What is a spectrum analyzer? The spectrum analyzer is connected to the system we want to examine and displays the signals passing through this system on the device screen without interfering with the signals in any way. These devices can be defined as a “passive receiver.”
It is the most commonly used testing device in activities related to communications, whether in production, design, or fieldwork. The answer to the question “What is a spectrum analyzer?” in short is: a testing device for communication systems.
With our testing device, the spectrum analyzer, we can obtain information about the system’s performance by analyzing electrical signals. Thus, we can identify the source of the problem and take steps to resolve it.
Details about using the device
The screen of the spectrum analyzer, which has a special structure, is divided into grids. Depending on the option chosen by the user, these grids can represent:
- Frequency range
- Voltage value
- Span
- Time
Spectrum analyzers are not only used for satellite communications. Depending on the device used, you need to know the characteristics of the relevant equipment’s signal.
For example, if you work with satellite communication equipment, the generated signal is high frequency and modulated. You need to work knowing this. In other systems, unmodulated and low-frequency signals may be used.
Aspects to be considered
If you plan to purchase a spectrum analyzer for testing your systems, the most important aspect to pay attention to is the frequency range. For example, for IF-L band systems it should be 2GHz.
Another important point related to this device is the type of input voltage. Do not apply DC voltage to the analyzer input. If applied, the device may be damaged. If the system to which you connect the device contains DC voltage, we recommend the mandatory use of a DC Block.
