is generated in successive sweeps.
3. Min Hold
Maintain the minimum for each point of the trace, and update the trace point if a new minimum is
generated in successive sweeps.
4. Freeze
Stop updating the trace data to observe the trace and read the measurement data. This type is
generally used by traces loaded from storage devices or remote interface as default.
5. Blank
Disable the trace display and all measurements of this trace.
Average Times
Set the number of averages of the selected trace.
Key Points:

highlighting the stable signal characteristics. The larger the number of averages is, the
smoother the trace will be.
• You can use the numeric keys to modify this parameter, please refer to “ Parameter Setting ”
for more details.
