Operating the Reader Using the ReaderStart Software
16.13 Spectral Scan
It may happen that the RFID transmission to or from the transponder is disturbed by frequency interfering. SpectralScan
shows a qualitative frequency spectrum. Due to the fact that it is received by means of the connected RFID antenna,
the frequency assignment on location is made visible.

If there is more than one reader, spectral scan shows which channels might be occupied by other readers. In
,p.137,
the channels 4, 10 and 13 are occupied by other readers. If the user is not satised with the reading results and the
interferences keep occurring, it is possible to deactivate channels on which the interference occurs (4, 10 and 13) and
only activate the channel that is free (7) to achieve better reading results, see ⑯ in Fig. 66 .
