Digital Channel
This series oscilloscope provides the standard the logic analyzer (LA) function, and it
has 16 digital channels. The default channel label is D15-D0. The oscilloscope
compares the voltages acquired in each sample with the preset logic threshold. If the
voltage of the sample point is greater than the threshold, it will be stored as logic 1;
otherwise, it will be stored as logic 0. The oscilloscope displays logic levels ("1" and
"0") in the form of a graph for you to easily detect and analyze the errors in circuit
design (hardware design and software design).
Before using the digital channels, connect the oscilloscope and the device under test
using RPL2316 logic probe provided in the accessories. To apply to different
application scenarios, RPL2316 provides three connection methods to connect the
signal under test. For details, refer to RPL2316 Logic Probe User Guide.
NOTE
The digital channel input terminal does not support hot plugging. Please do not insert or pull
out the logic probe when the instrument is in power-on state.

To Select the Digital Channel
Press
the bottom of the screen to enter LA setting menu. Press Select to open the channel
menu, and rotate the multifunction knob
Select continuously or enable the touch screen to select it.
•
Select any of the digital channels (D0-D15). The channel label and waveform of
the selected channel are displayed in red.
•
Select the user-defined group: selects any group of the channels from the four
user-defined groups. The labels and the waveforms of all the channels in the
selected channel group will be indicated in red.
NOTE
Only the enabled digital channel can be selected, and only the user-defined channel group
that has been grouped can be available.
