- | The total counteractive force to the flow of electrons through a system is known as impedance.

This can be abstractly thought of as the resistance of the circuit, and can be measured with an impedance analyzer. The reality is that no real components, resistors, capacitors, or inductors, are purely resistive or reactive. Every component in existence is a combination of R, C, and L aspects; the unwanted aspects are called parasitics. |
- | At low frequencies and in simple applications these parasitics can usually be safely ignored, but in high speed applications or setups with specific frequency requirements, | + | At low frequencies and in simple applications these parasitics can usually be safely ignored, but in high-speed applications or setups with specific frequency requirements, |

- | The Impedance Analyzer tool from Waveforms accepts two different arrangements for the load of interest and the reference resistor. In both cases the first WaveForm Generator tool (WaveGen 1) as well as the positive inputs of both Oscilloscope inputs are used; the WaveForm Generator and the Oscilloscope tools will be shown as //Busy// when the Impedance Analyzer is in use. The two physical arrangements for the impedance analyzer are shown in the two images below: | + | The Impedance Analyzer tool from Waveforms accepts two different arrangements for a load of interest and the reference resistor.
