Point
- Remove the Antenna before starting step from 1 to 4.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• • • • Test mode: PP
• • • • RFPI: 0102030405
• • • • Traffic Carrier: 5
• • • • Traffic Slot: 4
• • • • Mode: Loopback
• • • • RF LEVEL = -70dBm
2. Execute the command "regcmd60 01 02 03 04 05".
3. Initiate connection from DECT tester.
4. Confirm that the NTP value at ANT is 20dBm ~ 25dBm.
- Follow steps 1 to 3 of (K).
4.Confirm that the B-Field Modulation is -350 ~ -400/+320 ~ +370kHz/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 (K).
4.Confirm that the frequency Offset is < ± 45kHz.
- Follow steps 1 to 3 of (K).
4.Confirm that the frequency Drift is < ± 30kHz/ms.
- Follow steps 1 to 3 of (K).
4.Set DECT tester power to -90dBm.
5.Confirm that the BER is < 1000ppm.
