ST2516 Series Operation Manual
51
Query Syntax: COMParator: LOWer?
Return format: the format and unit of < Lower threshold ><NL^END> are the same as above.
The :COMParator:REFerence command sets the reference resistance of the instrument
comparator function.
The :COMParator:REFerence? query returns to the current reference resistance.
Command syntax:
COMParator: REFerence<Reference Resistance>
Where,
< Reference Resistance > = 0 to 2.2E+6 (NR3) the reference resistance of the
comparator functio
n unit: ” Ω”
For example: WrtCmd(“COMP:REF 20E+3”); Set the reference resistance of the instrument
comparator fun
ction as 20kΩ.
Query Syntax: COMParator: REFerence?
Return format: the format and unit of < Reference Resistance ><NL^END> are the same as above.
The :COMParator:PERCent command sets the tolerance of the instrument comparator function.
The :COMParator:PERCent? query returns to the current tolerance.
Command syntax:
COMParator:PERCent<Tolerance(%)>
Where, < Tolerance(%) > = 0 to 99.999 (NR2) the tolerance of the comparator function
unit: ”%”
For example: WrtCmd(“COMP:PERC 10”); Set the tolerance of the instrument comparator
function as 10%.
Query Syntax: COMParator: PERCent?
Return format: the format and unit of < Tolerance(%) ><NL^END> are the same as above.
The :COMParator:RESult command querys the last comparator result of the instrument.
Query Syntax: COMParator: RESult?
Return format: < HI, IN, LO, OFF or ERR> <NL^END>
Where,
HI: it indicates that the measurement result is greater than the upper boundary of
the comparator
IN: it indicates that the measurement result is between the upper and lower
boundary of the comparator
LO: it indicates that the measurement result is less than the lower boundary of the
instrument
OFF: it indicates that the comparator function is “OFF”
ERR: it indicates that the comparator function is “ON”, but there exists the
measurement error.
