High Frequency Spectrum Analysers for Advanced RF Testing
High frequency spectrum analysers provide the bandwidth, dynamic range and low noise performance required for demanding RF, microwave and wireless applications.
Tektronix real time spectrum analysers offer wide frequency coverage, fast acquisition bandwidth and real time processing that captures transient and intermittent RF activity. These platforms excel in dense RF environments, radar testing, spectrum monitoring and electronic warfare analysis. They maintain strong measurement integrity with proven science behind their amplitude, phase and modulation accuracy.
VIAVI spectrum analysis modules within the OneAdvisor 800 provide RF spectrum measurements, signal quality assessment, interference detection and network performance verification, supporting complex telecom and 5G test requirements.
Portable and Handheld Spectrum Analysers for On Site Testing
Field technicians and RF engineers rely on portable spectrum analysers for fast, accurate testing outside the lab.
Bird SignalHawk analysers are rugged, lightweight and simple to use. They cover 9 kHz to 7.5 GHz with clear displays, waterfall views and statistical tools for interference hunting, channel power checks and WiFi signal verification. SignalHawk AOA models add angle of arrival capability, GPS mapping and enhanced measurement functions for rapid interference location and field strength assessments.
Tektronix RSA306B and RSA500 series analysers deliver benchtop grade performance in compact USB or battery powered formats. They are ideal for site surveys, EMI troubleshooting and general RF signal monitoring.
Digital and Real Time Spectrum Analysers for Comprehensive Analysis
Some applications require deep visibility into time varying or complex RF behaviour. Digital and real time spectrum analysers provide this level of insight.
Tektronix RSA600 and RSA7100B platforms deliver high fidelity RF capture, large real time bandwidth and powerful analysis software through SignalVu and DataVu. These tools support automated measurements, signal characterisation, real time triggering, recording and replay. They are suited to radar pulse analysis, transient detection, wireless standards testing and advanced research.
VIAVI OneAdvisor 800 integrates spectrum analysis, interference detection, cable and antenna testing and transport network validation into one instrument, making it valuable for operators managing multi technology wireless networks and 5G deployments.
Oscilloscopes vs Spectrum Analysers
Oscilloscopes show voltage changes over time. Spectrum analysers show power distribution over frequency.
If you need waveform shape, timing relationships or protocol decoding, an oscilloscope is the right tool.
If you need to measure channel power, harmonics, spurious emissions, interference or wireless signal behaviour, you need a spectrum analyser.
Both instruments complement each other, and many engineering tasks require both time domain and frequency domain analysis.

Browse the FAQs
What is a spectrum analyser used for?
A spectrum analyser measures signal amplitude versus frequency. It is used to detect interference, measure channel power, verify transmitter performance, troubleshoot RF issues and analyse wireless or digital communication signals.
What is the difference between an oscilloscope and a spectrum analyser?
An oscilloscope shows signals in the time domain. A spectrum analyser shows signals in the frequency domain. Oscilloscopes show waveform shape and timing, while spectrum analysers show power, frequency content and interference.
Are portable spectrum analysers reliable?
Yes. Modern handheld and portable models from Bird and Tektronix provide accurate RF measurements in rugged field-ready designs.
How do RF spectrum analysers help in WiFi and wireless testing?
They reveal channel congestion, interference, noise and signal strength across WiFi bands, helping improve network performance and coverage.
Which industries commonly use spectrum analysers?
Telecommunications, defence, aerospace, broadcasting, automotive, electronics manufacturing, research labs and universities.
