The F1950EVBI is a fully populated evaluation board which allows the customer to easily evaluate the F1950 digital step attenuator. Attenuation may be set using either the F1950’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 F1950EVS is a complete hardware and software solution that allows customers to digitally control the F1950EVBI with the USB output on a computer.  The kit includes the F1950EVBI 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.
