Marker
Frequency
Sets the marker X Axis scale to Frequency, displaying the absolute frequency of a normal marker
or the frequency of the delta marker relative to the reference marker. Frequency is the auto setting
for frequency domain traces.
If Frequency is selected for a time domain trace, all of the points in the trace will show the same
value. Attempting to use the knob or step keys to adjust the X Axis value of the marker or
entering an X Axis value from the numeric keypad or remotely will have no effect but will generate
no error.
Key Path Marker, Properties, X Axis Scale
Example CALC:MARK2:X:READ FREQ sets the marker 2 X Axis scale to Frequency.
Notes 1-of-N readback is Frequency
State Saved The X Axis Scale setting is saved in instrument state.
Initial S/W Revision Prior to A.02.00
Period
Sets the marker X Axis scale to Period, displaying the reciprocal of the frequency of the marker, or
the reciprocal of the frequency separation of the two markers in a delta-marker mode. The units
are those of time (sec, msec, etc). If the markers are at the same frequency in a delta marker
mode, the result will be the reciprocal of 0, which is infinitely large. The display will show “---”
and a SCPI query will return infinity.
If Period is selected for a time domain trace, all of the points in the trace will show the same
value. Attempting to use the knob or step keys to adjust the X Axis value of the marker or
entering an X Axis value from the numeric keypad or remotely will have no effect but will generate
no error.

Time
Sets the marker X Axis scale to Time, displaying the time interval between a normal marker and
the start of a sweep or the time of the delta marker relative to the reference marker. Time is the
