BANDWIDTH_LIMIT, BWL
Command /Query
DESCRIPTION
BANDWIDTH_LIMIT enables or disables the
bandwidth-limiting low-pass filter. If the
bandwidth filters are on, it will limit the
bandwidth to reduce display noise. When you
turn Bandwidth Limit ON, the Bandwidth
Limit value is set to 20 MHz. It also filters the
signal to reduce noise and other unwanted
high frequency components.
The response to the BANDWIDTH_LIMIT?
Query indicates whether the bandwidth filters
are on or off.
