Logic analyzer (option R&S
RTA-B1, MSO)
The Mixed Signal Option R&S
RTA- B1 adds logic analyzer functions to the classical
oscilloscope functions. Using the logic analyzer, you can analyze and debug embed-
ded systems with mixed-signal designs that use analog signals and time-correlated
digital signals simultaneously. The option provides 16 logic channels grouped in two
logic probes (pods) with 8 channels each. The instrument ensures that analog and digi-
tal waveforms are time-aligned and synchronized so that critical timing interactions
between analog and digital signals can be displayed and tested.
Ensuring accurate measurement results
The logic analyzer option R&S
RTA-B1 with connected probe leads is considered as a
test probe, according to EN 61326-2-1, clause 5.2.4.101. Therefore, the measure-
ments are sensitive to electromagnetic interference. Consider additional shielding
methods to avoid interference.
Consider the following guidelines for good probing practices:
●
Attach the ground lead from each pod to the ground of the device under test if any
logic channel of the pod is used for data capture. The ground lead improves signal
fidelity to the oscilloscope, ensuring accurate measurements.
●
For high-speed timing measurements (rise time < 3 ns), use an own ground for
each pod.
To activate logic analysis
► Press the [Logic] key.

Short menu for logic channels
There are two short menus that show the status of the logic channels, one for the pod
"D7...D0" and one for the pod "D15...D8".
► To open the short menu for logic channels, tap the pod label in the bottom line of
the display.
If the pod was not selected, tap twice: once to select the pod, and next to open the
short menu.
