Pulse Trigger (WaveBook/516 Series Only)

Pulse Trigger allows the use of a high-bandwidth input for triggering, and the correlation of lower-speed

waveforms with the occurrence of a high-speed pulse. You can set a pulse amplitude between ±5 V and a

pulse width in the range of 10 ns to10

Pulse Trigger Selected

The red horizontal line (Threshold) and blue vertical lines (defining maximum width) will vary according to

the parameter settings. You can specify either one or two thresholds for the level and width settings. The

number of labels matches the number of thresholds and the placement follows the polarity.

•

For positive polarity, the text is “Rise Above... Stay Below.”

•

For negative polarity, the text is “Fall Below and Stay Above.”
