right side of the Offset input field to decrease or increase the offset. You can
also tap the Offset input field to input a specific value with the displayed
numeric keypad.
Channel Coupling
The undesired signals can be filtered out by setting the coupling mode. 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.
Press
1 to open the setting menu of CH1. Then, press Coupling continuously or
rotate the multifunction knob to select the desired coupling mode (by default, it
is DC). The current coupling mode is displayed in the channel status label at the
bottom of the screen, as shown in the figure below. You can also enable the touch
screen, and then touch the CH1 setting menu to select the desired coupling mode.

Bandwidth Limit
MSO5000 series supports the bandwidth limit function. Setting the bandwidth limit
can reduce the noises in the displayed waveforms. 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 you enable the bandwidth limit and limit it to 20 MHz, 100 MHz, or 200
MHz, the high frequency components found in the signal under test that are
greater than 20 MHz, 100 MHz, or 200 MHz are attenuated.
