● Time interval
Specifies the time after which the radiated power is increased by the dB value increment
during the measurement.
Note that with a large number of transponders and inventory can take several seconds.
Select a suitably large time interval to make sure that several inventories can be taken. If
the time interval selected is too short this can mean that the power is increased already
before the end of the inventories.
● Channels
Specifies which channels should be used in the measurement.
After you have started the measurement, all the transponders identified by the reader are
listed in the table (max. 500). Select the "EPC-ID in ASCII format" check box to display the
EPC-IDs of the transponders in ASCII code.

/ Selection of the transponders to be displayed in the graph.
Up to 10 transponders can be selected. The selected transponders are shown
in the RSSI graph as continuous lines. Up to 10 further transponders from the
list are displayed as dots.
/ / Filter status of the transponders
• Transponder was identified and returned to the user application.
• Transponder was identified but filtered out. Place the mouse pointer over
the symbol to find out which filter filtered out the transponder.
• Transponder was identified and not filtered out. However the transponder
has not yet been returned to the user application (e.g. due to the
"Glimpsed" status).
ID of the identified transponder
Antenna with which the transponder was detected.
Polarization of the antenna
Min. power Minimum radiated power [dBm] of the antenna with which the transponder was
Power Radiated power [dBm] of the antenna with which the transponder was last
Last measured RSSI value of the transponder
RSSI min. Minimum RSSI value of the transponder. Calculated over all successful inven-

Number of inventory replies (scans) of this transponder.
Time stamp when the transponder was identified the first time.
The value "Min. power" of the transponder last selected in the transponder list is
automatically transferred to the "Accept power" box with 2 dB added. By clicking the "Apply"
