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.
Vector Network Analyzer advantages
A VNA allows you to measure complex quantities such as reflection coefficients, impedance, admittance, return loss, insertion loss, gain, isolation, and much more in a manner that is not possible with other test instruments.
Traditional test equipment such as power meters, spectrum analyzer, and oscilloscopes typically only have receivers that are used to measure signals emitted or created by the Device Under Test (DUT). In contrast, a VNA has both a source and a set of receivers used to determine changes to the stimulus caused by the DUT. The stimulus-based test approach allows VNAs to measure very small reflections and changes to the stimulus enabling you to accurately characterize any RF component in real-world environment and test conditions.
Who uses Vector Network Analyzers?
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

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.

Antenna Matching and Tuning
You built your antenna and transceiver. Now you want to see how well it performs. Minimize costly signal reflections and maximize signal range by testing for impedance mismatches or discontinuities in your system using the TTR500 VNA. Thanks to its USB design and easy to use interface, the TTR500 makes analyzing impedances or admittances on the Smith chart and saving S-parameter files, for the purpose of designing matching networks, seamless and convenient.
- Measure S-parameters in Log Magnitude, Phase, SWR, impedance, and admittance formats
- Smith chart markers in impedance, admittance, phase, real, and imaginary
- Conveniently import/export S-parameter files in Touchstone (.sNp) file format directly to your PC
- Save traces to memory for comparison with live results
You have a filter to test and you want to see low loss and high rejection at the correct frequencies. While other types of test equipment can measure overall performance, VNAs allow the user to fully characterize filters within their intended operating frequency and power level, allowing for complete comparisons to design simulations. The TTR500 VNA is capable of measuring return loss, insertion loss, group delay and much more for both tuning and validating filter performance.
- Tune and characterize filters by measuring return loss, insertion loss, group delay and much more
- Simplify test procedures by taking advantage of automated bandwidth and notch measurements
- Optimize dynamic range and measurement speeds by adjusting IFBW from as low as 10 Hz to 300 kHz
- Measure high dynamic range cavity filters using the TTR500's >122 dB dynamic range
Your amplifier has to deliver sensitivity to a receiver, and high power as an output. The TTR500 allows you to fully characterize amplifier performance for comparing to design simulations. Use the built-in bias tee (standard in both models) to provide a DC bias to active devices without the expense and complication of external circuitry. Unlike some other USB-based VNAs, the TTR500 series VNA is capable of measuring both passive and active devices including medium to low-power amplifiers.
- Measure amplifier impedance match, gain, phase, group delay, and isolation
- Built-in bias tee accessible on both ports to conveniently bias active devices
- Capable of a wide range of output power levels for determining P1dB compression points
- Source and Reciever Calibration for higher precisision power measurements
RF Cable and Connector Measurements
If you have a pile of cables or connectors and you want to characterize their S-parameters, or if you simply want to know if they're any good, you can with the TTR500 series VNA. Capable of measuring as much as 40 dB of return loss, the TTR500 series VNA has the calibration and measurement performance required to properly characterize these important RF components.
- Characterize RF cables and connectors with as much as 40 dB return loss
- Calibrate once, and measure for a week: less than 0.1 dB of drift over 90 hours
- Built-in functions such as Port Extension allow for properly dialing in calibration planes
- Simplify test procedures by saving and recalling calibration state files
- Locate and troubleshoot cable/PCB impedance discontinuities with the Time Domain with Gating option.
