Test T5: Power Consumption of the module

Objective


This test will measure the current consumption of the module.

Equipment Required

2 laptop computers running Windows2 copies of TI SmartRF Studio software2 copies of TI SmartRF Flash Programmer2 USB cables (Type A to Type B)2 TI CC Debuggers2 Mid-Range RF modules1 External Power Supply1 Oscilloscope1 Oscilloscope ProbePrototype boardResistor 10Ω

Location

EE Lab

Procedure:

Figure 14: Measurement Setup

The current consumption varies rapidly and to estimate the maximal current consumption, the current is measured with an oscilloscope voltage probe over a 10Ω resistor in series with the power supply. The use of the resistor and oscilloscope allows measurement of the current consumption as a function of time, and is therefore necessary to calculate battery life time.

This method also gives a visual representation of the current consumption during active and sleep mode of the device.

Note: This measurement method may influence the result because of the voltage drop over the resistor and the stray (cable) resistance. Ideally the measurement setup should have been verified with a high precision amperemeter. However the accuracy will be defined by other factors and a higher accuracy here would not affect the final results. The results are also read manually from the oscilloscope, which will also influence on the accuracy.
