The TTR500 Series rivals the leading benchtop competition, at 40% lower price! It delivers better RF performance on key parameters like dynamic range and includes a built-in Bias Tee you may have paid extra for in the past. The new TTR500 Series VNA gives you all the capability and performance you need in a 6 GHz 2-port VNA at a price you can afford. Why settle for less?

  • Frequency Range: 100 kHz up to 6 GHz

  • Dynamic Range: Greater than 122 dB

  • Trace Noise: Less than 0.008 dBrms

  • Output Power: -50 to +7 dBm


Who uses Vector Network Analysers?

RF design and validation engineers use VNAs to validate their design simulations.

Manufacturing engineers assemble and test RF components and devices based on a certain set of specifications. Vector Network Analyzers are used to quickly and accurately validate the performance of the RF components and devices.

Education professionals train the next generation of engineers with standard industry test instrumentation.

VNA Application Examples
  • Antenna matching and tuning

  • Filter measurements

  • Amplifier measurements

  • Radio Frequency (RF) cable and connector measurements

  • 75 Ohm characteristic impedances
  • Automated production testing


Smart innovations, reduced cost and size


White Paper:

Performance, Size, Reliability, affordability. Choose four


The TTR500 Series VNA tightly integrates six RF receivers and two RF sources into a proprietary ASIC. With its innovative architecture and patented technology, the TTR500 Series VNA achieves the same level of performance as a benchtop VNA, but at 40 percent lower cost and one-seventh the size and weight of units with comparable performance.

  • Integrating RF capabilities into the ASIC provides higher reliability

  • 13 watt power draw means no noisy fan, low energy consumption

  • 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

  • Output file format compatible with common EDA simulation tools

  • SCPI command compatible with common legacy VNA



Ease of Use - Automatic Bandwidth Measurements


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

rsa-vna-family   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

Tek’s Vector Network Analyzer: How Does It Compare?

A wide variety of engineering disciplines use Vector Network Analyzers (or VNAs). Engineers involved in product development use VNAs at numerous stages in the design process. Component designers use VNAs to verify performance. System designers use VNAs to verify that system performance meets their subsystem and system specs. No matter the discipline, engineers turn to VNAs when they need to measure the inherent RF characteristics of passive or active devices.



We’ve put Tek’s TTR500 up against another industry VNA to see how well it performs. Check out this video.

Application Examples

RF Component Troubleshooting and Design Validation


Those who design, build, and manufacture RF components such as filters, cables, mixers, connectors, antennas, amplifiers and attenuators, need a powerful VNA to validate and troubleshoot to highly precise specifications. The TTR500 VNA is capable of fully characterizing the performance of both passive and active RF components up to 6 GHz, with more than 122 dB of dynamic range.

  • 100 kHz to 3/6 GHz frequency range

  • More than 122 dB dynamic range

  • Measure both passive and active components

  • Built-in bias tee included standard


Antenna Matching and Tuning

Minimize costly signal reflections by testing for impedance mismatches or discontinuities in your system. The TTR500 VNA is capable of measuring all four 2-port 2-path S-parameters in SWR, and complex impedance format. With its recognizable user interface, you can easily click, drag, couple, or decouple markers to smith charts or other traces, for easily analyzing measurements.

  • Measure full 2-port S-parameters in SWR and impedance formats

  • Smith chart markers in impedance, admittance, phase, real, imaginary

  • Click, drag, couple or decouple markers for analyzing measurments



If you’re integrating an off-the-shelf antenna with a wireless module, you’re need to ensure that the impedance of the antenna matches the impedance of the wireless module. Mismatch can result in reduced data packets, signal range and wasted battery life.

In this video, we show you how to improve the design and verify the performance of the antenna matching circuit placed between the antenna and wireless transceiver module, using the TTR500 Network Vector Analyzer.
