FAQ

A Spectrum Analyzer is an electronic test instrument that measures and displays signal amplitude as a function of frequency. It is used to analyze RF signals, identify interference, measure harmonics, and verify signal quality in electronic and communication systems.

Spectrum Analyzers are widely used in:

  • RF and wireless communication testing

  • Electronics design and troubleshooting

  • EMC / EMI compliance testing

  • Signal integrity analysis

  • Antenna and transmitter evaluation
    They are essential tools in laboratories, manufacturing, and R&D environments.

A Spectrum Analyzer displays signals in the frequency domain, showing how signal power is distributed across frequencies. An Oscilloscope displays signals in the time domain, making it better suited for observing waveforms, timing, and transient behavior.

Key specifications include:

  • Frequency range

  • Resolution bandwidth (RBW)

  • Dynamic range

  • Phase noise

  • Sensitivity and accuracy
    The right specifications depend on whether the application involves RF design, EMI testing, or general electronics troubleshooting.

Yes. Spectrum Analyzers are commonly used for pre-compliance EMC and EMI testing to detect unwanted emissions and interference.
When combined with the appropriate accessories and dedicated EMC test equipment, they help engineers identify and resolve issues early—before formal compliance testing.
In addition, we offer access to a professional EMC testing chamber at 3 QLABS, enabling controlled, reliable measurements and faster development cycles.
