[SENSe:]{RESistance|FRESistance}:APERture {<
seconds
>|MIN|MAX|DEF}
[SENSe:]{RESistance|FRESistance}:APERture? [{MIN|MAX|DEF}]
Specifies the integration time in seconds (called
aperture time
) for resistance measurements.
Use this command for precise control of the DMM's integration time. Use NPLC (see
) for better power-line noise rejection characteristics (NPLC
> 1)..
This parameter is common to 2-wire and 4-wire resistance measurements. Using the
FRESistance version of this command or query is identical to using the RESistance ver-
sion.
Parameter
Typical Return
(
Without
the DIG option) 200 µs to 1 s (2 µs resolution), default: 100 ms. (
With
the DIG
option) 20 µs to 1 s (2 µs resolution), default: 100 ms.

Enable aperture, set aperture time to 300 milliseconds:
RES:APER:ENAB ON
RES:APER 300E-03
or
FRES:APER:ENAB ON
FRES:APER 300E-03
l
Applies only to the 34465A and 34470A.
l
Affects both 2-wire and 4-wire resistance measurements.
l
Both the [SENSe:]<
function
>:NPLC and [SENSe:]<
function
>:APERture commands control the instru-
ment's integration time. When using both commands (not recommended), whichever command is
sent last will override the other command and set the integration time. Sending the
[SENSe:]<
function
>:APERture command sets the [SENSe:]<
function
>:APERture:ENABled command
to 1 (ON); sending [SENSe:]<
function
>:NPLC sets it to 0 (OFF).
l
This parameter is set to its default value after a Factory Reset (
) or Instrument Preset
(
).
