[SENSe:]VOLTage:AC:BANDwidth
Syntax [SENSe:]VOLTage:AC:BANDwidth {<filter>|MIN|MAX}[,(@<ch_list>)]
[SENSe:]VOLTage:AC:BANDwidth? [{(@<ch_list>)|MIN|MAX}]
Description
Set or query the AC filter parameter of the ACV measurements on the specified channels.
Parameters
Name
Type
Range
Default
<filter> Numeric
Any numeric value between MIN and
1000000. The final AC filter is decided by
the “
Principle of setting with samller
value
”.
The standard values of the range:
{3|20|200}
Wherein: MIN=3Hz, MAX=200Hz.
20Hz
<ch_list>
Channel
List
One or more channels (only for the
multiplexer channels), the rules are as
follows:
(@101): channel 01 on the module in
Slot1;
(@101:103): channel 01 through 03 on the
module in Slot;
(@101:103,301): channel 01 through 03
on the module in Slot1 and channel 01 on
the module in Slot3.
If the parameter is
omitted, this
command will be
applied to the
whole scan list.
Explanation  During the measurement, the filter type is determined by the frequency of the input
signal of the current channel as shown in the table below.
Input Frequency
AC Filter Type
3 Hz to 300 kHz
3 Hz (slow)
20 Hz to 300 kHz
20 Hz (medium)
200 Hz to 300 kHz
200 Hz (fast)
 The CONFigure:VOLTage:AC and MEASure:VOLTage:AC? commands automatically
select the 20 Hz filter.
 The instrument selects the 20 Hz filter automatically after a Factory Reset (send the
*RST command). An Instrument Preset (send the SYSTem:PRESet command) or Card
Reset (send the
SYSTem:CPON command) does not affect the current AC filter
parameter.
Return
Format
The query returns the AC filter parameter in scientific notation for each channel specified.
Multiple return values are separated by commas.
Example VOLT:AC:BAND 200,(@201,203)
VOLT:AC:BAND? (@201,203)
The query returns +2.000000000E+02, +2.000000000E+02.
