 Sandbox5 consists of two nodes, i.e. node1-1 and node1-2. Each individual node is connected to one Gnuradio motherboard, and each motherboard in turn has two BasicRX and two BasicTX mounted on it, as show in the following picture.

 The frequency that the BasicTX operates on ranges from 2 MHz to 200 MHz, and the BasicRX can receive from 2 MHz to 300+ MHz.

 What we observe in the above plot is not a perfect sine wave. There are some high frequency components around the 10KHz sine wave. This is because that we set the target frequency as 1MHz, which is out of the working range of BasicRX and BasicTX. Recall that the working range of BasicRX and BasicTX is from 2MHz to 200MHz+. Now let’s try to set the correct frequency.
