Difference between Spectrum Analyzer and Oscilloscope

In electronic laboratories or some field areas, they are one of the most vital electric equipment used very regularly. Both Spectrum analyzer and oscilloscope are essential tools for analyzing and viewing electric signals. They serve a purpose in viewing and analyzing signals from a microphone, radios, TVs, cell phones or other electronic devices. Before we understand the difference between a spectrum analyzer and an oscilloscope, let’s first see what are the functions they both perform. 

What is a spectrum analyzer?
A spectrum analyzer is used to determine the magnitude of an input signal versus frequency. It is in the form of electronic equipment that measures the magnitude of an input signal against the frequency range of the instrument. This means it measures the spectrum powers of both the known and unknown signals in electrical equipment.

A spectrum analyzer can be used for different types of measurements in field services or in test laboratories.

What is an oscilloscope?
An Oscilloscope is an electric equipment that measures the magnitude of an input signal versus time. The primary purpose of an oscilloscope is to give a signal’s voltage Vs time graph. Mainly, it gives all-inclusive information about the timing relationships of various identified signals.

It finds out the relative delay of timings between two separate signals.

Difference between Spectrum Analyzer and Oscilloscope

When you want to identify all characteristics of an electric signal, the oscilloscope is not ideal electronic equipment. To identify and analyze the characteristics of mixers, detectors, amplifiers, frequency, spectrum analyzers are needed by the engineers. However, the oscilloscope is the most preferred choice for real-time bandwidth measurement.

Spectrum analyzers Vs  Oscilloscope functionalities

• Oscilloscope measures amplitude in volts
• It can evaluate low voltage and frequency.
• An oscilloscope can measure transient signals.
• Preferable for real-time bandwidth measurement
• Spectrum analyzers evaluate amplitude in DBM
• Used for measuring long-term short term frequency stability.
• It may not be suitable to measure some transient signals.
• Spectrum analyzers are superior when it concerns with higher sensitivity

To know when to use these two, you should be familiar with the functions of each equipment.

How To Select Spectrum Analyzer Software?

Are you in a dilemma about which spectrum analyzer to choose? Apart from testing the parameters of spectrum analyzers, you need to keep in mind its architectural types. With the technology advancements, spectrum analyzers have also evolved. There are many different types of spectrum analyzer software systems designed using different technologies. Although the goal of each spectrum is the same, the functionality is different.

For choosing the right spectrum for your application, you need to understand the types available. Compare and see their individual work and then decide what suits your application the best.

Swept spectrum analyzer: A swept spectrum analyzer is a test instrument that has been using analog techniques in its functionality. It dominated the market for almost 50 years. They work on a simple principle that is measuring each frequency sequentially. The current types of swept spectrum analyzers make use of digital techniques in the main. The earlier swept types still operate on analog techniques.

FFT spectrum analyzer: As compared to analog techniques, digital technologies have better performances. In fact, they are more affordable than the spectrum analyzers using analog techniques. FFT spectrum analyzer software applies digital technology where all the signals change into digital formats and the analysis of signals is done by FFTs (fast Fourier transform).

After this, the signals are converted into a display format or a format that can be analyzed.

Real-time spectrum analyzer: In real-time spectrum analyzers, the performance of FFTs is very fast, that means, virtually in real-time. Because of this, the signals that might not be visible can be detected. It can capture temporary as well as fast signals more quickly. This type of analyzer collects data in the time domain and further converts it into the frequency domain through FFTs.

USB spectrum analyzer: As the name tells, this spectrum analyzer can be connected to a computer via a USB interface. They are also cost-effective. Also, you can see the processing on a computer screen.

While choosing spectrum analyzer software, there are also other factors that need to be considered. For example, cost, performance or attainability. So keep all these points in mind before choosing the right instrument.
