To Enable The Analog Channel; Channel Coupling - Rigol DS1000Z-E Series User Manual

RIGOL

To Enable the Analog Channel

DS1000Z-E provides 2 analog input channels (CH1 and CH2). As the setting methods
of the vertical systems of the two channels are the same, this chapter takes CH1 as
an example to illustrate the setting method of the vertical system.
Connect a signal to the channel connector of CH1 and then press CH1 in the vertical
control area (VERTICAL) on the front panel to enable CH1. At this point, the channel
setting menu is displayed at the right side of the screen and the channel status label
at the bottom of the screen (as shown in the figure below) is highlighted. The
information displayed in the channel status label is related to the current channel
setting.
After the channel is turned on, modify the parameters such as the vertical scale,
horizontal time base, trigger mode and trigger level according to the input signal for
easy observation and measurement of the waveform.

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.
When the coupling mode is "GND": the DC and AC components of the signal

under test are both blocked.
Press CH1  Coupling and use
default 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 press Coupling
continuously to switch the coupling mode.
