Point
- Follow steps 1 to 3 of (I).
4.Confirm that the frequency Drift is < ± 20 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 50 mA.
3. Input -45 dBm (600 Ω)/1 kHz to MIC of Handset. Measure the Level at Line I/F
and distortion level.
4. Confirm that the level is -2.0 dBm and that the distortion level is <5%
Line (600 Ω Load).
5. Input -20 dBm (600 Ω)/1kHz 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 -24 dBm and that the distortion level is <5% at
Receiver (34 Ω Load).
- 1. Link to Base which is connected to Line Simulator.
2. Set line voltage to 48V and line current to 50 mA.
3. Set the handset off-hook using SP-Phone key.
4. Input -30 dBm(600 Ω)/1 KHz to Line I/F and measure Receiving level at SP+
and SP-.
5. Confirm that the level is -8.0 dBm and that the distortion level is < 5%.
(Val = Max at SP (8 Ω Load))
CP3.0V 1. Confirm that the voltage between testpoint CP3.0V and GND is 3.0 V - 0.1/+0.3
V.
CPV2 1. Confirm that the voltage between testpoint CPV2 and GND is 3.0 V ± 0.3 V.
(Power is supplied when LED in on)
CP2.8V 1. Confirm that the voltage between testpoint CPV2.8V and GND is 4.0 V ± 0.3 V.
