Displaying Traces
To Position and
Scale Each Trace
The selected trace can be positioned vertically on the display. This is accom-
plished using the REF LEV|POS softkey to enter both the reference position and
reference level. The reference position (POS) is entered as a percentage of the verti-
cal display. The top of the screen is 100%. The bottom of the screen is 0%. The ref-
erence level (REF LEV) is the amplitude value at the reference position.

To Average Trace

The Traces menu’s average softkey presents a menu used for controlling trace

ues on each sweep. You can set the averaging count; its default value is 16.
Trace averaging is only applied to trace 1.
