Attenuators

Attenuators: Attenuators are designed to change the magnitude of the input signal seen at the input stage, while presenting a constant impedance on all ranges at the attenuator input. A compensated RC attenuator is required to attenuate all frequencies equally. Without this compensation, HF signal measurements would always have to take the input circuit RC …

Measure of Capacitance and Inductance in Oscilloscope

Measure of Capacitance and Inductance in Oscilloscope

Measure of Capacitance and Inductance in Oscilloscope: Measure of Capacitance and Inductance in Oscilloscope – Capacitance may be measured from a  capacitor discharge curve. This requires a dc oscilloscope with a triggered single sweep that is of the storage type. Figure 7.38 (a) shows the test setup. C is the capacitor under test, and E …
