Explanation
Expansion Rate
• Expansion rate limits
The expansion rate which can be set varies according to the specified record length of the
pre-zoom waveform. The specified record length depends on the model, time axis setting,
sampling mode and trigger mode. For more details, refer to Appendix 2/Appendix 3.
The following table shows the maximum expansion rates for some record lengths.
