Great price! Works well for car audio, and the signal generator is awesome for electronics troubleshooting! They make a wireless soldiering pen that’s awesome too! Definitely gonna buy more from these guys and the tech support is on point! Review: Great selection of features for such a low price - Like most oscilloscopes, it will take some time to get used to the user interface and controls. Once you're familiar with it, the functionality is quite impressive for such a small product! All of the oscilloscope and signal generator functions I tested work well. The screen is easy to read and has adjustable brightness. Overall, I'm very pleased with this device. It's become one of my must-have items in my electrical toolbox. The instructions were not very clear about how to connect the oscilloscope probe and signal generator wires (alligator clamp type). There is a small metal adapter you must connect to oscilloscope probe before connecting it to the left port. The signal generator wires connect to the right port. ## Features - 【10 MHz Oscilloscope】FNIRSI DSO-510 handheld oscilloscope 10 MHz bandwidth, 48 MS/s sampling rate, 50 ns-20 S time base range.
