ST2515 Operation Manual
74
<Reference Resistance> = 0 to 110E+6 (NR3) the reference resistance of the
statistics function, unit: “Ω”
For example: WrtCmd(“STAT:REF 20E+3”); Set the reference resistance of the instrument statistics
function as 20kΩ.
NOTE: If the statistics function of the instrument is “ON”, ignore this command!
Query Syntax: STATistics: REFerence?
Return format: the format and unit of <Reference Resistance><NL^END> are the same as above.
The :STATistics:PERCent command sets the tolerance of the instrument statistics function.
The :STATistics:PERCent? query returns to the tolerance.
Command syntax:
STATistics:PERCent<Tolerance(%)>
Where,
<Tolerance(%)> = 0 to 99.999 (NR2) the tolerance of the statistics function,
unit: “%”
For example: WrtCmd(“STAT:PERC 10”); Set the tolerance of the instrument statistics function as
10%.
NOTE: If the statistics function of the instrument is “ON”, ignore this command!
Query Syntax: STATistics:PERCent?
Return format: the format and unit of <Tolerance(%)><NL^END> are the same as above.
The :STATistics:CLEAr command is used to clear the statistics results (all kinds of statistics).
NOTE: If the statistics function of the instrument is “ON”, ignore this command!
The :STATistics:NUMBer command is used to query the statistics numbers of statistics results.
Query Syntax: :STATistics:NUMBer?
Return format: <Total statistics numbers (NR1), valid statistics numbers (NR1)>
For example: WrtCmd(“:STAT:NUMB?”)
Returned value: 1256, 1243
The : STATistics:MEAN command is used to query the mean of the statistics results.
Query Syntax: :STATistics:MEAN?
Return format: <Mean (NR3)>
NOTE: When the valid statistics numbers >= 1, it will return the valid value or “+9.37”.
For example: WrtCmd(“:STAT:MEAN?”)
Returned value: 1.240E+01
The : STATistics:MAXimum command is used to query the maximum of the statistics results.
Query Syntax: :STATistics:MAXimum?
Return format: <Maximum (NR3), the corresponding data serial number of the maximum data
(NR1)>
