A Guide To Dual or Triple Spectrum Analyzers

A spectrum analyzer is an electronic device used to analyze a wide variety of the frequency spectrum of RF, Audio signals, and radio frequency. Moreover, they are used in many other fields such as- industries, labs, and military applications. There are many types of spectrum analyzers having different frequency measurements, input levels, and amplitude measurement. In this blog, we will discuss about dual or triple spectrum analyzers.




Dual or triple spectrum analyzers- Dual or triple spectrum analyzers have a single unit, which generally work on two/three discrete inputs. Thus, they are also known as multi-input spectrum analyzers. These inputs can be measured and observed simultaneously.  Multi-input spectrum analyzers are used for real-time monitoring and for analyzing the required carriers on the identical screen.

When the rack-mount spectrum analyzer fails to work, then dual or triple spectrum analyzers are used which gives space saving benefits in a 1U package. They also support their own Ethernet connectivity. Moreover, if many screens are attached to the Guided User Interface, a real-time monitoring of the carriers can be done which carry different frequencies.

Performance and specifications-
  • Dual or triple spectrum analyzers are created for measuring and analyzing the carriers used for communications and broadcast, IF, L-Band carriers, executing uplink/downlink, and signals that are of 10MHz.

  • These signals are simple to store, monitor, and measure. It offers excellent performance and high amplitude accuracy.

  • The major purposes where it can be used are tracking, telemetry Command Systems often known as TT&C, spread spectrum, Wi-Fi signals, for satellite communications.

  • In addition to that, a zooming feature is also there that can be used to expand a miniature portion of a signal. You can observe a signal from -10dB to -50dB.

  • Remote controllable and monitoring via using a free remote control software

  • Small form factor and structure design

  • Well-defined and specific amplitude and frequency response

  • Can be executed with the OEM purposes

  • Invented for compact and movable satellites.

  • Easily blends into constrained spaces where area is crucial

Various types of spectrum analyzers are available in the market, but choosing the perfect one can be challenging. Avcom  Of Virgina has a huge range of reasonably priced spectrum analyzers. For any queries, you can call- (804) 794-2500.

A guide to the world of spectrum analyzers

A spectrum analyzer is a simple device to measure the signal strength in comparison with the full signal range of the device. The basic use of a spectrum analyzer is to measure the power of all signals -- known as well as unknown. They are an invaluable test equipment that is used in maintenance, test and design field of radio frequency circuitry. To a layman, a spectrum analyzer might look like an oscilloscope. But there is a basic difference between the oscilloscope and spectrum analyzer. While oscilloscope measures the signals in time domain, the spectrum analyzer measures them in the frequency domain.

Types of spectrum analyzer:

  1. Real-time
    Real-time spectrum analyzers compile the real-time bandwidth from the incoming signals in a limited time. They convert the information with the FFT algorithm. As the information is collected in real-time, there are no gaps in the calculated spectrum. To collect the range as far as Ku-band i.e. 14 GHz, an L-band spectrum analyzer is required.

  2. FFT/ Fast Fourier transform
    FFT spectrum analyzer is also called the Fast Fourier transform spectrum, analyzer. It has its own unique way of transforming a signal into their individual frequencies. The FFT analyzer requires the signal at least twice the bandwidth. Many individuals prefer to use the L-band spectrum analyzer to gather the maximum signal strength.

  3. Swept or superheterodyne
    A swept spectrum analyzer works best with a smaller bandwidth. With smaller bandwidths, it gives the maximum spectral resolution. This feature allows the full frequency range to be clearly analyzed and filtered accordingly.

  4. Audio
    Audio Spectrum analyzers are the wavelengths analyzers that are used by the sound engineers. It offers various volume levels of the frequency making it audible to humans. The method is aimed to give the engineers various audio sounds to analyze the harmonics of the signal.

How does a spectrum analyzer work?

Spectrum analyzer provides the users the opportunity to stop, center and start the frequency. The center frequency is the midpoint between the stop and start signals. It is also the axis for the range between the two. Different types of spectrum analyzer measure different signals in their own ways.  While it is difficult to find a good L-band spectrum analyzer that is also cost-effective, AVCOM has a huge range of reasonably priced spectrum analyzers.
