Stepping and scanning trigger model additions
The trigger model presented in “Trigger operations” earlier in this section has some
additional capabilities when stepping or scanning. These are outlined below:
• Timer — With this control source, event detection is immediately satisfied on the initial
pass. Each subsequent detection is satisfied when the programmed timer interval (up to
99H:99M:99.99S) elapses.
• Reading counter — For both stepping and scanning, the reading count can be entered
from SHIFT-CONFIG. (This is referred to as the trigger counter over the bus.) The
reading counter can bypass the idle state. Operation will wait until the programmed
control source event occurs.
• Channel counter — For scanning, the scan list length (maximum channel less minimum
channel) is used to bypass the control source allowing a specified number of device
actions to occur. (This counter is referred to as the sample counter over the bus.)
These additional blocks are shown in the trigger models of Figure 3-12 and Figure 3-13. Uses
of the timer control source, reading counter, and channel counter are shown in the scanning
examples later in this section.
