oscilloscope with 350 MHz Bandwidth, 2 Channels, 50 MHz Signal Generator, Spectrum and Frequency Analyzer
Product Description (Rewritten)
The FNIRSI DPOS350P is a powerful 4-in-1 test instrument that combines a 350 MHz dual-channel digital phosphor oscilloscope, a 50 MHz signal generator, a 200 kHz–350 MHz spectrum analyzer, and a 50 MHz frequency response analyzer. It features a 1 GSa/s real-time sampling rate, 350 MHz bandwidth, and an ultra-fast waveform refresh rate, making it ideal for capturing even weak or complex signals.
Equipped with a 7-inch 1024×600 IPS touchscreen, the device offers sharp waveform displays and intuitive operation, perfect for labs, production lines, and field maintenance.
The built-in signal generator supports 14 standard and custom waveforms, while the spectrum analyzer covers frequencies from 200 kHz to 350 MHz – ideal for EMI and RF analysis.
Highlights:
-
High-voltage protection up to 400 V
-
Fast charging (QC 18 W, full in 2 hours)
-
Stores 500 waveforms & 90 screenshots
-
USB export for convenient analysis and reporting
