Best Spectrum Analyzer In The Market

Spectrum analyzers are scientific instruments that are used to collect signals of all kinds – whether they be electric, magnetic, acoustic, or radiation signals. Spectrum analyzers can pick up signals in a wide frequency range and also present this information in a manner known as a displayed plot. These plots allow you to view the frequency spectrum and pinpoint the signal of your interest.

We have compiled a list of the ten best spectrum analyzers for you to consider. Moreover, we have also included a buyer’s guide to help you get started.

How to Choose Spectrum Analyzer

Best  Spectrum Analyzer

Spectrum Analyzers are invaluable tools for anyone working with radio frequency signals. Whether you are a repair technician, an RF engineer, a student, or a hobbyist, you will at some point need to measure and possibly even analyze RF signals. This is where a spectrum analyzer comes in.

For this review, we picked four different types of analyzers: Benchtop, Handheld, Modular, and the Cheapest Ultra-Portable Spectrum Analyzer. As a result, we present you, the reader, with a diverse set of products each with its own unique set of tradeoffs. You might not want to take the Siglent SSA3021X-TG out into the field. Instead, you’d want to take the RF Explorer into the field to make outdoor measurements of various signals. Similarly, you would not want to use the TinySA for your lab R&D applications in which a high degree of measurement accuracy is desirable.

We looked at many different parameters but here is the list of the top ones we considered.

Frequency Measurement Range

The frequency measurement range is the frequencies that the spectrum analyzer is able to sweep across. This is the most important factor to determine at the first step of buying a spectrum analyzer.

If you are going to test a Wi-Fi signal, then the spectrum analyzer must cover a frequency range that includes at least 2.4 GHz. In other words, what you are going to face will determine the frequency range of the analyzer you have to afford. When you’re using a spectrum analyzer with 9 kHz to 1.5 GHz of the frequency range, it means you are not able to inspect the Wifi signals because it operates at 2.4 GHz and 5 GHz frequencies.

The higher the frequency range, the more expensive it generally charges. A great spectrum analyzer has to cover a greater frequency range to support as many applications as possible.

SPECIFICATIONS

We studied the key specifications of every spectrum analyzer. For instance frequency range, bandwidth, sensitivity, and dynamic range. Hardware specifications are an indicator of what kind of signals can be processed by the Spectrum Analyzer. In general and as one might expect, as the specifications such as frequency range go up, so does the price tag.

DISPLAY

A Spectrum analyzer should have a clean sharp display that’s as large as possible relative to the total size of the instrument. Traces and markers are typically displayed in different colors, so you should be able to differentiate between them. As well, where it makes sense, a display must be responsive to user input.

PRICE

The price point should be consistent with the functionality. In this article, we have reviewed spectrum analyzers at different price points – from sub-$100 to about $12,000. The cheapest one on our list, the TinySA is a great learning tool and for limited testing. But don’t use it to test the quality of RF signals or any serious parametric testing. For that, you would need to either use the Siglent SSA3021X-TG or the Tek RSA507A.

CUSTOMER FEEDBACK

When you spend over $2000 on an analyzer you want to ensure that you have access to a reliable support organization and if the instrument breaks down, you can get quick service. The Siglent SSA3021X-TG for instance is repaired in Ohio, so you’re not waiting weeks for it to go halfway across the world for repair. 

USABILITY

The usability of an instrument is a key consideration. For instance, a standard, uncomplicated and intuitive interface is an important attribute. All the analyzers we picked were highly usable with nothing overly complicated to hinder ease of use.

POPULARITY

We picked spectrum analyzers that are popular among many users. This way, we could check out reviews left by previous users with verified purchase history.

Type of Analyzers

The most expensive model is the benchtop model. This model is great to use for labs or stationary locations. If you tend to carry the analyzers anywhere you want, then choose from the portable options. The handheld one is more affordable and portable but the functions are limited. This factor may not be critical but determines the convenience of your work.

FAQ,s

1. What is a good spectrum analyzer?

The best spectrum analyzer for beginners that field professionals recommend is either the Ragol DSA815-TG, or the Siglent SSA3021X, or the Oscium Wipry 2500x.

2. How do I choose a spectrum analyzer?

The resolution bandwidth is the bandwidth of the IF filter, which determines the selectivity of the spectrum analyzer. Wide resolution bandwidth is required for wide sweeps while a narrow filter is used for narrow sweeps. By using narrower resolution bandwidths, the instrument can reveal sidebands.

3. Does Logic Pro have a spectrum analyzer?

In Analyzer mode, the main display shows the frequency spectrum of the input signal as 31 or 63 independent frequency bands. The Analyzer parameters are used to activate Analyzer mode and to customize the appearance of the incoming signal in the main display.

4. Can you use NanoVNA spectrum analyzer?

The NanoVNA made network analyzers cheap enough for almost everyone. … When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 0.1MHZ-350MHz, UHF square wave output between 240MHz-960MHz

5. Can you use an oscilloscope as a logic analyzer?

If you don’t have a Bus Pirate or Logic Sniffer lying around, [Joonas] has a great MacGyverism that turns an oscilloscope into the simplest logic analyzer ever. The basic premise of the build is tying four digital lines to the analog input of an oscope.

Conclusion

The choice of the best spectrum analyzer is not an easy one. Research should be conducted before making a purchase. Because these devices are very expensive, you don’t want to get the wrong one. All of them are designed for a specific kind of work, so it is best to do a thorough research beforehand. The devices are quite expensive, but they are worth every penny.

They are designed specifically to be fast and compatible with other devices such as PCs and laptops. If you want to get the top audio spectrum analyzers, you should consider the features mentioned above. There are several brands to choose from, all of which are of excellent quality.

Now, you can choose the right one from the shortlist based on your requirements.

Good wishes to you !!!
