[SENSe:]VOLTage:AC:BANDwidth {<filter>|MIN|MAX|DEF}
[SENSe:]VOLTage:AC:BANDwidth? [{MIN|MAX|DEF}]
Sets the bandwidth for AC voltage measurements.
The instrument uses three different AC filters that enable you either to optimize low frequency accuracy or
to achieve faster AC settling times following a change in input signal amplitude. The instrument selects the
slow (3 Hz), medium (20 Hz) or fast (200 Hz) filter based on the cutoff frequency specified by this com-
mand. Specify the lowest frequency that you expect to encounter.
Parameter Typical Return
{3 Hz|20 Hz|200 Hz}. Default: 20Hz. +2.00000000E+01
Make and read an AC voltage measurement. Use the 3 Hz filter bandwidth:

l If you enter the lowest expected frequency that you intend to encounter, the command will select the
appropriate <filter>. For example, if you enter 15 Hz, the slow filter (3 Hz) is selected. If you enter 190
Hz, the medium filter (20 Hz) is selected to provide the appropriate low cutoff.
l Set the lowest frequency that you expect to encounter. Lower bandwidths result in longer settling
delays, as shown:
Input Frequency Default Settling Delay
3 Hz - 300 kHz (Slow) 2.5000 s/measurement
20 Hz - 300 kHz (Medium) 0.6250 s/measurement
200 Hz - 300 kHz (Fast) 0.0250 s/measurement
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset
(SYSTem:PRESet).
