Evaluation Board for F1956 7-bit Digital 步 Attenuator
The F1956EVBI is a fully populated evaluation board which allows the customer to easily evaluate the F1956 digital 步 attenuator. Attenuation may be set using either the F1956’s parallel control input or its serial control input. A dip switch on the evaluation board allows one to set the attenuation 状态 without off-board connections to the control inputs.
The F1956EVS is a complete hardware and software solution that allows customers to digitally control the F1956EVBI with the USB output on a computer. The kit includes the F1956EVBI board, as well as a USB Digital Control Board and interface cables. The software, guides , and instructional videos are available for download/查看ing on this page.
