Timing Considerations for DSA Devices

Supported Sampling Rates

Unlike some other DAQmx devices, DSA devices have both a maximum and a minimum sampling rate. Refer to the specifications for your device to determine the sampling rate range.

Other DSA Timing Considerations

DSA devices do not support the on-demand timing type. All DSA acquisitions and generations require hardware timing from a steady clock.

DSA devices do not support external clocking from arbitrary external signal sources such as encoders and tachometers. The PFI lines on DSA devices cannot accept external clocks. You can program a DSA device to use an external clock only when it is a slave in multi-device synchronized system. Refer to DSA Synchronization for more details.
