1.
Frequency
If you select "Frequency" to be the readout type, the "Position" and the "Fixed"
marker modes display the absolute frequency; whereas the "Delta" marker
mode displays the frequency difference between the Delta marker and the
reference marker. In non-zero span mode, the default readout is "Frequency".
2.
Time
If you select "Time" to be the readout type, the "Position" and the "Fixed"
marker modes display the time difference between the marker and the start of
the sweep; whereas the "Delta" marker mode displays the sweep time
difference between the Delta marker and the reference marker.
In zero span mode, the default readout is "Time".
3.
I/Time
If you select "I/Time" to be the readout type, it displays the reciprocal of sweep
time difference between the Delta marker and the reference marker. When the
time difference is zero, the reciprocal is infinite, and "---" is displayed.
4.
Period
If you select "Period" to be the readout type, the "Position" and the "Fixed"
marker modes display the reciprocal of the marker frequency; whereas the
"Delta" marker displays the reciprocal of the frequency difference. When the
frequency difference is zero, the reciprocal is infinite, and "---" is displayed.
Readout Auto
Enables or disables the readout auto function.
Remarks:
When you enable the function, if the trace is the frequency-domain trace, then
the readout mode is frequency.
If the marker is in auto reading state, and the marker trace changes, then the
readout mode should be re-determined based on the destination trace.
If the readout mode of X-axis is manually set, then the X-axis value will not
change with the trace.
Line State
Enables or disables the marker line.
Remarks:
When you enable the marker line, a cross line is displayed at the amplitude point
where the marker resides. The width of the horizontal line and the height of the
vertical line are consistent with the length and height of the graticule in the
