Page 9: Introduction
1. Introduction consists of two independent direct MOGL ARF/XRF AD9910 digital synthesizer (DDS) sources, each with 4 W amplifier. The fre- quency, amplitude and phase of each output is software-controlled via a microcontroller and (field programmable gate array). The FPGA frequency, amplitude and phase can be defined via front-panel con- trol knobs, or via ethernet or . -

3. Communications can be connected by or ethernet ( ). From the ARFx21 TCP/IP user and device perspective, the two are equivalent. 3.1 TCP/IP When ethernet is connected, the will attempt to obtain an ARFx21 address by . If fails, an internally defined address will DHCP DHCP be used. - Page 18 Chapter 3.

3.2 USB 1. Connect the ethernet directly to a computer ethernet socket, not via a network switch or hub. 2. Configure the computer network settings to have an address in the same address space as the ; for this example, you ARFx21 can set the computer address to 10.1.1.189. - Page 20 If you do not see a virtual COM port under “Ports” then manually install the driver. The driver install packages should be in ; run the appropriate 32- c:\Program Files\MOGLabs\USB_VCPdriver bit or 64-bit setup program and look again for the virtual COM port within Device Manager.
