TTR500 Series Vector Network Analyzer (VNA)

TTR500 Series Vector Network Analyzer (VNA)

A Vector Network Analyzer (VNA) is an electrical test instrument that uses a known Continuous Wave (CW) signal to measure the magnitude and phase response of Radio Frequency (RF) and microwave components, systems, and sub-systems in both design and manufacturing applications. It is an important test instrument that helps make wireless devices possible.

The Tektronix TTR500 Series 2-port, 2-path vector network analyzer gives RF design and validation engineers, education professionals, and manufacturing organizations the ability to accelerate their time-to-market by reducing prototype iterations and making everyday measurements with accuracy and confidence.

  • Patented DSP for dynamic range improvement
  • 3-year standard warranty

Learning curve? There is none


It's simple. Our industry-standard interface allows you to spend less time getting up to speed, so you'll have more time to test your design. The VectorVu-PC software delivers a traditional look and feel for controlling and calibrating the instrument with any Windows PC or laptop. For automated test systems, programmatic support is offered for common legacy VNAs for easy integration into existing test systems.


  • Run VectorVu-PC in offline mode to analyze stored data

  • SCPI command compatible with common legacy VNA

Have your own Vector Network Analyzer


Gone are the days of having to roll around a shared VNA. The TTR500's small, compact form factor and low price enables your company to have one on every engineer’s bench, improving efficiency and uptime. In education, an affordable vector network analyzer allows more students to get hands-on time with standard industry test instrumentation.


  • No need to rent or borrow VNAs, adding time and expense to projects
  • Small enough to slip into a briefcase or desk drawer
  • Share VNA displays, teach new concepts and review progress over PC networks
  • PC-based architecture (USB 2.0) provides convenient accessibility to your captured data

The next USB instrument, from the company that knows it best


Building on the success of our real-time USB spectrum analyzers, we’ve brought the same innovation and trusted form factor to the TTR500 Series VNA. The USB link separates measurement acquisition from analysis, providing a variety of benefits.


  • Upgrade quickly to the latest computer technology by simply replacing the PC
  • Choose the best display size for your application: tablet, laptop or external monitor
  • Use your own personal copy of VectorVu-PC, and keep your presets, file structure, and other settings just as you like them
  • Convenient file sharing using standard Windows networking for applications such as EDA tools
  • Improved reliability by removing common source failures – displays, control knobs, and processors
