The FNIRSI DPOS350P combines four instruments in one portable tablet: dual-channel oscilloscope, signal generator, spectrum analyzer and frequency response analyzer.
One device replaces a bench full of separate equipment.
DPOS350P Four Instruments in One
Digital Phosphor Oscilloscope
350MHz analog bandwidth in single-channel mode.
Dual-channel operation for comparing signals.
1GSa/s real-time sampling rate captures fast-changing waveforms.
Digital phosphor display shows signal intensity and frequency of occurrence.
Waveform refresh rate of 50,000 waveforms per second.
Catch intermittent glitches and rare events that slower scopes miss.
Signal Generator
Built-in 50MHz function generator.
14 standard waveforms including sine, square, triangle and more.
Custom waveform functionality for specialist applications.
Generate test signals without carrying a separate instrument.
Spectrum Analyzer
Frequency range from 200kHz to 350MHz.
View signals in the frequency domain.
Identify frequency components, harmonics and interference.
Useful for EMI investigation, RF work and high-frequency signal analysis.
Frequency Response Analyzer
Analyse how circuits and systems respond across a range of frequencies.
Measure gain and phase response.
Useful for filter design, amplifier testing and control system analysis.
Frequency range up to 50MHz.
7-Inch Touchscreen Display
High-resolution IPS screen at 1024 × 600 pixels.
Clear, detailed waveform display.
Touch operation for intuitive navigation.
Pinch, zoom and drag waveforms directly on screen.
Grayscale and colour temperature display modes.
Adjust to suit your testing environment and preference.
Intelligent Triggering
Multiple trigger modes for stable waveform capture.
Trigger on edges, pulses and other signal features.
Capture the exact events you need to analyse.
High-Voltage Protection
Input protection up to 400V.
Work safely with higher voltage circuits.
Protection gives peace of mind during measurements.
Waveform and Data Storage
Store up to 500 waveform data sets.
Save up to 90 screenshot images.
USB data export for analysis on a computer.
Generate reports and documentation easily.
Review saved waveforms later without repeating measurements.
Fast Charging Battery
Built-in rechargeable battery for portable use.
QC 18W fast charging.
Full charge in approximately two hours.
Work away from mains power when needed.
Portable Tablet Design
Compact and lightweight compared to traditional bench equipment.
Take it to the lab, production line or field service site.
Touchscreen interface works like a modern tablet.
No bulky knobs and buttons.
Who Is This For?
Engineers developing and testing electronic circuits.
Technicians maintaining and troubleshooting equipment.
RF specialists analysing high-frequency signals and interference.
