How to Generate AM and FM Stimulus Signals for Functional Test

+ Expert Benchtop Waveform and Function Generator

Create Modulated Signals for Functional Validation

Amplitude modulation (AM) and frequency modulation (FM) provide realistic, repeatable stimulus signals for design verification and functional test. With a modern waveform and function generator, engineers can create AM and FM waveforms that exercise DUT behavior under controlled conditions, making it easier to observe how circuits respond to changing signal characteristics, operating scenarios, and expected input variations.

A dual-channel waveform and function generator produces modulated stimulus signals for analog, digital, and mixed-signal test environments, while complementary measurement instruments observe DUT response. This supports practical bench workflows for checking signal behavior, debugging design issues, evaluating circuit sensitivity, and confirming functional performance before progressing to more specialized validation, integration, and characterization stages

Functional Test Stimulus Solution

AM and FM stimulus signals help engineers evaluate DUT behavior under controlled modulation conditions during functional validation, debugging, response testing, and early-stage design verification. Using realistic, repeatable bench stimulus, engineers can exercise signal paths, observe circuit response, and assess performance across analog, digital, and mixed-signal designs. This approach is well suited for lab environments where flexible waveform generation is needed to simulate operating behavior, investigate design sensitivity, and confirm functional operation before progressing to more advanced characterization, integration, and system-level validation. Keysight Expert benchtop waveform and function generators support this workflow with versatile waveform generation for practical bench test setups.
