:CALCulate:MARKer[1]|2|3|4|5|6|7|8:X <x-parameter>
:CALCulate:MARKer[1]|2|3|4|5|6|7|8:X?
Description: Sets the location of the marker on the x-axis at the specified location.
<x-parameter> is defined in the current x-axis units. The set command
will set the specified marker as the active marker. The <x-parameter>
given unit must correspond to the specified marker domain type. If no
unit is specified with the <x-parameter> then the default unit will be
used.
The query version of the command returns the location of the marker on
the x-axis followed by the unit. If the Start and Stop values of the
domain are the same, then the query returns the X value along with the
marker point number within the brackets. The marker point number is
determined with the following formula:
For example, if 201 points are used in the measurement display, then
the query returns: <x-value> (101). When the results of division
include a fraction, as in the current example, the result is rounded
DOWN. 201/2 = 100.5 Rounding down to 100 before adding 1
yields the 101 that is returned by the query.
If an error occurs, such as marker not ON, the query version of the
command returns an error code of –400. Note that the marker is
snapped to the data point closest to the specified value. The selected
marker must be ON for the command to be valid.
Cmd Parameter: <NRf> <x-parameter> (hertz, meters, feet)
Query Response: <NR3> <x-parameter> (hertz, meters, feet)
Default Units: Hz for frequency domain,
Meters or Feet for distance domain.
Example: To set reference marker #2 (frequency domain) to 5000 hertz on the
x-axis:
:CALCulate:MARKer2:X 5000
:CALCulate:MARKer2:X 5000Hz
To set reference marker #1 to 1.5 GHz on the x-axis:
:CALCulate:MARKer1:X 1.5GHz
:CALCulate:MARKer1:X 1.5GHz
