4.3. Power Consumption Test Guide
4.3.1. Test Tools
The following are the equipment and tools needed for the power consumption test:
⚫ BC950K-GL TE-B
⚫ DC power analyzer
⚫ Wire, soldering iron, tin wire, and wire stripping pliers, etc. to weld the power supply cord on
TE-B.
This power consumption test guide is based on Keysight's N6705C DC power analyzer for testing.
4.3.2. Modify TE-B
If you use the TE-B to test the power consumption of BC950K-GL, you need to modify the TE-B as follows:
1. Remove the jumper cap on J0206 to disconnect the module from other parts.
2. Solder two wires to the two pins (VBAT, GND) of J0202, one wire is used as VBAT, and the other is
used as GND, so that the external power supply can supply power to the module separately.
