Tektronix TTR503A Vector Network Analyzer
Price on request
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.
Legendary support and quality meets ease-of-use and affordability. The Tektronix TTR500 series 2-port, 2-path VNA is our latest breakthrough – an unmatched combination of measurement performance and convenience. Get the power to make everyday measurements with the accuracy and confidence you expect from Tektronix, all without breaking your budget.

Benchtop performance at a fraction of the cost
The TTR500 offers industry-leading price and performance. With more than 122 dB dynamic range and less than 0.008 dB RMS trace noise, the TTR500 has performance similar to expensive, conventional benchtop VNAs.
Compact and transportable: Take test where you need it
Gone are the days when you had to roll a cart with a heavy, shared VNA. Weighing under 3.5 lbs (1.59 kg), the TTR500 has a form factor small enough to fit in a briefcase. With a price tag to match, you can put a VNA on every engineering bench to improve efficiency and uptime. In a classroom, students can get hands-on experience with industry standard test instrumentation.
Performance, size, reliability, affordability – choose four
The TTR500A series VNA includes an impressive array of technological and patented advances that allowed us to bend many of the traditional trade-offs between RF performance, size, reliability, and cost.
Performance: Inside the VNA is a tightly integrated, single-board design. At its core lies a proprietary ASIC that implements all of the transmitting and receiving functions. Along with decades of experience in RF front-end and shielding design, this integration allowed us to implement advanced DSP and patented error correction techniques that dramatically improve measurement accuracy and dynamic range.
Convenience: Traditional benchtop VNAs have a computer inside that typically becomes obsolete by the time the product hits the market. Our architecture enables significant improvements in size, cost, and reliability by communicating over USB to your PC, while adding additional benefits and convenience. For example, run VectorVu-PC with other applications, share data seamlessly, and save individual application setups on your PC when multiple users share the TTR500.
Size: A compact single-board design without heavy input and display components allows the TTR500 to pack a lot of powerful functionality in a tablet-sized frame. Store it in a drawer, pack it in your briefcase, or carry it on a plane. Take quality test and measurement technology wherever you need it.
Reliability: In addition to reduced part count, integration on a singleboard consumes less energy than traditional benchtop VNAs. The board generates less heat, resulting in lower component stresses and higher reliability. A fanless design provides a quieter operation. We back all of this with a three year warranty.
Affordability: With fewer parts and an integrated design, we created a handheld VNA that delivers traditional benchtop performance and convenience at an unrivaled price. Why settle for less?
Integrated bias tee for active devices
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. Power the bias tee directly through BNC connectors on the rear panel.
Complete line of affordable accessories
To simplify shopping for the complete VNA solution, Tektronix offers a range of accessories for high-accuracy measurements. Select from calibration kits (electronic and mechanical), phase-stable cables, adapters, attenuators, rackmount, rugged carry case, and a training kit. See Ordering Information for a full list of available accessories.
Full 2-port 2-path S-parameter measurements
An independent RF source and three RF receivers for each port of the TTR500 enable you to take high-accuracy magnitude and phase measurements with a 1-port or 2-port device under test (DUT). Use the TTR500 to perform complete S11, S12, S21, and S22measurements of the DUT and display data in a variety of formats (see measurement functionality table).

Time domain with gating
Rapid measurement and analysis with VectorVu-PC
VectorVu-PC (available as free download) features an industry-standard interface that minimizes the learning curve so you have more time to test your design. The software delivers a traditional look and feel to control and calibrate the instrument, while providing touchscreen compatibility for Windows PC, laptop, or tablet. For automated test systems, we include a SCPI programming interface that is compatible with common legacy VNAs. A LabView driver is also available for analysis and control. See the TTR500 programmer manual for more information.
Offline simulation mode for convenient data analysis
VectorVu-PC features a simulation mode to analyze S-parameter data when disconnected from the TTR500. Capture measurements at the test site and analyze the data anywhere. Share it with your team or class when access to the TTR500 is limited.
Compatibility with EDA simulation tools
VectorVu-PC supports the Touchstone (S1P, S2P) file format to import and export S-parameter data in the simulation mode. You can also share data in this format with common EDA simulation tools.
Accelerate test with electronic calibration support
The Tektronix TCAL™ 500 makes calibration of Tektronix vector network analyzers fast, easy, and accurate. Cut calibration time down to roughly half the time compared to using traditional mechanical calibration kits. What normally takes 8 connections and 8 button-presses with a traditional cal kit, takes only 2 connections and 1 button press with the TCAL™ 500. The TCAL™ 500 is ideal for integration on production lines or R&D labs where speed, repeatability, and accuracy are critical.
Time domain measurements with gating
Time domain (TDR) measurements are supported as a field-upgradeable software license option to allow for S-parameter data to be analyzed in the time-domain. This is useful for detecting and locating faults in cables and transmission lines, analyzing impedance variations in connectors and traces, gating out the effects of fixtures and in-line elements, or simplifying filter tuning. Various supported modeled stimulus types include bandpass, lowpass impulse, and lowpass step.
