Key Uses & Functions of Spectrum Analyzers

Frequency Analysis
Measure and display the amplitude of signals across a range of frequencies to identify spectral content.

Harmonics and Spurious Signal Detection
Detect unwanted signal components, harmonics, and spurious emissions that may affect system performance.

Wireless Communication Testing
Analyze modulated signals and evaluate signal quality for wireless standards like LTE, 5G, and Wi-Fi.

Real-Time Spectrum Monitoring
Capture transient or intermittent signals that traditional swept analyzers might miss.

Power Measurements
Measure signal power accurately across frequency ranges to ensure compliance and optimal performance.

Interference and Noise Analysis
Identify and characterize sources of electromagnetic interference or noise in complex systems.

Automated Testing and Data Logging
Integrate with software to perform repetitive measurements and log results for analysis and reporting.

EMI Pre-Compliance Testing
Screen devices for electromagnetic interference before formal compliance testing, reducing the risk of costly test-lab failures.
Types of Spectrum Analyzers by Keysight
Explore the most common Keysight spectrum analyzers available on Tekmark.

Basic Spectrum Analyzers
Entry-level analyzers for cost-effective RF monitoring, education, and basic troubleshooting. These provide essential spectrum analysis functions without the complexity or cost of full signal analyzers.
Available models on Tekmark: N9321C (up to 7 GHz), N9324C (up to 20 GHz).

X-Series Signal Analyzers
High-performance benchtop analyzers for R&D, design validation, and wireless communications testing. The X-Series supports advanced modulation analysis for 5G NR, LTE, Wi-Fi, and radar signals with frequency coverage up to 50 GHz and beyond.
Available series on Tekmark: CXA (basic), EXA (mid-range), MXA (advanced), PXA (premium), UXA (ultra-wide bandwidth)

Modular PXI Analyzers
Compact, modular spectrum and signal analyzers for integration into automated PXI-based test systems. PXI analyzers enable scalable, high-throughput RF measurements for production test and lab automation.

FieldFox Handheld Analyzers
Portable, battery-powered RF analyzers for field troubleshooting, tower maintenance, and on-site signal verification. FieldFox combines spectrum analysis, cable/antenna testing, and optional vector network analysis in a rugged, MIL-PRF-28800F-rated enclosure.
Available series on Tekmark: N991xA/B (up to 9 GHz), N992xA/B (up to 26.5 GHz), N993xA/B (up to 44 GHz).
