Can I use a VNA as a spectrum analyzer?
In some cases, a VNA receiver can be used for the purposes of simplified spectrum analysis, which might include detection of self-excitation, determination of signal power and harmonic level, or spectrum deviation from an expected reference spectrum, among other parameters.
What is frequency span in spectrum analyzer?
Center frequency and span
Span specifies the range between the start and stop frequencies. These two parameters allow for adjustment of the display within the frequency range of the instrument to enhance visibility of the spectrum measured.
How do you describe the frequency of a spectrum?
The frequency spectrum of an electrical signal is the distribution of the amplitudes and phases of each frequency component against frequency. The use of higher frequencies is desirable because of the smaller antenna size, the improved directional effect of the antennae, and the broader available frequency spectrum.
