The :DIFFzone:RANGe command sets the comparison range of the Diffzone comparator. The :DIFFzone:RANGe?
query returns the current comparison range of the Diffzone comparator.
Command syntax: COMParator:DIFFzone:RANGe <start pot>, <end pot>
Where,
<start pot> start point of comparison range. NR1 format, range from 0 to 6000, without unit.
<end pot> end point of comparison range. NR1 format, range from 0 to 6000, without unit.
For example: WrtCmd(“COMP:DIFF:RANG 0,6000 ); set the comparison range from 0 to 6000.
NOTE: The
end point value should be larger than that of the start point; otherwise an error message will be displayed on
the system message line.
Query syntax: COMP:DIFF:RANG
？
Return format: <start pot>
，

start pot
，
end pot are NR1 format.
The :DIFFzone:DIFFerence command sets the difference limit value of Diffzone comparator.
The :DIFFzone:DIFFerence? query returns the current difference limit value of the Diffzone comparator.
Command syntax: COMParator:DIFFzone:DIFFerence <value>
Where,
<value> can be NR1, NR2 or NR3 format without unit.
For example: WrtCmd( “COMP:AREA:DIFF 2.5” ); set the difference limit value to 2.5%.
NOTE: Here <value> is a percent value, for example, input 2.5 for 2.5%.
Query syntax: COMParator:DIFFzone:DIFFerence
？
Return format: <NR2><NL^END>
