Table 4-2 provides more information about each of the timing signals
available on the PXI trigger bus. For more detailed timing signal
information, refer to Appendix B,

Table 4-2. PXI Trigger Bus Timing Signals

Direction
Input This trigger is the source for the
analog input digital start trigger,
which is the trigger that begins
an acquisition.
Output This trigger sends out the actual
analog input start trigger.
Input This signal can pause and resume
acquisition.
Input This timebase provides the master
clock from which the sample
clocks are derived.
Output This signal is output when the
analog signal to be converted by
the ADC has been held.
