2Features and Functions
AC Measurements
AC Filter
Applies to ac voltage, ac current, frequency, and period measurements only.
The multimeter provides three bandwidth (ac signal filter) selections. Set the
bandwidth for the lowest frequency you expect to encounter. Note that a lower
bandwidth setting results in longer settling times, as shown in the table below.
• Front Panel Operation: Select the ac voltage, ac current, frequency, or period
function. Press as required.
...
> AC FILTER
Select 3 HZ: SLOW, 20 HZ: MEDIUM, or 200 HZ: FAST, and then step through or
exit the menu.
• Remote Interface Operation: The following commands set the ac filter (3, 20 or
200 Hz) for ac measurements:
[SENSe:]VOLTage:AC:BANDwidth {<
filter
>>MIN>MAX>DEF}
[SENSe:]CURRent:AC:BANDwidth {<
filter
>>MIN>MAX>DEF}
The following commands query the filter setting:
[SENSe:]VOLTage:AC:BANDwidth? [{MIN>MAX}]
[SENSe:]CURRent:AC:BANDwidth? [{MIN>MAX}]
Refer to the Agilent 34410A/11A/L4411A Programmer’s Reference Help for
a complete description and syntax for these commands.
