TP15 Remove the Antenna before starting step from 1 to 5.
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 A201 (TP15) is 20dBm ~ 25dBm
TP15 Follow steps 1 to 4 of (H) above.
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.)
- Follow steps 1 to 4 of (H) above.
5.Confirm that the frequency offset is < ± 40kHz.
- Follow steps 1 to 4 of (H) above.
5.Set DECT tester power to -88dBm.
6.Confirm that the BER is < 1000ppm.
- Follow steps 1 to 4 of (H) above.
5.Confirm that the Timing accuracy is < ± 10ppm.
- Follow steps 1 to 4 of (H) above.
5.Set DECT tester power to -88dBm.
6.Execute the command "readrssi"
7.Confirm: 23 < returned value < 45 (hex).
