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

Ideal for Education

Don’t let the small form-factor fool you. Designed with a robust, industry-standard user interface, more than 122 dB dynamic range, and up to 6 GHz frequency range, the TTR500 VNA is the perfect instrument for preparing the next class of engineers. And with its extremely affordable price, more students can have hands-on time with a real-world instrument.


  • Full suite of 2-port 2-path VNA capabilities

  • Industry-standard and recognizable user interface

  • Import/export S-parameters in Touchstone (sNp.) file format

  • An offline mode well suited for out-of-lab assignments
