Demo: Loopback Test on Cyan

In this tutorial, we demonstrate a loopback test using an 8 receive and 8 transmit configuration of Cyan and a GNU Radio script. This test is used to ensure the SDR is capable of transmitting and receiving the same frequency and amplitude on all eight channels.

1. Loopback test Setup

1.1. Software requirements

  1. GNU Radio and associated dependencies must be installed on your computer

You are able to find the loopback test Cyan GNU Radio script here.

1.2. Hardware requirements

  1. Cyan SDR with associated host computer/adaptors/cables
  2. SMA cables

The figure below shows the setup of Cyan for this test.
