Page 5: Quick Start
Quick Start In this paragraph the first usage of the EV12AQ600 demonstration board is described step by step. In this example a 100 MHz sinus signal is digitized with ADC1 with 6 Gsps. Setup Hardware First the hardware has to be set up. An overview can be seen in Figure 1.
Page 6: Connect To Hardware
Connect to Hardware When the hardware is running the GUI can connect to the demoboard. 1. Run ev12aq600-gui.exe 2. Then connect to the board. Therefore fill in the host. a. Interface eth0 will always be set to DHCP, which means that it will get its IP address by a DHCP server in the local network b.

Figure 3: Trigger snapshot and analyze signal in the frequency domain This was a simple example to show the basic function of the EV12AQ600 demo board. A more detailed description of the hardware and the GUI can be found in the following paragraphs.
Page 8: Detailed Hardware Description
Detailed Hardware Description There exist two different versions of the ADC Demoboard. The v1 can be seen in Figure 4 and the v2 in Figure 5. Figure 4: detailed overview of the v1 ADC-Demoboard All information given in this document is property of Fraunhofer IIS.

Page 9: Difference V1 And V2
Figure 5: detailed overview of the v2 ADC-Demoboard Difference v1 and v2 The difference in between v1 and v2 is that v1 needs a SD-Card to work. This is not the case for v2. Here the operating system is stored inside a flash memory. The v2-Boards have also an additional button S1107.
Page 10: Rescue Procedure
Rescue Procedure This procedure is only working with v2 boards. It is needed when the connection to the ADC Demoboard can be no longer established. The procedure is as following: 1. Insert a rescue SD-Card into the ADC-Demoboard 2. Power on the ADC-Demoboard 3.
Page 11: Detailed Gui Description
Detailed GUI Description In this paragraph the menu bar and every tab of the GUI is described in detail. Menu Bar File: The current GUI-Configuration can be stored (Save Configuration) to be loaded later (Load Configuration). The loaded configuration is applied directly. Analysis: The current snapshot can be stored (Save Snapshot) or a snapshot can be loaded to be analyzed with the GUI (Load Snapshot).
Page 12: Functions
The Status-tab is the tab that opens automatically after the start of the GUI. It shows general information about the connected board. This includes temperatures, version information and hardware information. Just the temperature is updated automatically (every second). The rest has to be updated with the refresh button.

4 Set Configuration: Write the current configuration to the ADC. 5 Get Configuration: Load the ADC configuration and display it in the GUI. 6 Manual Ethernet: Changes made here only apply to Ethernet 1. If the manual Ethernet is deactivated DHCP for eth1 is active. Press Set Ethernet Settings to save changes and restart the board if IP address was changed (press Reboot-Button on Status Tab).
