How do you not destroy an oscilloscope?
Do not exceed the stated voltage. Always set the scale to its maximum setting before changing any inputs, to prevent overdriving the oscilloscope. Avoid damage by being prepared with some idea of the signal level to be connected with the oscilloscope. Overdriving the inputs can damage the front-end components.
How do you ground an oscilloscope?
Ground your oscilloscope by plugging its three-pronged power cord into an outlet grounded to earth ground. Grounding the oscilloscope is necessary for safety. If a high voltage contacts the case of an ungrounded oscilloscope—any part of the case, including knobs that appear insulated—it can give you a shock.
Can you change the voltage on an oscilloscope?
Any voltage less than that will not damage the scope, but what you see on the display may or may not be useful, depending on the settings. You can use a 10× probe to measure higher voltages — up to whatever the probe is rated for — but if you ever switch the probe to 1× while doing so, you’ll be violating the scope specification.
Why is the ground clip on my oscilloscope short?
The ground clip on your o-scope is actually tied to ground. it is a hard short and rather low resistance. This means that you are shorting the 3.3 rail to ground with your ground probe.
Why does an oscilloscope need a power brick?
If you can supply it from a battery or double-insulated power brick, you should be able to connect any single point to the scope probe’s Earth ground without affecting the functionality. Maybe another channel is already tied up to the real ground of the system, of the scope is sharing the same real ground in another way.
How are probes used in an oscilloscope?
Put the resistor in the return path so that one side of it is ground. That way the ground probe does not hurt it. Use two probes, one for each side of the resistor and use the math function on your O-Scope. Let me know if this is not clear. I can add more information.
