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
