FNIRSI 1013D Plus Oscilloscope - Portable 7ft Touchscreen

In this review of the FNIRSI 1013D Plus Oscilloscope the bottom line is clear: it is a portable, touchscreen oscilloscope aimed at hobbyists, technicians, and field engineers who need a compact tool that covers common bench tasks. The single biggest reason to buy is its combination of a responsive capacitive touch screen and a full feature set - including 1 GSa/s sampling, dual 100 MHz channels and a built-in high-voltage protection module - all in a lightweight, battery-powered package that is easy to carry between job sites.

Key Features

• 1 GSa/s sampling rate: captures fast transients and gives adequate resolution for most signal troubleshooting work without a desktop scope.
• 100 MHz dual bandwidth: two channels at 100 MHz allow side-by-side comparison and basic mixed-signal observation for many electronics tasks.
• 7 in capacitive touchscreen: a bright 800 x 480 display with gesture operation makes navigation intuitive and speeds measurements in the field.
• High-voltage protection: the built-in module tolerates continuous voltages up to 400 V, increasing safety when probing higher-voltage circuits.
• Battery and storage: the 6000 mAh battery supports about four hours of use and the 1 GB internal storage can keep roughly 1000 screenshots or waveform sets for later review.
• Waveform tools: cursors, Lissajous display and an FFT viewer provide practical analysis options without external software.

Who It's For

The FNIRSI 1013D Plus suits electronics hobbyists, field technicians, and educators who value portability and a modern touch interface over the size and polish of a lab bench instrument. Its battery life and storage make it especially useful for on-site troubleshooting and portable demonstrations.

Those who need laboratory-grade accuracy, an expansive feature set for deep signal analysis, or long-term reliability guarantees should look elsewhere; some users report mixed experiences with long-term durability and occasional functionality issues, so professionals requiring mission-critical uptime may prefer a proven bench model.

Pros & Cons

Pros

• Portable, ultra-thin design and a bright 7 in touchscreen make it pleasant to use on the go.
• Good value for money: dual 100 MHz channels and 1 GSa/s are strong specs for the price class.
• Built-in high-voltage protection and 6000 mAh battery increase safety and field usefulness.
• Waveform image manager and FFT/Lissajous displays add practical analysis features without a PC.

Cons

• Functionality receives mixed feedback from users, with a minority reporting early failures that affect reliability expectations.
• The touchscreen and screen size draw mixed opinions for fine-detail waveform inspection compared with larger bench scopes.
