If you want to measure voltage you reach for a voltmeter. Current? An ammeter. Resistance? An ohmmeter. But what about measuring AC power? A watt meter? Usually.
Using the measurement techniques described in this application note, accurate power measurements can be made using high-performance current probes (plus voltage probes) and a compatible oscilloscope, when proper setup techniques are applied. Automated by a power measurement application, these measurements can be made even more easily …
You must be very careful when measuring voltages on the mains, especially in your country where the voltages are absolutely deadly. The …
An example of where a DC-coupled oscilloscope might be used is in measuring the output of a power supply, which generates a DC voltage. This sums up the AC-coupled vs DC-coupled oscilloscope. After understanding AC coupled vs DC coupled oscilloscope, let''s also see AC vs DC coupled termination in LVDS.
