[SENSe:]CURRent:AC:BANDwidth
Syntax [SENSe:]CURRent:AC:BANDwidth {<filter>|MIN|MAX}[,(@<ch_list>)]
[SENSe:]CURRent:AC:BANDwidth? [{(@<ch_list>)|MIN|MAX}]
Description
Set or query the AC filter parameter of the ACI measurements on the specified channels.
Parameters
Name
Type
Range
Default
<filter> Numeric
Any numeric value between MIN and
1000000. The final AC filter parameter 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 channel 21
to channel 24 of MC3324), the rules are as
follows:
(@121): channel 21 on the module in Slot1;
(@121:123): channel 21 through 23 on the
module in Slot1;
(@121:123,324): channel 21 through 23 on
the module in Slot1 and channel 24 on the
module in Slot3.
If the parameter
is omitted, this
command will be
applied to the
whole scan list.
Explanation  The CONFigure:CURRent:AC and MEASure:CURR:AC? command automatically select
the 20 Hz filter.
 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 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 CURR:AC:BAND? (@121,122)
The query returns 2.000000000E+01,3.000000000E+00.
