TDS3000C Series Oscilloscopes
Digital designers need to quickly find and analyze a
wide range of circuit timing problems. For example,
race conditions and transients can cause circuits to
perform inaccurately. The TDS3000C Series’ pulse
width trigger can help troubleshoot such situations
by triggering when a signal pulse width is less than,
greater than, equal to or not equal to a specified
pulse width.
To use the pulse width trigger to capture a
glitch:
1. In the
Trigger
