Bandwidth Limit
Set the bandwidth limit to reduce display noise. For example, the signal under test is
a pulse with high frequency oscillations.
 When bandwidth limit is disabled, the high frequency components of the signal
under test can pass the channel.
 Enable bandwidth limit and limit the bandwidth to 20 MHz, 100 MHz or 200 MHz,
the high frequency components that exceed 20 MHz, 100 MHz or 200 MHz are
attenuated.
Press CH1  BW Limit and use to enable or disable the bandwidth limit (the
default is OFF). When the bandwidth limit (20 MHz, 100 MHz or 200 MHz) is enabled,
the character “B” will be displayed in the channel label at the bottom of the screen.
You can also press BW Limit continuously to switch between on and off of the
bandwidth limit.
