Hardware Timing and Software Timing
You can use hardware timing or software timing to control when certain actions, such as a device acquiring or generating a signal, occur in LabVIEW SignalExpress. With hardware timing, a digital signal, such as a clock on a device, controls the rate of timed actions. With software timing, LabVIEW SignalExpress determines the rate of timed actions using the operating system timer. Hardware timing usually is more accurate than software timing.

Note Some devices do not support hardware timing. Refer to the device documentation to determine if a device supports hardware timing. |
LabVIEW SignalExpress also supports hardware timing options, such as sample clock sharing, that you can use to synchronize devices. Timing configuration options appear on the Step Setup tab of most Acquire Signals and Generate Signals steps.
