Adjustment Point
CLK 1. Execute the command "conttx".
2. Input Command "rdeeprom 00 57 01", then you can confirm the current value.
3. Adjust the frequency of CLK executing the command "setfreq xx (where xx is
the value)" so that the reading of the frequency counter is 10.368000MHz ±
10Hz.
- 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 = -70dBm
2. Execute the command "regcmd60 01 02 03 04 08".
3. Initiate connection from DECT tester.
4. Confirm that the NTP value at A201 (TP15) is 20dBm ~ 25dBm.
- Follow steps 1 to 3 of (J) 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 (J) above.
4.Confirm that the frequency Offset is < ± 50kHz.
- Follow steps 1 to 3 of (J) above.
4.Confirm that the frequency Drift is < ± 30kHz/ms.
- Follow steps 1 to 3 of (J) above.
4.Set DECT tester power to -88dBm.
5.Confirm that the BER is < 1000ppm.
- Follow steps 1 to 3 of (J) above.
4.Confirm that the Timing accuracy is < ± 0.5ppm.
