Enables/disables the currently active limit line alarm. Setting the value to ON or 1 will turn on the limit alarm. Setting the value to OFF or 0 will turn off the limit alarm. The query version of the command returns a 1 if the currently selected limit line alarm is set to ON and returns 0 if OFF. Use :CALCulate:LIMit:TYPe to set the currently active limit line.

Set Active Limit
Description
Sets the currently active High/Low limit line.
Parameter
<value> 0 for upper limit line; 1 for lower limit line
Default Value
0
Example
To set the lower limit line active: :CALCulate:LIMit:TYPe 1
Sets the currently active limit line value. This command moves an entire single or multi-segment limit line up or down by the given <value>. This command is equivalent to the command :CALCulate:LIMit:Y. Use :CALCulate:LIMit:TYPe to set the currently active limit line.
Turns the currently selected limit line (upper or lower) ON or OFF. If the value is set to ON or 1, the currently selected limit line is ON. If the value is set to OFF or 0, the currently selected limit line is OFF. The query version of the command returns a 1 if the currently selected limit line is ON and returns a 0 if OFF. Use :CALCulate:LIMit:TYPe to set the currently active limit line.

:CALCulate:MARKer:TABLe:DATA?
Title
Marker Table Data
Description
Reports marker information similar to the Marker table. The response begins with an ASCII header. The header specifies the number of following bytes. It looks like #AX, where A is the number of digits in X and X is the number of bytes that follow the header. Parameters are returned in comma-delimited ASCII format. Each parameter is returned as “NAME=VALUE[UNITS].”
Sets the location of the delta marker on the x-axis at the specified location <x-parameter> + the reference marker x-axis. <x-parameter> is defined in the current x-axis units. The query version of the command returns the location of the delta marker on the x-axis.
Parameter
<x-parameter>
Default Unit
Current x-axis unit
Example
If both the reference and delta marker #1 is currently at 1 GHz on the x-axis, send the command below to set the delta marker #1 to 2 GHz on the x-axis:
:CALCulate:MARKer1:DELTa:X 1GHz
(In zero span) If both the reference and delta marker #1 is currently at 25 us on the x-axis, send the command below to set the delta marker to 50us on the x-axis:
:CALCulate:MARKer1:DELTa:X 25us

Delta Marker Read Y Value
Description
Reads the current absolute Y value for the specified delta marker. The units are the units of the y-axis.
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 query version of the command returns the location of the marker on the x-axis. Note that the marker is snapped to the data point closest to the specified value. If the specified marker is not on it is set to on.
Parameter
<x-parameter>
Default Unit
Current x-axis unit
Example
To set reference marker #2 to 5 hertz on the x-axis:
:CALCulate:MARKer2:X 5 :CALCulate:MARKer2:X 5Hz
To set reference marker #1 to 1.5 GHz on the x-axis:
Sets math operations on the currently selected measurement and the trace stored in memory. Note that there MUST be a trace stored in Memory. Setting the FUNCtion to NORMal is equivalent of setting the Trace Math to “No Trace Math” on the front panel. Setting the FUNCtion to ADD is equivalent of setting the Trace Math to “Trace Plus Memory” on the front panel. Setting the FUNCtion to SUBTract is equivalent to setting the Trace Math to “Trace Minus Memory” on the front panel. The query version of the command returns the string “NORM” for no trace math, returns the string “ADD” for trace plus memory, and returns the string “SUBT” for trace minus memory.
Reports the maximum horizontal distance that can be analyzed in DTF. Note that the unit return is based on the current distance units.
