Constitute a set of devices 
1. frequency regulator power: it can change the output frequency, but also to change its output voltage. 
2. excitation transformers: voltage from the coupling signal and the role of transformation, and its ratio to increase voltage. 
3. reactor: with the sample in series, constitute a LC circuit. 
4. divider: test materials were used to measure the voltage on at the same time as the feedback signal to the sampling apparatus. 
5. compensation capacitors: materials used to adjust the frequency of the test.
