Graphical User Interface Controls
Part Number Selection
The drop down control (
) allows the user to select the type of attenuator to control. To evaluate the
PE43650, ensure PE43650 is selected. The device information section is updated when the selected device is
changed.
Device Information
The device information area displays some basic information about the device that has been selected. Infor-
mation consists of interface type, maximum attenuation, number of digital bits, and attenuation step size.
Latched Parallel and Serial Mode
The DSA application software supports both serial and latched parallel device modes. Select the desired mode
by choosing either “Latched Parallel” or “Serial” on the left side of the application. Ensure that the P/S switch
position on the evaluation board matches the selection in the graphical user interface.
The Send button changes functionality based on the control interface mode. Send Latch in Latched Parallel
mode and Send Signal in Serial mode are provided to resend the programming bits to the device at the same
attenuation state.
