Adjustment
Point
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 (I) 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 (I) above.
5. Confirm that the frequency offset is < ± 40kHz.
- Follow steps 1 to 4 of (I) above.
5. Set DECT tester power to -88dBm.
6. Confirm that the BER is < 1000ppm.
- Follow steps 1 to 4 of (I) above.
5. Confirm that the Timing accuracy is < ± 10ppm.
- Follow steps 1 to 4 of (I) above.
5. Set DECT tester power to -88dBm.
6. Execute the command "readrssi"
7. Confirm that the returned value is 0x34 ± A (hex).
TP15 1. Configure the DECT tester (CMD60) as follows;
<Setting>
· Test mode: PP
· Mode: Nomal
· RFPI: 0102030405
2. Execute the command "testmode".
3. Execute the command "regcmd60"
4. Initiate connection from DECT tester.
5. Execute the command "openaudio".
6. Confirm that the value of EEPROM address "F3F" is "02". (If the value is not
"02 (by User)", set "02" and power off and power on, and return to clause 2.)
7. Input audio signal (50mVrms/1kHz tone) from DECT tester.
<DECT tester setting>
· Scramble: On
· AF Gen to ADPCM: On
· AF Meter Input: AF Voltm
· AF Gen Frequency: 1000Hz
· AF Gen Level: 50mVrms
8. Confirm hearing tone: 300mV ± 250mV (Just check Audio path)
9. Confirm that the audio distortion with DECT tester is < 5 %.
