[SENSe:]TEMPerature:APERture {<seconds>|MIN|MAX|DEF}
[SENSe:]TEMPerature:APERture? [{MIN|MAX|DEF}]
Specifies the integration time in seconds (called aperture time) for temperature measurements.
Use this command for precise control of the DMM's integration time. Use NPLC (see
[SENSe:]TEMPerature:NPLC) for better power-line noise rejection characteristics
(NPLC > 1).
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.
+1.00000000E-
01
Enable aperture, set the aperture time to 300ms:
TEMP:APER:ENAB ON
TEMP:APER 300E-03
l Applies only to the 34465A and 34470A.

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 (*RST) or Instrument Preset
(SYSTem:PRESet).
[SENSe:]TEMPerature:APERture:ENABled {ON|1|OFF|0}
[SENSe:]TEMPerature:APERture:ENABled?
Enables the setting of integration time in seconds (called aperture time) for temperature measurements.
If aperture time mode is disabled (default), the integration time is set in PLC (power-line cycles).
Parameter Typical Return
{ON|1|OFF|0}. Default: OFF. 0(OFF)or1(ON)
Enable aperture time mode, set the aperture time to 300ms:
TEMP:APER:ENAB ON
TEMP:APER 300E-03
l Applies only to the 34465A and 34470A.
l The CONFigure:TEMPerature, MEASure:TEMPerature?,and [SENSe:]TEMPerature:NPLC commands
disable the aperture time mode, and select an integration time in number of power line cycles.
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset
(SYSTem:PRESet).
