How to Use a Fixed Reference Marker
By default, delta markers refer to marker 1. However, they can also refer to a fixed ref-
erence marker.
How to Define and Move a Fixed Reference Marker
1. To display a fixed reference marker, do one of the following:
● Press the MKR FUNC key, then select the "Reference Fixed" marker function.
● In the "Marker" dialog box, in the "Reference Fixed" area of the "Marker Config"
tab, set the "State" to "On".
A vertical and a horizontal red display line are displayed, marked as "FXD". The
normal marker 1 is activated and set to the peak value of the trace assigned to
marker 1, and a delta marker to the next peak. The fixed reference marker is set to
the position of marker 1 at the peak value.
2. To move the fixed reference marker, do one of the following:
● Change the "Level" and "Frequency" of the reference point in the "Marker Con-
fig" tab of the "Marker" dialog box, . By default, the current peak value of trace
1 is set.
● Set the fixed reference marker to the current peak value by selecting the "Peak
Search" button in the "Marker Config" tab of the "Marker" dialog box.
● Move the "FXD" display lines that define the position of the fixed reference
marker by dragging them on the screen.
