Subsystem Commands

:SENSe:<CURRent[:DC]|RESistance|VOLTage[:DC]>:APERture

SENSe Subsystem

For the numeric suffix [c], see “Numeric Suffix” on page 1-8.

:SENSe:<CURRent[:DC]|RESistance|VOLTage[:DC]>:

APERture

Sets the integration time for one point measurement.

Syntax :SENSe[c]:<CURRent[:DC]|RESistance|VOLTage[:DC]>:APERture time

:SENSe[c]:<CURRent[:DC]|RESistance|VOLTage[:DC]>:APERture? [time]

For <CURRent[:DC]|RESistance|VOLTage[:DC]>, set CURRent[:DC],

RESistance, or VOLTage[:DC]. Specifying the measurement item is not important

because the time value is common for all items.

Parameter time value (+8E-6 to +2 seconds)|MINimum|MAXimum|DEFault

(default is 0.1 PLC, =0.1/power line frequency). Parameter data

type is NRf+. Query does not support time=value. If you

specify the value less than MIN or greater than MAX, time is

automatically set to MIN or MAX.

The integration time can be expressed by the following formula, using the NPLC

value set by the

:SENSe:<CURRent[:DC]|RESistance|VOLTage[:DC]>:NPLCycles

command. So the last command setting is effective for both time and nplc.

time = nplc / power line frequency

Query response time <newline>

time returns the present setting of the integration time. If a parameter is specified,

time returns the value assigned to DEF, MIN, or MAX. Response data type is NR3.

Example :SENS:CUR:APER 2E-3

:SENS2:CURR:DC:APER?

:SENSe:<CURRent[:DC]|RESistance|VOLTage[:DC]>:

APERture:AUTO

Enables or disables the automatic aperture function.
