[SENSe:]VOLTage:AC:BANDwidth {<freq> | MIN | MAX | DEF} [, (@<ch_list>)]
[SENSe:]VOLTage:AC:BANDwidth? [{(@<ch_list>) | MIN | MAX | DEF}]
Sets the bandwidth for AC voltage measurements.
The instrument uses three different ACfilters that enable you to either optimize low frequency accuracy or achieve
faster AC settling times following a change in input signal amplitude.
Parameter Typical return
{3 Hz|20 Hz|200 Hz}. Default: 20 Hz. +2.00000000E+01
Configure an AC voltage measurement. Use the 3 Hz filter bandwidth:
CONF:VOLT:AC 1
VOLT:AC:BAND 3
–
For the <freq> parameter, specify 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) 1.66 s/measurement
20 Hz - 300 kHz (Medium) 0.25 s/measurement
200 Hz - 300 kHz (Fast) 0.025 s/measurement
– This parameter is set to its default value after a Factory Reset (*RST command).
– The settling delay is controlled by ROUTe:CHANnel:DELay command. You can get the default delay with
ROUTe:CHANnel:DELay:AUTO ON command.
