Digital Channel

DHO900 series oscilloscope provides a standard logic analyzer (LA) function with 16
digital channels. The default channel label is D0-D15. The oscilloscope compares the
voltages acquired in each sample with the preset logic threshold. If the voltage of the
sample point is above the threshold, it will be stored as logic 1; otherwise, it will be
stored as logic 0. The oscilloscope displays the logic levels (1s and 0s) in a graphic
way for you to easily detect and analyze the errors in circuit design (hardware design
and software design).
You can enter the LA menu in the following ways.
• Press the front-panel
• Click or tap the "LA" label at the bottom of the screen to enter the menu.
Before using the digital channels, connect the oscilloscope to the device under test
(DUT) using the optional PLA2216 active logic probe. To cater to different application
scenarios, PLA2216 provides two methods to connect the signal under test. For
