An integrated digital control interface supports both serial and parallel programming of the attenuation, including the capability to program an initial attenuation state at power-up. Covering a 31.5 dB attenuation range in 0.5 dB steps, it maintains high linearity and low power consumption from 30~40MHz through 4 GHz. BVA303/305/518 also features an external negative supply option, and is offered in a 24-lead 4x4 mm QFN package. The BVA303/305/518 Evaluation Kit (EVK) includes the application software and hardware required to control and evaluate the functionality of the DVGA using a PC running the Windows operating system to control the USB interface board Application support For any technical inquiries regarding the evaluation kit or software, please visit applications support at www.Berex.com (fastest response) or call (82)-2-568-2754.

USB Serial Converter FTDI Driver Installation For Windows 8 and 7, drivers will be installed automatically when your computer is connected to the Internet. Alternatively, you may install the drivers from the file web site download (http://www.ftdichip.com/Drivers/VCP.htm) Connect the USB Serial converter to an available USB port, and the “Found New Hardware Wizard” will guide you through the installation process. When prompted to connect to Windows Updates to search for drivers, select “No, not at this time”, and follow the instructions for installing from the file downloaded Once the drivers are successfully installed, the USB Serial converter will show up in the Windows Device Manager: Under “Ports (COM & LPT)”: labeled as “USB Serial Port (COMx)”, and under “Universal Serial Bus controllers”: labeled as “USB Serial Converter” (Figure 10-b). IMPORTANT NOTES: If it’s the first time you install the driver for CommFront’s USB to Serial device, you will need to install the driver twice. One is for “USB Serial Converter”, and the other one is for “USB Serial Port”. nd DO NOT close the 2 “Found New Hardware Wizard” window while installing the driver. Upon completion of driver installations, remember to check the Windows Device Manager to make sure that the drivers are installed properly (Figure 10-a). If the drivers are not installed correctly, there will be a yellow exclamation icon displayed under the “Ports (COM & LPT)” or “USB Serial Bus controllers”, right-click on the yellow exclamation icon and select “Update driver”.
