Where,
<value>
Zero-crossing position value, NR1 format, range from 1 to 99 without unit.
For example: WrtCmd( “COMP:PHAS:POSI 3” ); the third zero-crossing point is used.
Query syntax: COMP:PHAS:POSI
？
Return format: <NR1><NL^END>
The :PHASediff:DIFFerence command sets the difference limit value of the Phasediff comparator.
The :PHASediff:DIFFerence? query returns the current difference limit value of the Phasediff 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%.
Query syntax: COMParator:PHASediff:DIFFerence
？
Return format: <NR2><NL^END>
8.4.4 Impulse VOLTage subsystem commands
The Impulse VOLTage subsystem commands set the impulse voltage, average times, impulse voltage auto adjust
and delay, etc. Figure 8-6 shows the Impulse VOLTage subsystem command tree.

Figure 8-6 Impulse VOLTage subsystem command tree
The [:VOLTage] command sets the impulse voltage for testing. The [:VOLTage]? query returns the current impulse
voltage value.
Command
syntax:
<value>
IVOLTage[:VOLTage] MIN
MAX
Where,
<value> can be NR1, NR2 or NR3 format followed by KV or V and the value must be between100V to 5000V.
MIN
Set the impulse voltage to 100V.
MAX Set the impulse voltage to 5000V.
For example: WrtCmd( “IVOLT:VOLT 1000V” ); set the impulse voltage to 1000V.
Query syntax: IVOLTtage:[VOLTage]
？
Return format: <NR1><NL^END>
NOTE: The query returns no unit, and the default voltage unit is V.
