What does a spectrum analyzer display?

What do spectrum analyzers measure? A spectrum analyzer displays a spectrum of signal amplitudes on different frequencies. It enables analysis that determines whether signals fall within required limits. It displays spurious signals, complex waveforms, rare short-duration events and noise.

What is a real time spectrum analyzer?

The Real-Time Spectrum Analyzer performs signal analysis using real-time digital signal processing (DSP) that is done prior to memory storage. Real time processing allows the user to discover events that are invisible to other architectures and to trigger on those events allowing their selective capture into memory.

How do you protect a spectrum analyzer?

Now, it is a lesson learnt that one should always consider protecting the RF input of a spectrum analyser when measuring unknown signals. The best way of doing so is prior to the measurement, use a transient limiter and/or a high pass filter (9kHz).

How accurate is a spectrum analyzer?

Modern analyzers can measure frequencies with an accuracy of < 0.1%, which is ideal for wireless communication applications.
