The F1912EVBI is a fully populated evaluation board which allows the customer to easily evaluate the F1912 digital step attenuator. Attenuation may be set using either the F1912’s parallel control input or its serial control input. A dip switch on the evaluation board allows one to set the attenuation state without off-board connections to the control inputs.

The F1912EVS is a complete hardware and software solution that allows customers to digitally control the F1912EVBI with the USB output on a computer. The kit includes the F1912EVBI board, as well as a USB Digital Control Board and interface cables. The software, guides , and instructional videos are available for download/viewing on the page.
