52 34410A/11A/L4411A User’s Guide
2Features and Functions
• Remote Interface Operation: The following commands set the integration time
in NPLC:
[SENSe:]VOLTage[:DC]:NPLC {<
PLCs >>MIN>MAX>DEF}
[SENSe:]CURRent[:DC]:NPLC {<
PLCs >>MIN>MAX>DEF}
[SENSe:]RESistance:NPLC {<
PLCs >>MIN>MAX>DEF}
[SENSe:]FRESistance:NPLC {<
PLCs >>MIN>MAX>DEF}
[SENSe:]TEMPerature:NPLC {<
PLCs >>MIN>MAX>DEF}
Each of these commands also has a query form.
Refer to the Agilent 34410A/11A/L4411A Programmer’s Reference Help for
a complete description and syntax for these commands.
Aperture mode. Aperture is the period, measured in seconds, during which
the multimeter’s analog–to–digital (A/D) converter samples the input signal
for a measurement. A longer aperture yields better resolution; a shorter
aperture provides for faster measurements. This mode allows the user to set a
specific integration time, not based on power–line frequency. Values range
from 100 μs to 1 second for the 34410A, and from 20 μs to 1 second for the
34411A/L4411A.
• To allow for normal mode (line frequency noise) rejection, select the NPLC
option for INTEGRATION, with an integral number of NPLCs. Use the APERTURE
method only if you need precise control over the multimeter’s integration
time, in seconds.
• Front Panel Operation: Select a dc measurement function (DC V, DC I, Ω 2W,
Ω 4W or Te m p ). Press as required:
...
> INTEGRATION > APERTURE
Use the navigation keypad to set the desired aperture value, and press .
Then step through or exit the configuration menu.
• Remote Interface Operation: The following commands set the aperture value,
in seconds:
[SENSe:]VOLTage[:DC]:APERture {<
seconds >>MIN>MAX>DEF}
[SENSe:]CURRent[:DC]:APERture {<
seconds >>MIN>MAX>DEF}
[SENSe:]RESistance:APERture {<
seconds >>MIN>MAX>DEF}
[SENSe:]FRESistance:APERture {<
seconds >>MIN>MAX>DEF}
[SENSe:]TEMPerature:APERture {<
seconds >>MIN>MAX>DEF}
Each of these commands also has a query form.
