Hi,
I am a beginner and recently purchased an SDS2202X-E oscilloscope. I am testing a simple RC circuit with a 10kOhms resistor and a 470uF capacitor, the time constant for this setup should be 4.7 seconds, so I want to set my oscilloscope to about 500ms per division so I can see the proper charge/discharge cycle, but my oscilloscope becomes very slow, shows a loading bar and the text acquiring, but it still doesn't show the expected waveform, it just a straight line on the level of the charged capacitor.
I believe I am doing something wrong but I don't know what it is, I am just starting out new. I need help.
