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 occu r between
sample clocks, an overrun error will occur.
Note (NI USB-634x/635x/636x Devices) X Series USB devices do not support
hardware-timed single point (HWTSP) operations.
For information about connecting counter signals, refer to the Default
Counter/Timer Pinouts section.
