Analog Input Timing Diagrams
The following sections describe the timing specifications and timing of the triggers and clock
signals related to the analog input timing engine:
• Input Timing—Input timing relates to any signal external to the M Series device that is used
as a clock or a trigger. This timing describes the delays involved with importing the external
signal into the device.
• Internal Timing—Internal timing describes the relationship between internal signals. In
general, how the input and other internal signals get used to generate output signals, such
as the convert signal.
• Output Timing—Output timing refers to the timing parameters related to exporting signals
internal to the device to a terminal for external use.
Figure B-1 is a simplified model of the M Series analog input timing engine.
