4-162 Agilent B1500A/B1505A Programming Guide, Edition 11
Command Reference
QSR
QSR
This command sets the current measurement range used for the quasi-static CV
measurement (MM13).
Syntax QSR range
Parameters range : Current measurement range. Integer expression. -9 to -14.
-9: 10 pA range fixed.
-10: 100 pA range fixed.
-11: 1 nA range fixed. Initial setting.
-12: 10 nA range fixed.
-13: 100 nA range fixed.
-14: 1 μA range fixed.
Remarks The range set by this command is used for both the leakage current measurement
and the capacitance measurement.
Use the QST command to set the integration time of the capacitance measurement
and the leakage current measurement.

QST
This command sets the integration time, hold time, and delay time of the quasi-static
CV measurement (MM13).
Syntax QST cinteg,linteg,hold,delay1[,delay2
]
Parameters cinteg : Integration time for the capacitance measurement, in seconds. Numeric
expression. The available values are 0.02 to 400 s for a 50 Hz line
frequency, and 0.016667 to 333.33 s for 60 Hz. But the value is
rounded as follows:
cinteg = n / selected line frequency (n : integer. 1 to 20000.)
The initial setting is 5/ selected line frequency. So this value is 0.1 s for
a 50 Hz line frequency, and approximately 0.083 s for 60 Hz.
