v61 v62 20 20 The image above shows TX_A connected to RX_B through a 50 ohm attenuator. Likewise, side B of both nodes are connected through an attenuator. The ports are connected by wires in order to minimize noise. However, both TX and RX can use actual antenna. 21 21 22 == Make sandbox5 ready, step by step.==22 == Setting up Sandbox 5 == 23 23 I assume you’ve read the tutorial about Orbit, and you know how to reserve a time slot, how to log into the nodes, and how to image the nodes.
