Figure 7-26 shows an example of a sample clocked buffered two-signal separation
measurement.
Figure 7-26. Sample Clocked Buffered Two-Signal Separation Measurement
Hardware-Timed Single Point Two-Signal Separation
Measurement
A hardware-timed single point (HWTSP) two-signal separation measurement has the same
behavior as a sample clocked buffered two-signal separation measurement. Refer to the Sample
Clocked Buffered Two-Signal Separation Measurement
section for more information.
Note If an active edge on the Gate and an active edge on the AUX does not occur
between sample clocks, an overrun error occurs.
Note (NI USB-63
xx Devices) USB X Series devices do not support
hardware-timed single point (HWTSP) operations.
For information about connecting counter signals, refer to the
Default Counter/Timer Pins
section.
Counter Output Applications
The following sections list the various counter output applications available on X Series devices:
•
Simple Pulse Generation
• Pulse Train Generation
• Frequency Generation
• Frequency Division
• Pulse Generation for ETS
