Workstation for Microwave Digital Communications — MOE Lab Tender Details

Workstation for Microwave Digital Communications

The workstation makes use of training panels with safety sockets and cables. Each unit consists of a front panel, a PCB-board and a back cover. The panels are easily placed in a mounting frame. Thus, simply configuration and alteration in the experiment setup are possible.
