Channel Coupling
Set the coupling mode to filter out the undesired signals. For example, the signal
under test is a square waveform with DC offset.
 When the coupling mode is “DC”: the DC and AC components of the signal under
test can both pass the channel.
 When the coupling mode is “AC”: the DC components of the signal under test
are blocked. The waveform displayed always takes the zero voltage as the
center.
 When the coupling mode is “GND”: the DC and AC components of the signal
under test are both blocked.
Press CH1  Coupling and use to select the desired coupling mode (the
default is DC). The current coupling mode is displayed in the channel label at the
bottom of the screen. You can also press Coupling continuously to switch the
coupling mode.
DC AC GND
Bandwidth Limit
DS1000Z supports the bandwidth limit function. The bandwidth limit can reduce the
noise in the waveform displayed. For example, the signal under test is a pulse with
high frequency oscillation.
 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, the high frequency
components that exceed 20 MHz are attenuated.
Press CH1  BW Limit and use to enable or disable bandwidth limit (the
default is OFF). When bandwidth limit (20 MHz) is enabled, the character “B” will be
displayed in the channel label at the bottom of the screen. You can also press BW
