Viavi Spectrum Analysers: Essential Tools for Signal Measurement

Spectrum Analysers

These are powerful tools that help you to see and understand invisible radio waves and electrical signals. They work like special radios that can show you the strength of different frequencies on a screen, kind of like a graph. 

These devices are super important for people who work with wireless technology, radio communications, and electronics. Engineers and technicians use spectrum analysers to check if signals are working correctly, find problems in wireless networks, and make sure electronic devices are sending out the right kind of signals. 

At Fluxnet, we offer a range of spectrum analysers to fit different needs and budgets. Our prices are reasonable, making these essential tools accessible to professionals, small businesses, and even hobbyists who want to explore the world of radio frequencies.

• Vector Signal Analysers
• Fast Fourier Transform (FFT) Analysers
• Audio Spectrum Analyser 

Key Features of Spectrum Analysers

• Frequency Range and Bandwidth: Spectrum analysers measure signals over a range of frequencies, from a few Hz to hundreds of GHz. Bandwidth shows how many frequencies can be analyzed at the same time. Different models offer different ranges and bandwidths for various uses.
• Resolution and Accuracy: This includes the resolution bandwidth (RBW), which helps the analyser tell apart signals that are close together. Amplitude accuracy ensures power measurements are precise. Higher resolution and accuracy lead to better and more reliable signal analysis.
• Display and Analysis Capabilities: Modern spectrum analysers have advanced display options and tools. They can perform real-time spectrum analysis to capture quick signals, show different display modes (like spectrograms and waterfall plots), and have built-in functions for measuring things like channel power and harmonic distortion.
• Input Sensitivity and Dynamic Range: Input sensitivity tells you the weakest signal that can be measured. Dynamic range shows the difference between the strongest and weakest signals that can be measured at the same time. These features are important for analyzing both weak and strong signals together.
• Connectivity and Form Factor: Spectrum analysers come in different styles, such as benchtop, portable, handheld, and networked. They usually have various connectivity options (like USB and Ethernet) for data transfer and remote control. Some models also include features like built-in tracking generators and compatibility with external software for advanced analysis.

Uses

• RF Testing: Spectrum analysers are essential for testing and characterizing radio frequency signals in various wireless devices and systems.
• Signal Analysis in Telecommunications: They are used to analyze and troubleshoot signals in telecommunication networks, ensuring proper signal quality and performance.
• Pre-compliance Testing: Spectrum analysers help manufacturers conduct pre-compliance tests to ensure their products meet regulatory standards for electromagnetic emissions.
• Interference Detection: These tools are crucial for identifying and locating sources of interference in wireless communications and electronic systems.
• Research and Development: In R&D labs, spectrum analysers are used to develop and optimize new wireless technologies, antennas, and RF components.

Choosing the Right Spectrum Analyser

When choosing a spectrum analyser, there are several important factors to consider:

• Frequency Range: Make sure the analyser covers the frequency range you need for your specific applications. Different models offer ranges from a few Hz to hundreds of GHz.
• Resolution and Accuracy: Look for an analyser with appropriate resolution bandwidth and amplitude accuracy for your measurements. Higher resolution allows you to distinguish between closely spaced signals.
• Real-Time Capabilities: If you need to capture transient or dynamic signals, consider a real-time spectrum analyser. These can detect short-duration events that traditional swept analysers might miss.
• Additional Features: Consider what extra functions you might need, such as built-in tracking generators, vector signal analysis, or specific measurement modes for your applications.
• Cost: Spectrum analysers come in a wide range of prices. Balance your budget with the features you need. Remember that while high-end models offer more capabilities, they may be overkill for simpler applications.

At Fluxnet, we offer a variety of spectrum analysers to suit different needs and budgets. Our team can help you find the right balance between features and cost, ensuring you get an analyser that meets your requirements without unnecessary expense.
