:CHANnel<n> Commands
The :CHANnel<n> commands are used to set or query the vertical system parameters of the analog
channels, such as the bandwidth limit, coupling, vertical scale, and vertical offset.

Syntax :CHANnel<n>:BWLimit <type>

Discrete
{20M|OFF}
OFF
Explanation  OFF: disable the bandwidth limit and the high frequency components of the signal
under test can pass the channel.
20M: enable the bandwidth limit and the high frequency components of the signal
under test that exceed 20 MHz are attenuated.
 Enabling the bandwidth limit can reduce the noise, but can also attenuate the high
frequency components.
Return
Format
The query returns 20M or OFF.
Example
:CHANnel1:BWLimit 20M /*Enable the 20MHz bandwidth limit*/
:CHANnel1:BWLimit? /*The query returns 20M*/
