FNIRSI Handheld 2 In 1 Digital Oscilloscope 10 MHz 48MSps

Meet the FNIRSI Handheld 2 In 1 Digital Oscilloscope — a compact, portable testing companion designed for quick, accurate signal analysis on the go. With a bandwidth of 10 MHz and 48 MS/s real-time sampling, it captures both slow and fast waveforms clearly, helping you troubleshoot electronics, verify circuit behavior, and learn electronics anywhere. This 2-in-1 device combines oscilloscope functionality with built-in signal generation, making it ideal for field service, classroom demonstrations, and on-site maintenance.

Designed for reliability and ease of use, it features a bright 2.8-inch display (320×240) for clear waveforms, a single-channel input, and flexible triggering (Auto / Normal / Single). Its compact profile (99 mm × 68.3 mm × 19.5 mm) fits easily in a tool kit or lab bench, while a built-in 1000 mAh battery provides up to 4 hours of portable operation. USB charging lets you top up power from a computer or charger, so you can work longer between outlets.

Benefits & Tips

• Ideal for maintenance and education: quickly test analog and digital signals, verify timing, and demonstrate waveform behavior to students or colleagues.
• Portable field companion: take measurements anywhere with USB-powered charging and battery operation.
• Flexible measurement controls: leverage time-base from 10 μs/Div to 50 s/Div and Auto/Normal/Single triggering to capture the exact event you need.
