Figure 13.12 Lets proceed now with the device measurement. Connections need to be changed as in Fig. 13.13. We are going to measure now the voltage across Rs, which is proportional to the current in the device. Leaving anything in the Sinusoidal menu as it was for the previous measurement we obtain Fig.13.14. It seams a strange shape if you are not used to. But in fact we are measuring Current here and, Voltage being constant, it decreases at resonance.

Leaving the last measure in memory, open the Processing Tools Dialog from within Sinusoidal (MLS has the same), select the CV icon and input the data you should know. The Ohm value is that of the Sensing Resistor while in the edit box you see the name of our previous file, cvreference.sin, added by its own path which could be different in your case. 134 Chapter 13 - Measuring impedance and T&S parameters
Pressing Ok we get Fig.13.15 which is our final result. Note that the Y Units have been changed to Ohm. This result is only in memory and should be saved now for further use. 50.0 CLIO 180.0 Ohm Deg 40.0 108.0 30.0 36.0 20.0 -36.0 10.0 -108.0 13.5.2 CONSTANT CURRENT 0.0 -180.0 10 Hz 100 1k 10k 20k Figure 13.15 We will go quicker now as its very similar to what we have just seen. Connections for creating the reference are the same, please refer to Fig.13.11. Again everything should be left unchanged between creating the reference and the device files. The big difference from before is the output level. We choose here a 1Kohm resistor. This will attenuate a lot the signal at loudspeaker terminal. Fig.13.16 shows the reference measurement. 30.0 CLIO 180.0 dBV Deg 20.0 108.0 10.0 36.0 0.0 -36.0 -10.0 -108.0 -20.0 -180.0 10 Hz 100 1k 10k 20k Figure 13.16 We have a straight line again; notice the level has became 17dBV now. We change connections, accordingly with Fig.13.17, and nothing else.
