This is surprisingly powerful for the money, although the limited buttons require some practice to select correct modes. In Auto mode, the oscilloscope produces a clear visible trace in a few seconds. The bandwidth is around 200kHz as stated and Auto mode has difficulty around 40Hz, although I have provided a trace taken at that frequency. This makes a very useful instrument for audio and slightly higher frequencies. Coupled directly to my frequency generator, there is no overshoot or ringing on square waves. The PWM output is rated to 80kHz and fixed 5 volts, but mine produces frequencies up to 9.9MHz, but obviously more like a sine wave. The Remote tester works with all the IR remotes I have tested. There are many more setting, I have yet to test, but this is surprisingly powerful in a small package.
