![]() Inductance is the opposite: low frequencies produce a lower reactance than higher frequencies. ![]() In some cases, you only have a significant amount of one of these.įor example, in a carbon resistor, you shouldnt have very much of either type of reactance. Just about any circuit or component has three sources of impedance: the resistance, which shouldnt change based on frequency the capacitive reactance, which is due toof coursecapacitance and the inductive reactance from inductive elements. ![]() There will also be some way to monitor how much power is being taken out of the oscillator. ![]() The instrument is nothing more than a very broad band oscillator with a way to couple the output to an external circuit. Historically, they went by the name Grid Dip Oscillator or GDO.
