Review: Oscilloscope and Frequency Generator - A little tricking to learn to use and easy enough. Works well and render good info in the graphing. Great price.
Review: Great Tool! - Slick little product. It gets a job done. Not all the jobs maybe, but a job, certainly. The frequency generator is a nice have, and the fact that it will run independent of the scope side is great, and makes it a truly useful piece of test equipment to have. I don't know what the actual adapter is for the cable, but it would be nice to have something a bit nicer than common alligator test clips for signal injection, though, you can always clip it to a dupont cable if needed. Also, the value for cost is absurd. worth double.

## Questions & Answers

**Q: What are the steps for upgrading the firmware?**
A: A: On a Windows 10+ PC, power off the device, hold Wheel + Power, connect via Type-C, then copy the firmware file to the “IAP” drive.

**Q: What are the troubleshooting steps for an oscilloscope that won't power on?**
A: 1. Charge with a 5V/1A adapter for 1–2 hours, then hold the power button 3–5s to rule out low battery.

**Q: My oscilloscope won't trigger on signals shorter than 1µs in single-shot trigger mode. What can I do?**
A: 1. Increase pulse width (>1µs) to improve trigger recognition and stability.

**Q: How do I export an oscilloscope's waveform image?**
A: 1.Access the oscilloscope's [System Settings] menu;

### ⭐⭐⭐⭐ Signal generator works at 50kHz, solid scope for the money
*by M***S on July 1, 2025*

Solid pocket oscilloscope for $41, but keep in mind that it's a $41 scope. As with most scopes, the controls are confusing until you learn them. It's definitely not the most accurate, but it's a quick and easy way to see a waveform's shape and detect transients. Read the manual to learn how to set it up. It's good for basic automotive diagnostics. The signal generator does in fact operate up to 50 kHz, but as soon as you return to Oscilloscope mode the frequency turns back down to 1 kHz, perhaps due to lack of processing power or perhaps for driving the probe calibration signal. People complaining that the signal generator doesn't work above 1 kHz must be trying to measure the frequency simultaneously using this same device. Also note that the signal generator's actual output frequency is less accurate at higher frequency setpoints, with the most heinous error being an output of 44.4477 kHz at a setpoint of 44.000 kHz (see attached pictures); output is dead-on at 40.0 and 50.0 kHz, though. Signal generator voltage outputs are also not completely accurate (note 2.54V p-p measured at a setpoint of 3.0V p-p). This is good for learning and basic diagnostics, but rely on something more powerful for the high-importance troubleshooting. It can trigger on transients, though.
