{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 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*/
