- Follow steps 1 to 3 of (I).
4.Confirm that the B-Field Modulation is -370±30/ +370±30 kHz/div & Modulated
width 690 kHz using data type Fig 31.
- Follow steps 1 to 3 of (I).
4.Confirm that the frequency Offset is < ± 50 kHz.
- Follow steps 1 to 3 of (I).
4.Confirm that the frequency Drift is < ± 35 kHz/ms.
- Follow steps 1 to 3 of (I).
4.Set DECT tester power to -88 dBm.
5.Confirm that the BER is < 1000 ppm.
- Follow steps 1 to 3 of (I).
4.Confirm that Power RAMP is matching.
- 1. Link to BASE which is connected to Line Simulator.
2. Set line voltage to 48 V and line current to 40 mA.
3. Input -45 dBm/1KHz to MIC and measure Line output level.
4. Confirm that the level is -8.5 dBm ± 2 dBm and that the distortion level is < 5%
at TEL Line (600 Ω Load).
5. Input -20 dBm/1KHz to Line I/F and measure Receiving level at REV+ and
REV-.
6. Confirm that the level is -21 dBm ± 2 dBm and that the distortion level is < 5%
at Receiver. (vol = 2)
