Agilent Technologies 4294A - Selecting Target Trace (Data or Memory) for Marker Analysis

Analysis and Processing of Result
Selecting target trace (data or memory) for marker analysis
Selecting target trace (data or memory) for marker analysis
The Agilent 4294A provides the data trace and memory trace for both trace A and trace B,
which you can use to display measured data. Note that, in the preset setting, the target for
the analysis using the maker is the data trace (all operations such as moving the marker and
displaying data are applied to the data trace). This is because the target trace for marker
analysis is the data trace in the preset setting.
Only when the memory trace is displayed on the screen can you select the target trace for
marker analysis by following these steps.
Step 1. Activate the trace you want to analyze.
Step 2. Press the
[Marker] key to display the Marker menu.
Step 3. Press the
MKR ON [ ] key to select the marker analysis target trace (pressing the key
toggles your selection).
NOTE If the memory trace for the active trace in marker analysis (trace A or trace B) is not
displayed, the target trace is automatically set to the data trace. You cannot change this
setting. For how to use the memory trace, refer to “Trace-based Comparison and
Calculation” on page 179.
