Measuring an aluminum electrolytic capacitor''s ESR

The scope method to measure capacitor ESR is a qualitative measurement. It gives you an order of magnitude, but it is not a precise measurement. An LCR (inductor, capacitor, resistor) bridge uses techniques, like a bridge, to measure the ESR, so it is far more accurate. However, to validate if a capacitor is "good" or not, the scope works okay.
