Page 13: Power Consumption Test
Power Consumption Test 4.2.1 Power Consumption in Running Mode To power the GNSS adapter, you can use an external voltage or the power from the bottom board. See 4.2.1.1 and 4.2.1.2 for the procedures to test the power consumption in the running mode with different power source. 4.2.1.1 Powered by Bottom Board When the adapter is powered by the bottom board. - Page 14 UC6580 EVK User Manual Figure 4-2 Testing Power Consumption If you just have one multimeter, you can measure the current VDDIO current DCDC_IN respectively. Make sure that when you measure either one of the current current values, the other jumper cap is installed. 4.2.1.2 Powered by External Voltage When you use the external voltage to power the adapter, the power consumption is...
