Items
(A) Charging Check
Note:
After the measuring, suck up the solder of TP.
The connection of adjustment equipment is as shown in Adjustment Standard (Charger Unit) (P.50).
Check
Point
- Follow steps 1 to 6 of (J).
ANTI_TP 7.Set DECT tester power to -90 dBm.
8.Confirm that the BER is < 1000 ppm.
- Follow steps 1 to 6 of (J).
ANTI_TP 7.Confirm that the Timing accuracy is
• ± 5.0 ppm (When adjust the frequency of CLK in item (G)).
• ± 15 ppm (When do not adjust the frequency of CLK in item (G)).
- Follow steps 1 to 6 of (J).
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 Ω)/1 kHz to MIC of Handset. Measure the Level at Line I/F
and distortion level.
4. Confirm that the level is -1 dBm and that the distortion level is <5 % at TEL
Line (600 Ω Load).
5. Input -20 dBm(600 Ω)/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 -23.5 dBm ± 4 dBm and that the distortion level is
<5 % at Receiver (34 Ω Load).
1. Connect Charge Contact 12 Ω/2 W resistor between charge+ and charge-.
-
2. Measure and confirm voltage across the resistor is 3.9 V ± 0.4 V.
VDD2 1. Confirm that the voltage between test point VDD2 and GND is 2.5 V ± 0.2 V.
Check
Point
1. Connect Charge Contact 12 Ω/2 W resistor between charge+ and charge-.
-
2. Measure and confirm voltage across the resistor is 3.5 V ± 0.3 V.
