Remove the Antenna before starting step from 1 to 4.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• Test mode: PP
• RFPI: 0102030408
• Traffic Carrier: 5
• Traffic Slot: 4
• Mode: Loopback
• RF LEVEL=-80dBm
2. Execute the command "regcmd60 01 02 03 04 08".
3. Initiate connection from DECT tester.
4. Confirm that the NTP value at TP601 is 20dBm~25dBm.
-
Follow steps 1 to 3 of (I) above.
4.Confirm that the B-Field Modulation is 360kHz/div~380kHz/div using data
type Fig 31.
5.Adjust the B-Field Modulation if required. (Execute the command "Readmod"
and "wrtmod xx", where xx is the value.)
-
Follow steps 1 to 3 of (I) above.
4.Confirm that the frequency Offset is < ± 45kHz.
-
Follow steps 1 to 3 of (I) above.
4.Confirm that the frequency Drift is < ± 30kHz/ms.
-
Follow steps 1 to 3 of (I) above.
4.Set DECT tester power to -88dBm.
5.Confirm that the BER is < 1000ppm.
