The Rigol RSA6000 spectrum analyzers are for RF and microwave signals test and measurement in telecommunications, audio engineering, and electronics for diagnosing signal performance, spectrum allocation, and detecting unwanted signals.

Summary points:

  • The RSA6000 series spectrum analyzers provide 200 MHz of bandwidth and 100 percent probability of intercept to enable engineers to detect transient signals like frequency hopping and pulses with precision.
  • With scanning speeds to 4 terahertz per second and coverage from 5 kHz to 26.5 GHz, the RSA6000 monitors ultra-wideband spectra, from low-frequency communications to microwave radar.
  • Equipped with five core measurement modes, the RSA6000 offers one-click switching for specialized RF testing and analysis to simplify complex engineering tasks.

PORTLAND, Ore. – Rigol Technologies Inc. in Portland, Ore., is introducing the RSA6000 series real-time spectrum analyzers to capture fleeting signals and help engineers build their ideal RF testing workstations.

The RSA6000 test and measurement instrument is built on the newly upgraded UltraReal system, and integrates signal capture, multi-dimensional signal analysis, and portable deployment.

The instruments analyze as much as 200 MHz of bandwidth with 100 percent probability of intercept POI to make transient signals like frequency hopping and pulses visible.

Tell me more about spectrum analyzers and how they work ...

  • A spectrum analyzer measures the magnitude of an RF and microwave input signal across a range of frequencies. It displays the signal's power as a function of frequency to help analyze the frequency content of signals. The device typically works by tuning to a specific frequency band and converting the signal into a time-domain waveform or a frequency-domain representation. Then it plots the amplitude power against the frequency to enable users to identify signal characteristics, noise, and interference. Spectrum analyzers are for telecommunications, audio engineering, and electronics for testing and diagnosing signal performance, spectrum allocation, and detecting unwanted signals.

In real-time spectrum analysis mode, scanning speeds as fast as 4 terahertz per second enable rapid scanning of ultra-wideband spectra to enhance efficiency in spectrum monitoring and interference detection.

The RF and microwave test and measurement instrument covers frequencies from 5 kHz to 26.5 GHz for diverse testing from low-frequency communications to microwave radar. Phase noise is as low as -108 decibels relative to the carrier at 1 GHz, 10 kHz offset to provide a clean benchmark for evaluating components like oscillators and phase-locked loops. Displayed average noise level is as low as -163 decibels per Hertz typical to capture weak signals.

The RSA6000 series integrates five core measurement modes to enable one-click switching to transform into specialized analysis tools. For more information contact Rigol Technologies online at www.rigolna.com/products/spectrum-analyzers.
