ANT1 Short ANT1 pattern to GND.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• Test mode: FP
• Traffic Carrier: 5
• Traffic Slot: 4
• Mode: Loopback
• PMID: 00000
• RF LEVEL = -70 dBm.
2. Execute the command "sendchar TST".
3. Execute the command "sendchar dmv 2 2".
4. Check that "Signalling Status" has been set to "Locked", then press "ACCEPT
RFPI".
5. Initiate connection from Dect tester ("set up connect")
6. Execute the command "ANT1".
7. Confirm that the NTP value at ANT is 18.5 dBm ~ 25.0 dBm.
ANT1 Follow steps 1 to 6 of (H).
7.Confirm that the B-Field Modulation is -350 ± 50/+350 ± 50 kHz/div using data
type Fig31.
ANT1 Follow steps 1 to 6 of (H).
7.Confirm that the frequency offset is < ±20 kHz.
ANT1 Follow steps 1 to 6 of (H).
7.Set DECT tester power to -88 dBm.
8.Confirm that the BER is < 1000 ppm.
ANT1 Follow steps 1 to 6 of (H).
7.Confirm that Power RAMP is matching.
- 1. Link with Handset which is connected to Line Simulator.
2. Set line voltage to 48 V and line current to 50 mA.
3. Input -45 dBm (600 )/1 kHz to MIC of Handset. Measure the Level at Line I/F
and distortion level.
4. Confirm that the level is -3 dBm ± 5 dB and that the distortion level is < 5 % at
TEL Line (600  Load).
5. Input -20 dBm (600 )/1 kHz to Line I/F. Measure the Level at Receiver of
Handset and distortion level (Receive volume set to second position from
minimum).
6. Confirm that the level is -29 dBm ± 4 dB and that the distortion level is < 5 %
at Receiver (34  Load).
1. Connect Charge Contact 12 /2 W resistor between charge+ and charge-.
-
2. Measure and confirm voltage across the resistor is 3.9 V ± 0.4 V.
- 1. TAM Confirmation (Execute the command "sendchar VPI").
2. Confirm the returned Value (Value is "DER7EA 00").
