Marker
auto setting for time domain traces. In a delta-marker mode it is the (sweep) time interval between
the two markers.
Key Path Marker, Properties, X Axis Scale
Example CALC:MARK2:X:READ TIME sets the marker 2 X Axis Scale to Time..
Notes 1-of-N readback is Time
Couplings Frequency domain traces taken in FFT mode have no valid time data. Therefore when Time is
selected for markers on such traces, the X Axis value is taken as the appropriate percentage of
the displayed sweep time, which is a calculated estimate.
State Saved The X Axis Scale setting is saved in instrument state
Initial S/W Revision Prior to A.02.00
Inverse Time
Sets the marker X Axis scale to Inverse Time, displaying the reciprocal time. It is useful in a delta
mode to show the reciprocal of (sweep) time between two markers. This function is only
meaningful when on a time domain trace and in the Delta control mode. If the markers are at the
same X Axis value, the time between them is 0, so the reciprocal of sweep time is infinitely large.
The display will show “---” and a SCPI query will return infinity.
Key Path Marker, Properties, X Axis Scale
Example :CALC:MARK2:X:READ ITIM sets the marker 2 X Axis scale to Inverse Time.
Notes 1-of-N readback is Inverse Time
Couplings Frequency domain traces taken in FFT mode have no valid time data. Therefore when Inverse
Time is selected for markers on such traces, the X Axis value is undefined, shows as “---” and
returns not a number to a query.
State Saved The X Axis Scale setting is saved in instrument state

Marker Trace
Selects the trace that you want your marker to be placed on. A marker is associated with one and
only one trace. This trace is used to determine the placement, result, and X Axis Scale of the
marker. All markers have an associated trace, even Fixed markers; it is from that trace that they
determine their attributes and behaviors, and it is to that trace that they go when they become
Normal or Delta markers.
