Pointer Adjustment

 Increment/Decrement allows to determine if the pointer sequence

will increment (positive) or decrement (negative) the pointer values.

 Periodic check box when selected, generates the pointer sequence

continuously. The pointer sequence is generated only once when the

Periodic check box is cleared. The capability to clear the Periodic

check box is only available for the following pointer sequences:

 Single pointers of opposite polarity

 Regular pointers plus one double pointer

 Regular pointers with one missing pointer

 Double pointers of opposite polarity

 Init-Cool check box when selected, generates pointer action with

three phases: initialization, Cool-down, and pointer sequence. Only the

pointer sequence is generated when the Init-Cool check box is

cleared.

 Status indicates the pointer event activity status.

 Initialization indicates that the pointer sequence test is started

and is running the initialization phase.

 Cool-down indicates that the pointer sequence test is started and

is running the cool down phase.

 Sequence indicates that the pointer sequence test is started and is

running the sequence phase; this phase runs until the Sequence is

turn off.

 Static pointer indicates that the pointer sequence is not started.

The signal generator transmits a fix pointer value.

 Pointer Value indicates the current pointer value. Available even if the

test is not started or if the sequence is not enabled.
