External Input Termination
Switches S12 and S16 enable a 50-ohm termination to ground for the
external trigger and external clock inputs, respectively. The GPIB-VXI/C
is factory-configured with the termination disabled for both the external
trigger and the external clock inputs. Figure 2-3 shows the settings required
to enable or disable the termination on the external trigger. Figure 2-4
shows the settings required to enable or disable the termination on the
external clock.
