4- 88 Keysight B2961A/B2962A SCPI Command Reference, Edition 6
Subsystem Commands
SENSe Subsystem
The NPLC value can be expressed by the following formula, using the integration
time set by the
:SENSe:<CURRent[:DC]|VOLTage[:DC]>:APERture command. So
the last command setting is effective for both nplc and time.
nplc = time × power line frequency
Query response nplc <newline>
nplc returns the present setting of the number of power line cycles. If a parameter is
specified, nplc returns the value assigned to DEF, MIN, or MAX. Response data
type is NR3.
Example :SENS:CUR:NPLC 0.2
:SENS2:CURR:DC:NPLC?
:SENSe:<CURRent[:DC]|VOLTage[:DC]>:NPLCycles:
AUTO
Enables or disables the automatic NPLC function.
Syntax :SENSe[c]:<CURRent[:DC]|VOLTage[:DC]>:NPLCycles:AUTO mode
:SENSe[c]:<CURRent[:DC]|VOLTage[:DC]>:NPLCycles:AUTO?
For <CURRent[:DC]|VOLTage[:DC]>, set CURRent[:DC] for current measurement
or VOLTage[:DC] for voltage measurement. Specifying the measurement item is not
important because the mode value is common for all items.
Parameter mode 1|ON|0|OFF (default). Parameter data type is boolean.
mode=0 or OFF disables the automatic NPLC function.
mode=1 or ON enables the automatic NPLC function. If this function is enabled, the
instrument automatically sets the NPLC value (integration time) suitable for the
measurement range.
The automatic NPLC on/off works with the automatic aperture on/off set by the
:SENSe:<CURRent[:DC]|VOLTage[:DC]>:APERture:AUTO command. So the last
command setting is effective for both functions.
Query response mode <newline>
mode is 0 or 1, and indicates that the automatic NPLC function is off or on,
respectively. Response data type is NR1.
