WSA5000 Real-Time Spectrum Analyzer (RTSA)

Powerful, Versatile and Cost-Effective !!

The WSA5000 RTSA has all the power you expect from a traditional lab spectrum analyzer.

  • 100 kHz to 8, 18, or 27 GHz Frequency Range
  • Real-Time Bandwidth (RTBW) up to 100 MHz
  • Probability of Intercept (POI) as short as 1.02 μs
  • Spurious Free Dynamic Range (SFDR) up to 100 dBc



A Real-Time Spectrum Analyzer (RTSA) processes RF signals at a speed fast enough as to not miss any signals for its given captured bandwidth, known as its Real-Time Bandwidth (RTBW) or Instantaneous Bandwidth (IBW). In addition an RTSA needs to provide views of the spectrum in the frequency and time domains, as well as power spectral density to enable analysis of signals that may be so fast as to be undetectable to the human eye. And finally an RTSA must provide the capability to trigger on events and capture them, and record them for playback enabling deeper analysis.

Applications :

Anyone dealing with signals that may vary dynamically in amplitude or are agile in frequency.

Examples include:

  • Short duration intermittent signals such as pulsed radar systems, frequency-hopping spread spectrum radios, pulse modulated radios;
  • Multi-signal environments such as ISM bands – 915 MHz, 2.4, 5.8, 24 GHz;
  • Unwanted signals such as unintentional or self-interference, intentional interference (jammers), and listening devices (bugs).

The ThinkRF WSA5000 RTSA is a powerful and cost-effective spectrum analyzer designed to work across a variety of different applications. It receives commands and transmits data using a high speed GigE connection which means it can be controlled and monitored remotely. In combination with our full-featured RTSA software, the ThinkRF WSA5000 RTSA is a complete solution for your spectrum analyzer needs.

The ThinkRF WSA5000 is a PC-controlled Real-Time Spectrum Analyzer (RTSA) which includes:

  • 100 kHz to 8, 18 or 27 GHz frequency range
  • Real-time spectrum graph
  • Real-time spectrogram view
  • Real-time power spectral density display (persistence)
  • Real-Time Triggering
  • Real-time I/Q plots
  • Real-Time Recording and Playback

The WSA5000 can be utilized anywhere in the wireless ecosystem – R & D, Education, Manufacturing, Deployment, and Monitoring.

Horizontal Rack MountHorizontal Rack Mount


The Horizontal Rack Mount allows you to secure two WSA5000 RTSA devices in 1U of a standard 19″ equipment rack. It also works as the base for the optional vertical mount kit described below.

Vertical Rack Mount (Add-on)2013-11-08-Think-RF-shelf-vertical


The Vertical Rack Mount is an add-on for the Horizontal Rack Mount. It provides vertical brackets for securing up to six WSA5000 RTSA devices in 4U of a standard 19″ equipment rack. (Please Note: This is not a standalone kit, it must be used in conjunction with the Horizontal Rack Mount kit.)

Wall MountThinkRF_Wall_Mount


The Wall Mount is a mounting system for the WSA5000 RTSA. It allows you to cleanly secure the device to most surfaces for remote operation and spectrum analysis.
