Manual Reset
Averaging refers to trace averaging and this tool is used to set the number of traces that are averaged from 1 to 100.
The default state is 10 averages with automatic reset enabled. It takes 0.3 – 1.0 msec to collect one buffer of data. The
number of averages or buffers is selected from the drop down shown below. There is provision for automatic or
manual averaging reset.
Auto Reset triggers an averaging restart when the trace changes are pronounced (it assumes a new signal is being
examined). Manual Reset makes this function discretionary for the user. Shown below is an example of averaging
OFF compared to averaging set to 10 and the effect. Increasing the number of averages increases the measurement
time.
