44. :CALCulate:MARKer<n>:X:CENTer
Syntax :CALCulate:MARKer<n>:X:CENTer <param>
:CALCulate:MARKer<n>:X:CENTer?
Function Sets the X value at the center of the reference marker and the delta
marker in “Span Pair” marker mode, the default unit is Hz, such as
:CALC:MARK1:X:CENT 405000000 or
:CALC:MARK1:X:CENT 405MHZ
The query returns “405000000”.
Explanations

<n> is 1, 2, 3 or 4.

<param> is within the range of X.

45. :CALCulate:MARKer<n>:X:POSition
Syntax :CALCulate:MARKer<n>:X:POSition <integer>
:CALCulate:MARKer<n>:X:POSition?
Function Sets the position of the “Normal” marker on the trace, such as
:CALC:MARK1:X:POSition 100
The query returns “100”.
Explanations

<n> is 1, 2, 3 or 4.

For the range of <integer>, refer to “[:SENSe]:SWEep:POINts”.
46. :CALCulate:MARKer<n>:X:POSition:CENTer
Syntax :CALCulate:MARKer<n>:X:POSition:CENTer <param>
:CALCulate:MARKer<n>:X:POSition:CENTer?
Function Sets the position of the center frequency of “Span Pair” marker on
the trace, such as
:CALC:MARK1:X:POS:CENTer 200
The query returns “200”.
Explanations

<n> is 1, 2, 3 or 4.

For the range of <param>, refer to “[:SENSe]:SWEep:POINts”.
47. :CALCulate:MARKer<n>:X:POSition:SPAN
Syntax :CALCulate:MARKer<n>:X:POSition:SPAN <param>
:CALCulate:MARKer<n>:X:POSition:SPAN?
Function Sets the number of points on the trace. The trace is limited by the
