Spectrum analyzer specifications: Things you need to know!
Spectrum analyzer is used for a variety of purposes, such as RF testing, verification, development, base service and repair, validation testing, installation, production, and service. There are various types of spectrum analyzers, including 2.5GHz spectrum analyzer, 3GHz Spectrum Analyzer, 6GHz Spectrum Analyzer and more. According to your needs, you can choose the most suitable option for yourself.
Do you know in order to use the right spectrum analyzer, you must be familiar with its specifications? With the knowledge of its specifications, you can choose the right analyzer and get yourself familiar with its limitations.
Although the specifications of a spectrum analyzer is a bit complicated, at least a basic understanding is crucial when buying these instruments.
Spectrum analyzers are expensive. Therefore, you must invest wisely. To understand more about spectrum analyzer specifications, read below.
Frequency coverage - Frequency coverage is one of the most important specifications for a spectrum analyzer. When it comes to a spectrum analyzer, it can measure frequency from zero Hertz to its highest frequency level.
Frequency accuracy specification - Another important specification for the spectrum analyzer is frequency accuracy. Usually, the frequency accuracy is treated differently for older and newer analyzers.
Amplitude accuracy - Amplitude accuracy specification for a spectrum analyzer is also essential for the measurements that are read by the test instrument. Here are the two most important specifications associated with amplitude accuracy.
- Relative accuracy specifications
- Absolute accuracy specifications
Resolution bandwidth - We cannot miss out on resolution bandwidth when talking about spectrum analyzer specification, especially when it comes to measuring close signals. The best way to determine the resolution bandwidth is through the bandwidth of the analyzer’s filter. However, you should also consider other factors, such as residual FM, filter type and noise sidebands when determining the resolution bandwidth.
The bottom line
With these specifications, you can understand the difference between superheterodyne spectrum analyzers and FFT spectrum analyzers. Also, you get to know spectrum analyzer limitations. This will help you make the right decision when choosing the right spectrum analyzer. Depending on your needs, you can either choose GHz Spectrum Analyzer or 6GHz Spectrum Analyzer.
