| Although you can't tell if you use a scope with a long dead time (a), this sine wave is not continuous. Occasionally, the signal source drops out--it produces only a baseline for an entire cycle. An HP 54600B with trigger hold-off simulates the long dead time. When you use a low-dead-time scope (b), the dropout in same sine wave appears clearly. The HP 54600B also acquired this waveform, but without trigger hold-off. |
