What is VNA software?

Engineers use vector network analyzer (VNA) software in conjunction with VNA hardware to measure and analyze the electrical performance of materials, components, devices, and systems. VNA software allows the test engineer to set test parameters and perform measurements via a graphical user interface (GUI). Network analyzer software offers various features, including data visualization, analysis, and manipulation, that enable RF engineers to characterize the behavior of components like amplifiers, filters, mixers, materials, and high-speed serial interconnects effectively. Our network analyzer software simplifies advanced measurements by guiding you through the setup and automatically analyzing the results. Popular VNA software includes: Noise Figure Measurements with Vector Correction network analyzer software which enables high-accuracy measurements of amplifier noise figure and noise power utilizing Keysight’s unique vector-source-correction technique. Time Domain Analysis network analyzer software, which allows RF developers to transform frequency domain data to time domain, or time domain data to the frequency domain. Vector and Scalar Mixer/Converter Measurements network analyzer software, which delivers fully calibrated conversion gain/loss, relative phase, and absolute group delay measurements of mixers and converters without the need for reference or calibration mixers. Automatic Fixture Removal network analyzer software, which allows engineers to characterize fixture effects and remove them from their non-coaxial device measurements. Materials Measurement Suite network analyzer software, which lets RF engineers determine the intrinsic electromagnetic properties of many dielectric and magnetic materials using a network analyzer, impedance analyzer, or LCR meter to measure the material’s response to RF or microwave energy.

Which software is used for network analysis?

Network analysis requires specialized hardware, but the accompanying software actually controls the measurements and analysis. We offer a range of software packages for controlling our vector network analyzers . These packages include features for calibration, measurement automation, data analysis, and reporting. Using this equipment, engineers conduct many different measurements, including: Scattering parameters (S-parameters), which describe how well device under test (DUT) transmits an RF signal at a given frequency. S-parameters relate to familiar measurements such as gain, loss, and reflection coefficient. Impedance measurements, including both real (resistance) and imaginary (reactance) components over various frequencies. Smith Chart analysis that visualizes complex impedance measurement data graphically. Group delay measurements quantify the time delay experienced by a signal as it passes through the device or component. For the complete list of network analyzer software, view our catalog .

How do I choose a VNA?

Selection criteria for a VNA varies based on the application or use case of interest. Typical selection criteria include frequency range, number of required ports from 2 up to 24 (multiport) or even 48 in a switch matrix, output power, and instrument class from economy to handheld to high-end. Once you understand the combination of specifications and functions you need, start evaluating different models to see which fits your current and future needs best. We recommend you consider these seven main network analyzer aspects before purchasing: Frequency Range Dynamic Range Measurement speed Trace noise Number of test ports Size Input power Beyond the box, evaluate the software capabilities offered, including an intuitive user interface and test automation features. Make sure to review compatibility with third-party software and programming languages as well. Additionally, identify the types of measurements you need to perform, the complexity of your measurement setups, and the calibration methods you intend to use. Also, consider the availability of technical support, warranty, and maintenance options from the VNA manufacturer or distributor.

Compare Noise Figure Measurement Performance Between the ENA-X and PNA-X Network Analyzers

The receiver quality and reliability of RF and microwave sub-systems such as satellite transponders or radar transmit/receive modules depends more on an LNA's noise figure than any other component's. Testing receivers operating in the FR1 and FR2 frequency bands requires accuracy and repeatability to ensure conformance with the latest standards. Learn how the ENA-X and PNA-X network analyzers simplify LNA characterization and how their noise figure measurement performance compares in this application note.
