This white paper discusses the importance of stress testing and explains how to use a function generator to simulate the waveform and stress test your device.
FUNCTION GENERATOR USE FULL
Engineers must test the limits of their designs to ensure that the products achieve ideal maximum performance and the new hardware meets design specifications across the full range of operations. Identifying the potential breaking points in your application will allow you to correct them before they become expensive production issues. Stress testing provides valuable insight into the performance of your device under extreme load. Therefore, engineers need to stress their devices with these kinds of distortions during design, validation, and production. The design must minimize distortions to ensure accurate and reliable operation. Transient signal spikes can appear to be valid clocks, or the receiving system might misinterpret data. Noise, jitter, cross talk, and reflections can cause signal distortions. If they do not, the result could be communication errors or system failures. Some function generators allow you to perform advanced modulation to add noise, random jitter, or deterministic jitter to the signal.Digital components and circuits must be able to withstand a certain amount of noise and jitter in clock and data signals to ensure the reliable operation of your device. You can even perform skew adjust to shift either the I or Q baseband signal in time with picoseconds of resolution. You can simulate nonideal IQ signals by adjusting the gain balance between the two channels and the amplitude offset for each channel.
Therefore, they must generate a high-quality, known-good signal. To do this, they must first generate an ideal signal to test the design’s ideal performance. Testing with simulated IQ signals is critical because designers face a continual bandwidth crunch in a spectrum filled with interference.įor example, designers need to test their designs’ limits to ensure real-world performance. It is popular because of its efficient use of bandwidth, which continues to be a challenge in our data-hungry world. In-phase quadrature modulation, or IQ modulation, is the dominant modulation scheme in communication applications. Trueform never skips points and is always anti-aliased. Play your signals as defined, at your exact sample rate, without missing short-duration anomalies that are critical for testing device reliability. You’ll see your design’s characteristics, not the waveform generator’s, in your measurements.ĭefine any waveform shape and length using the Trueform arbitrary waveform capability. Clean, spurious-free signals don’t introduce noise or artifacts. With a total harmonic distortion of just 0.03%, Trueform waveform generators offer up to 5x better fidelity than other generators. With better jitter performance, you can place edges more accurately, helping reduce timing errors in your circuit design. You can even use them as a system clock for timing and triggering other instruments. With jitter as low as 1 ps, Trueform function / arbitrary waveform generators offer exceptional edge stability. What is the advantage of Trueform technology?
