How to Debug Devices with Mixed-Signal Inputs

+ Pulse Generator

Debug Mixed-Signal Device Behavior

Mixed-signal device debug becomes difficult when analog stimulus, digital transitions, modulation behavior, and timing conditions come from separate or inconsistent sources. Small changes in waveform shape, trigger behavior, voltage levels, or edge timing can hide whether a failure is caused by the input stimulus or the device under test.

To debug these devices more consistently, engineers can replace variable upstream sources with controlled pulse, function, arbitrary, pattern, noise, or jittered waveform stimulus at the device input. This allows adjustments to timing, levels, waveform shape, and modulation behavior while engineers monitor the device response with an oscilloscope, analyzer, counter, or system measurement path.

Mixed-Signal Input Debug Solution

Mixed-signal input debug requires separating device behavior from inconsistent or difficult-to-control stimulus sources. A Keysight pulse generator provides pulse, pattern, function, arbitrary waveform, noise, jitter, and timing stimulus for exercising mixed-signal device inputs. Engineers can configure waveform type, voltage levels, pulse parameters, trigger behavior, and stressed or nominal input conditions while observing downstream response. The setup supports functional debug when the device must be tested with repeatable stimulus instead of a variable upstream circuit or separate signal sources.
