<value>
Zero-crossing position value, NR1 format, range from 2 to 10 without unit.
For example: WrtCmd( “COMP:PHAS:POS 3” ); the third zero-crossing point is used.
Query syntax: COMP:PHAS:POS？

comparator.
Command syntax: COMParator:PHASediff:DIFFerence <value>
Where,
<value> can be NR1, NR2 or NR3 format without unit.
For example: WrtCmd( “COMP:PHAS: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%.
