To start the calculation, click either on the button or activate the checkbox
. Track resonance will automatically evaluate the calculation and search the
resonance peak after each completed sweep.
As a result you should see the three cursor positioned correctly at the resonance curve and the result
in the ribbon:
Figure 11-14: Contactless resonance frequency and q-factor measurement of a 125 kHz RFID tag
The result in this example indicates a resonance frequency of 129.25 kHz and a Q-factor of 24.5.
To learn more about contactless resonance frequency and Q-factor measurements of RFID
transponders, please refer to the corresponding application note available at www.omicron-
