Chapter 7 Logic Analyzer
MSO4000 series mixed signal digital oscilloscope provides the logic analyzer (LA)
function. The logic analyzer consists of 16 logic channels (namely, digital channels;
the default channel labels are D15 to D0). The oscilloscope compares the voltage
values obtained in each sample of the digital channel with the preset logic threshold.
If the voltage of the sample point is greater than the threshold, it is stored as logic
“1” (logic high level); otherwise, it is stored as logic “0” (logic low level). The
ocilloscope displays the logic level values (“1” and “0”) of the waveform points in
graph mode for users to easily test and analyze the errors in the circuit design
(hardware design and software design).
Before using the digital channels, connect the oscilloscope and device under test
using the RPL2316 logic probe provided in the accessories. For the using method of
the logic probe, please refer to the
RPL2316 Logic Probe User’s Guide
.
