Figure 4-25, ECLT Synchronization Example
So far, the X-Instruments Synchronization fields were discussed
and described. The following describes the functions of the
buttons.
Clear All Assignments
– used to completely reset the table. Note
that only editable fields are affected by this action. Once pressed,
the table will look as shown in Figure 4-22.
Move Up
– used to change the position of a module to place it
toward the top of the group and master status. Note that this
operation affects the line that is currently highlighted.
Move Down
– used to change the position of a module so it is
placed below its current position in the group and can be used to
demote a master to a servant. Note that this operation affects a
line that is currently highlighted.
Path (LBUS/ECLT)
– is used for selecting the connection path.
LBUS specifies a VXI local bus connection and requires that the
master is plugged into the leftmost position and all servants are
plugged into adjacent slots to the right to the master module. ECLT
specifies the VXI backplane ECLTrg line synchronization mode.
For this mode, the location of the master and servant units in the
chassis is not crucial because the trigger lines run across the
backplane through all slots.
Apply
– used to prepare the instruments for the synchronization
sequence. This button must precede the activation of the
synchronization process.
Activate
–Once this button is pressed, the instruments will
synchronize in the selected groups and the master will control the
timing of the servant modules.
Close
– terminates the current session but does not change the
synchronization status.
