GENERATION OF PULSER OUTPUT AT SW8T OF HV2916
This section provides the simple step-by-step procedure to make the Ch1 pulser output
at the SW8T SMA connector with dummy loads by configuring the GUI.
1. Before powering up the HV2916 Analog Switch Evaluation Board, make sure
that the latest GUI software is installed on the PC.
2. Start the GUI program. If the board is not connected, a “Not Connected” message
is displayed in the Status bar located at the bottom left of the screen.

0
’ to ‘
1
’ to set SW8 ON
(DIN =
00000000 00000000 00000001 00000000
).
9. Click the
Set HV MUX
button to turn on the HV2916 SW8.
