Spectrum Analyzer (Signal Analyzer)

Choose from an extensive selection of signal analyzer products from DC to 50 GHz, extendable to 1.1 THz with external mixers, for your spectrum analysis measurements.

A signal analyzer combines swept-tuned spectrum analysis to maximize dynamic range for out-of-band distortion and vector signal analysis to accurately measure in-channel distortion. This combination allows for accurately measuring frequency, amplitude, spurious, phase noise and modulation analysis of communication signals without sacrificing dynamic range and speed.

Combine your spectrum analyzer or signal analyzer with 89600 VSA software for deep vector signal analysis in R&D or X-Series measurement applications for easy demodulation of a broad range of standard-based and general-purpose digital signals and formats. Upgradable real-time spectrum analyzer capabilities ensure that you see, capture, and understand the most elusive signals - known or unknown.

If you are primarily making in-channel measurements, you might be interested in vector signal analyzers, which are optimized for fast measurements of known signals.
