Description
The DPOS350P is a high-performance all-in-one tablet oscilloscope, designed to offer precision, reliability and versatility in a single compact device.
Thanks to its integrated 4-in-1 structure, it combines the functions of a digital oscilloscope, signal generator, spectrum analyzer and frequency response analyzer, making it the ideal instrument for technicians, engineers, maintenance staff and advanced electronics enthusiasts.
Professional performance in a portable format
With a 350MHz bandwidth, a real sampling rate of 1GSPS and a memory depth of 60Kpts, the DPOS350P guarantees accurate acquisition even of the most complex and transient signals. A waveform update rate of 50,000 wfm/s allows rapid detection of rare events or anomalies.
Modern, intuitive interface
The 7-inch IPS display (1024×600) offers a clear, detailed view of waveforms, with grayscale or colour display modes suited to any operating environment. The capacitive touchscreen makes interaction smooth and natural, making real-time adjustments and measurements easier.
Signal generator and advanced RF analysis
The built-in 50MHz signal generator supports 14 standard waveforms (including sine, square, triangle, etc.) and also allows the creation of custom waveforms, useful for specific tests.
The built-in spectrum analyzer, with FFT conversion and a range from 200KHz to 350MHz, is perfect for EMI/RF analysis, high-frequency testing and interference detection. The 3D waterfall function offers clear, professional time-domain spectrum analysis.
Frequency response analysis
The FRA (Frequency Response Analyzer) module enables Bode plot testing and evaluation of filters, amplifiers and other linear circuits over a range from 100Hz to 50MHz, with full control over the frequency, amplitude and offset of the excitation signal.
Safety and battery life
The DPOS350P features robust overvoltage protection up to 400V, ensuring safety in critical applications. The 8000mAh lithium battery and QC18W fast charging provide up to 3 hours of full battery life and a complete recharge in just 2 hours. Perfect for field use or where direct power is unavailable.
Storage and connectivity
It supports saving up to 500 waveforms and 90 images, with USB export for easy analysis, documentation and data sharing. The device can also be updated via firmware to keep up with new features.
