4.1 Instrumentation

The set up used for the current consumption measurements is illustrated in Figure 2. Although a LAUNCHXL-CC26X2R1 LaunchPad was used for the ZC, any Zigee 3.0 profile compatible ZC device could be used.

The ZC Light Sink example is plugged into a computer for easy configuration of commissioning. For more information, see the ZC Light Sink README document in the Z-Stack User's Guide[6]. The ZED Switch that is used for measuring current consumption, is connected directly to the DC Power Analyzer, being powered with 3.3 V. To ensure accurate current consumption measurements for the CC2652R, all jumpers are removed so that only the CC2652R is being powered, as shown in Figure 3.

For getting a GPD to be commissioned into a Zigbee network, a Green Power Sink (GPS) application is required. For either setup, the ZC uses the Light Sink example. For more information on Green Power, see the Green Power Device Application Overview section inside the Z-Stack User's Guide[6].
