Operation Procedure of Power Consumption Test
3.3.1.
Prepare Test Tools
The following equipment and tools are needed for the power consumption test:
⚫
A BC660K-GL-TE-B development board;
⚫
A DC power analyzer (a Keysight
N6705C
DC Power Analyzer is used in this case);
⚫
Wires, a soldering iron, tin wires and wire stripping pliers, etc. to weld the power supply cord onto the
board.
3.3.2.
Modify BC660K-GL-TE-B
If you use the BC660K-GL-TE-B to test the power consumption of the BC660K-GL module, you need to
modify the BC660K-GL-TE-B as follows:
1. Remove the jumper cap on J203 to disconnect the module from other parts.
2. Solder two wires respectively to the two pins (VBAT, GND) of J201 so that the external power supply
can supply power to the module.
