Figure 7-26 shows an example of a sample clocked buffered two-signal separation
measurement.

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
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
section.
