swaps the traces so that the “processed” trace is in front of the Normal trace – see
section 4.6.3.1.
creates a pop-up menu that enables the number of sweeps averaged to be set
between 2 and 48
.
returns to the first set of actions keys as detailed above.
4.6.3.1 Dual Trace Mode
When the trace writing mode is set to Peak Hold or Average, a dual trace mode can be selected
whereby the processed and un-processed traces are displayed simultaneously.
When first selected, the processed trace (Peak Hold or Average) will be shown in yellow with
the un-processed (Normal) trace shown in green in front of it. Pressing Swap Traces changes
this so that the processed trace is shown in green with the un-processed trace in yellow.
The green trace is always at the front and represents the true live trace. The yellow trace is
updated only at the end of each sweep which can result in it lagging the green trace.
Markers operate only on the green trace. Store functions (Store Trace and Log Trace) operate
only on the green trace.
4.6.4 Storing and Recalling Traces and Screen Images
Traces or complete Screen Images can be stored as files under automatically
incrementing names or user assigned names. Creates a set of bottom-row function
keys as follows:
enables the Live trace, the View trace, or a complete screen image, to be saved as
a file. See section 5.1 for a full description of the Store function.
enables a stored trace to be recalled to the Reference trace on the screen. The Ref
trace is purple and is always behind both the Live trace and the View trace. Recall
also enables stored screen images to be viewed. See section 5.2 for a full
description of the Recall function.
