Lessons
Lesson 1 - Spectrum Analyzer vs. Signal Analyzer Measurements

Lesson 1 - Spectrum Analyzer vs. Signal Analyzer Measurements

Explore the types of measurements you can perform including frequency, amplitude, width, phase, and spurious emissions. Understand the capabilities and limitations of different analyzers and how to choose the right one for your task.

Lesson 2 - Time Domain vs. Frequency Domain

Lesson 2 - Time Domain vs. Frequency Domain

Learn how the same signal appears from the time and frequency domain perspectives. The time domain represents a signal’s time variation, while the frequency domain represents the signal’s frequency components. You’ll also discover how the Fourier transform bridges the gap between these two perspectives.

Lesson 3 - Understanding Spectrum and Spurious Emissions

Lesson 3 - Understanding Spectrum and Spurious Emissions

Spectrum is the distribution of signal power across a range of frequencies, while spurious emissions are unwanted signals present in a signal's spectrum. Spectrum analyzers are used to measure spectrum and spurious emissions, helping you detect interference that can affect system performance.

Lesson 4 - Boosting Dynamic Range to See Low Level Signals

Lesson 4 - Boosting Dynamic Range to See Low Level Signals

Dynamic range is the difference between the smallest and largest signals that can be measured by a spectrum analyzer. Learn how to increase the dynamic range by averaging or attenuating the input signal and using a narrow bandwidth.

Lesson 5 - What is Noise Figure and How Do You Measure It?

Lesson 5 - What is Noise Figure and How Do You Measure It?

Noise figure is critical when you’re trying to detect weak signals buried in the noise floor. This lesson explains what it means, why it matters, and how to measure it effectively with a signal analyzer.
