In the WICED Studio SDK, Please refer to 20719-B1_Bluetooth/wiced_tools/wmbt/readme.txt. There are some explanations about how to test and verify the RF performance.
You can get the latest SDK here: WICED Studio Wi-Fi/Combo Docs & Downloads

There are many code examples below apps/demo file in the SDK. You can try them on your board depending on your application. There are descriptions about how to demonstrate the demo in the .c file (for example, you can find how to demonstrate the hello sensor demo in the hello_sensor.c). You may start with hello sensor demo.

Please find the clientcontrol.exe under the apps/host/client_control/windows. You can find the readme.txt file about how to use it.

Do you mean the HCI mode or RF test? If you are using the HCI mode, you don't need to download the application. Just send the HCI command described in the WICED-HCI-Control-Protocol.pdf. The document is located in the doc folder in the SDK.

Hi,
In HCI mode can we able to test RF Parameters? like unmodulated carrier frequency, power etc.,
In "WICED-HCI-Control-Protocol.pdf" document commands are given with some examples, but if i wanted to test all the unmodulated carrier with different power levels where i can get the register values/ setting ?
Is their any document which gives the registers settings and how to calculate the register values for desired frequency & power levels.

Thanks . . . . . .
