such as earth ground. 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...
Frequency and period-- Frequency is defined as the number of times per second a waveform repeats. And the period is the reciprocal of that (number of seconds each repeating waveform takes). The maximum frequency a scope can measure varies, but it's often in the 100's of MHz (1E6 Hz) ...
Key Oscilloscope Specifications Some scopes are better than others. These characteristics help define how well you might expect a scope to perform: Bandwidth -- Oscilloscopes are most commonly used to measure waveforms which have a defined frequency. No scope is perfect though: they all have limits...
Step 7: Measure Frequency The frequency of a wave is the number of times per second that a wave repeats its shape. We cannot directly measure the frequency on the oscilloscope, but we can measure a closely related parameter called period; the period of a wave is the amount of time it ta...
A third method for finding the inductance of a device consists of placing the inductor in parallel with a known capacitance. The resulting tank circuit is then placed in series with a resistor and the resonant frequency is found using an oscilloscope. From this, the inductance can be calculated...
One of the reasons for using a high-resolution oscilloscope is to measure small signals. The question is sometimes asked, why not just use a lower resolution instrument and a smaller range to “zoom in” on the signal to measure small voltages? However, many signals have both a small signal...
