14.12 TagScan
To represent the relationship between the tag phase and the RSSI value, it is possible to plot both values by means of
the TagScan.
✔ There is only one tag in the field or a tag has been selected.
► Click Start to activate the TagScan.
➯ The phase shifts are seen in the frequency switching. The RSSI value does not change because the transponder
(tag) is not moved.
