FNIRSI-1014D is an ultra-light, ultra-versatile digital oscilloscope and function generator for beginners and advanced users. The device combines a 100MHz / 1GS/s digital 2-channel oscilloscope with storage for about 1000 screenshots and a digital DDS 12-function generator.

The FNIRSI-1014D comes with 5V power supply, USB cable, and 2 probes (1x and 10x). The oscilloscope inputs are protected against a high voltage of up to 400V.

Make sure you read the manual carefully. It contains some very important hints and instructions, especially in case you are working with higher voltage and higher frequency.
