Point
- Follow steps 1 to 3 of (J).
4.Confirm that the frequency Drift is < ± 30kHz/ms.
- Follow steps 1 to 3 of (J).
4.Set DECT tester power to -88dBm.
5.Confirm that the BER is < 1000ppm.
- Follow steps 1 to 3 of (J).
4.Confirm that the Timing accuracy is < ± 2.0ppm.
- Follow steps 1 to 3 of (J).
4.Set DECT tester power to -81dBm.
5.Execute the command "readrssi".
6.Confirm that the returned value is 0×1B ± 8 (hex).
7.Set DECT tester power to -63dBm.
8.Execute the command "readrssi".
9.Confirm that the returned value is 0×23 ± 8 (hex).
- Follow steps 1 to 3 of (J).
4.Confirm that Power RAMP is matching.
- 1. Link to BASE which is connected to Line Simulator.
2. Set line voltage to 48V and line current to 40mA.
3. Input -45dBm/1KHz to MIC and measure Line output level.
4. Confirm that the level is -7.5dBm ± 2dBm and that the distortion level is < 5%
at TEL Line (600Ω Load).
5. Input -20dBm/1KHz to Line I/F and measure Receiving level at REV1 and
REV2.
6. Confirm that the level is -20.5dBm ± 2dBm and that the distortion level is < 5%
at Receiver. (vol = 2)
