Bandwidth Limit
MSO1000Z/DS1000Z supports the bandwidth limit function which can reduce the
display noise. For example, the signal under test is a pulse with high frequency
oscillation.
 When the bandwidth limit is disabled, the high frequency components of the
signal under test can pass the channel.
 When limiting the bandwidth to 20 MHz, the high frequency components of the
signal under test that exceed 20 MHz are attenuated.
Press CH1, then press BW Limit continuously to switch the bandwidth limit state
(the default is OFF). When the bandwidth limit is enabled, the character "B" will be
displayed in the channel status label at the bottom of the screen.
Note: Bandwidth limit can reduce the noise as well as attenuate or eliminate the
high frequency components of the signal.
Probe Ratio
MSO1000Z/DS1000Z allows user to set the probe attenuation ratio manually. Press
CH1  Probe and use to select the desired probe ratio. The probe ratio values
available are as shown in the table below.
