Choosing between the FNIRSI DS215H and the FNIRSI 1014D means deciding what kind of oscilloscope and signal generator combo will serve you best. One of these is built to travel, while the other offers a larger view of the signals you're chasing. Both are dual-channel tools that combine waveform capture and signal generation in a single unit, but they're aimed at different work habits: one is a grab-and-go companion, the other a more expansive bench presence. The right pick depends on how much bandwidth you need, how large you want your waveform display, and where you plan to do your measuring.
Quick verdict
If portability matters most, the FNIRSI DS215H is the practical pick. If you need more measurement reach and a wider on-screen view, the FNIRSI 1014D is the stronger choice.

Product notes
FNIRSI DS215H Oscilloscope Handheld Dual-Channel 2-IN-1 Digital Signal Generator
The DS215H is a true handheld scope with a 3.5-inch IPS HD display and a 1500mAh battery, making it easy to take from bench to field. It captures waveforms with 50MHz analog bandwidth and a 250MS/s sampling rate, which is a realistic match for audio, power, and control-circuit work. The built-in signal generator covers 13 waveform types from 0-50kHz with adjustable frequency, amplitude, and duty cycle. You can also save screenshots for later review, and the unit supports peak voltage measurements up to ±400V for higher-voltage circuits. The input resistance is 1MΩ, and coupling modes include AC and DC. The main limitation is the smaller screen and more modest bandwidth if you plan to work with faster digital signals or want a bigger waveform view.
FNIRSI 1014D 7" LCD 2 Channel Signal Generator Digital Storage Oscilloscope H0V2
The FNIRSI 1014D doubles the analog bandwidth to 100MHz per channel and raises real-time sampling to 1GSa/s, making it better suited to higher-frequency measurements. Its 7-inch TFT LCD provides a roomy view of complex waveforms. The built-in DDS signal generator outputs 14 standard function signals and can also produce a customizable chopping signal, storing up to 1000 tailored waveforms. USB picture export gives you a convenient way to capture results. With an 8-bit ADC and a horizontal time base range from 50S/div down to 10nS/div, it's a more capable measurement platform. Input resistance is 1MΩ, and coupling modes cover AC and direct current. The trade-off is a larger physical footprint that makes it less portable than the handheld DS215H.
Final choice by use case
Pick the FNIRSI DS215H when you want a portable, battery-powered scope/generator combo and your signals stay within its measurement range. Pick the FNIRSI 1014D when you need more measurement reach, a bigger display, and a faster sampling platform for detailed waveform work.
