14 Mixed signal option (MSO, R&S MXO4-B1)
The Mixed Signal Option R&S MXO4-B1 adds logic analyzer functions to the classical
oscilloscope functions. Using the MSO option, you can analyze and debug embedded
systems with mixed-signal designs that use analog signals and correlated digital sig-
nals simultaneously.
The Mixed Signal Option provides 16 digital channels grouped in two logic probes
(pods) with 8 channels each. The instrument ensures that analog and digital wave-
forms are time-aligned and synchronized so that critical timing interactions between
analog and digital signals can be displayed and tested. The automatic alignment com-
pensates the skew between the probe connectors of the analog channels and the
probe boxes of the digital channels.
14.1 Logic configuration
Access: "Menu" > "Logic" > "Setup" tab
You can display digital channels individually, and you can group them and display as a
logic group. 4 logic groups are available. Each digital channel can be assigned to one
active logic only, and the instrument disables conflicting buses automatically.
For clocked buses, you can display the decoded data in a result box.
If you have configured several logic groups and you want to modify the settings, make
sure that the tab of the correct logic is selected. Disable the logic before you change
the settings.
