range. When using multiple
Transponders, some messages are lost
due to the inherent collision between
them.
1. Query the Test Tag programming
parameters using
:TAG:QUERY:EXCITER k.
2. Check the value of all group T
parameters.
3. Correct the values using the group
W parameters.
4. Reprogram the Test TAg using the
command :TAG:MATCH:EXCITER k.
1. Query the Test Tag programming
parameters using
:TAG:QUERY:EXCITER k.
2. Check the value of all group T
parameters.
3. Correct the values using the group

4. Reprogram the Test Tag using the
command :TAG:MATCH:EXCITER k.
1. Run the procedure, 95 Series RFID
System - Final Test on page 5-14.
Step 2 - Set up the Carrier
Threshold for the Reader.
2. Check the RF level of the messages
received from the Test Tag; it must
be higher than (RSS+HNL+3)dBm,
that means 3dB above the carrier
threshold value.
Note
The Reader reports the RF level of the
received message only if the parameter
DLI=Y.
3. If the RF level of the Test Tag’s
received messages is lower than
-85dBm, either reposition the
Reader or Exciter, or use a higher
gain UHF antenna for the Reader.
