| + | This section is to run the server side and FPGA configuration software to take a simple observation. | ||

| + | While waiting for the storage server to be populated and configured, dsa-ata-1 has the local 8TB disk mounted in ~dsa/data for recording. The main .fil files will be stored here. The log files for data capture will be stored in ~dsa/ | ||

| - | - The power supply for the Valon, it has been ordered. For now we moved over theSG380 Signal Generator. | ||
| - | - We need 6 more SMA cables. So we have now 7 SNAPs connected to feeds. | ||
| - | - The fiber to connect the SNAPs and computers have not arrived. Using copper cables instead temporarily. | ||
