Features and Functions 2
• 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 Keysight 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 Temp). 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.
