3. UG6 Only valid when WSAB is configured for 2 cell operation 2 cell operation is the default configuration 8 Current profile measurements The current sensing resistor R7 0 1 Ohm is placed in the ground path of the WSAB This provides the option of characterizing the current profile of the application simply by using an oscilloscope Measurements can be done using the solderpoints near R7 using a 1x probe Connect the probe ground to the round solderpoint and the probe tip to the square solderpoint A momentary current of 100mA will translate to 10mV on the oscilloscope Therefore the signal should be inverted in the oscilloscope channel setup The measurements can be used to profile or watch the active current consumption when developing and testing applications Due to the low value of the resistor the measurements are only valid in active states with Wi Fi activity Sleep currents are too low to measure using the current sensing resistor and should be done by other means If external circuitry is added using the expansion connector of the WSAB Docking Station it is possible to include the current consumption of added peripherals by using the GND WSAB pins in J9 as the ground return path for the external circuits In this way the total current consumption of a complete application can be evaluated User Guide WSAB Docking Station RTX4100 Wi Fi Module 13 9 Board documentation User Guide WSAB Docking Station RTX4100
