Stress testing designs under real-world conditions with a two-tone signal

Testing design limits requires simulating a signal with quantitative, nonideal characteristics using a high-quality, known-good signal source. To characterize design limits and measure the quality of signal timing, designers must add distortion waveforms, jitter, or noise to stress test their devices under non-ideal conditions. Using a waveform generator, design engineers begin with an ideal signal, then stress test the design by adding noise to one test channel using a two-tone signal.

The waveform generator produces low-distortion, stable, reliable signals and utilizes summing capabilities to generate an intentionally non-ideal waveform for device testing. This process checks the device under test’s (DUT's) robustness and immunity under simulated non-ideal, real-world operational conditions.

Two-tone signal generation solution

Stress testing telecommunication components requires stimulating the design with non-ideal signals that include two-tone noise.  The Keysight two-tone signal generation solution consists of a waveform generator that generates user-defined waveforms point-by-point to meet the target shape and length. Keysight sources have high accuracy and very low jitter, enabling you to place edges more accurately and reduce timing errors. At the same time, the sum function enables you to add an internal or external generated signal to the primary signal. You can easily adjust each dual tone's amplitude, frequency, and duration to the limits specified in the regulatory standard.
