Items
(I)* Transmitted Power Remove the Antenna before starting steps from 1 to 5.
Confirmation
(J) Modulation Check and Follow steps 1 to 4 of (I) above.
Adjustment
(K) Frequency Offset Follow steps 1 to 4 of (I) above.
Confirmation
(L) Sensitivity Receiver Follow steps 1 to 4 of (I) above.
Confirmation
(M) Timing Confirmation Follow steps 1 to 4 of (I) above.

Confirmation
1. Configure the DECT tester(CMD60) as follows;
<Setting>
• Test mode: PP
• RFPI: 0102030405
• Traffic Channel: 5
• Traffic Slot: 4
• Mode: Loopback
2. Execute the command "testmode".
3. Execute the command "regcmd60"
4. Initiate connection from DECT tester.
5. Confirm that the NTP value at ANT is 20dBm ~ 25dBm
5. Confirm that the B-Field Modulation is 340kHz/div ~ 402kHz/div using data type Fig31.
6. Adjust the B-Field Modulation if required. (Execute the command "Readmod" and
"Writemod xx", where xx is the value.)
5. Confirm that the frequency offset is -50kHz ~ +50kHz.
5. Set DECT tester power to -88dBm.
6. Confirm that the BER is < 1000ppm.
5. Confirm that the Timing accuracy is < ± 10ppm.
5. Set DECT tester power to -70dBm.
6. Execute the command "readrssi"
7. Confirm: 52 returned value
