Spectral Analysis with a Vector Network Analyzer

Vector network analyzers (VNAs) are widely used in research, manufacturing, and service environments. In some cases, a VNA receiver can be used for simplified spectrum analysis, which might include detection of self-excitation, determination of signal power and harmonic level, or spectrum deviation from an expected reference spectrum, among other parameters.

Wireless Infrastructure Maintenance with a PC-driven VNA

A large wireless provider chose the Planar 304/1 VNA to test antenna feeders and RF duplexers in the field quickly and accurately because it delivered the performance they needed at a price they could afford. The PC-driven VNA fit into a space where no other bench instrument could, communicated test data via USB, and was easily automated for future tests, resulting in higher efficiency and less potential failure of the tower's elements.

Measuring Tunes of a Particle Accelerator with a VNA

CAMD was looking to replace their aging VNA with a more modern, programmable and affordable solution. Vector network analyzers are used in storage rings to provide a diagnostic measure of the “optics” of the electron beam as it passes through magnetic lenses. Through adjustments in the ring controls, the tunes can be guided toward desirable stable points and away from resonances which would decrease the beam’s intensity. Ideally, a portable VNA was desired so that it could be also used in maintenance and testing applications around the facility. The Planar TR1300/1 VNA was more affordable than a looming CRT replacement for CAMD’s legacy analyzer, which has been idle since the TR1300/1 arrived.

Using Planar 304/1 for Filter Design and Production

R&D Microwaves was looking to equip their test bench with a VNA for tuning bandpass filters in a prototyping and production environment. These tasks included straight tuning of low frequency VHF diplexers and measuring group delay and return loss. The Planar 304/1 VNA improved workflow, saving time and money in the process.

Why PC-Driven? How CMT Analyzers Improve Workflow and Security

PC-driven VNAs increase productivity and lower costs for test, quality control, and design applications, capitalizing on the ever-increasing performance of personal computers. Engineers using this format can downsize their equipment and experience significant productivity gains at a fraction of the cost of traditional analyzers.

Covariance Based Uncertainty Analysis with Unscented Transformation

Application of the unscented transformation (UT) and higher order unscented transformation (HOUT) are considered for uncertainty analysis. Using the principle that a set of discretely sampled points can be used to calculate mean and covariance, we can analyze nonlinear systems without the linearization steps and without defining the Jacobian matrix.

Residual Errors Determination for Vector Network Analyzers at a Low Resolution in the Time Domain

A method is introduced for determination of a VNA’s calibration residual errors for measurement of the reflection coefficient. The proposed method shows particular advantages when the use of a long verification line is impractical (e.g. at the wafer-level), or for measurements at low frequency ranges or similar cases when the resolution of conventional time domain methods is low. Experimental studies were conducted for two frequency ranges and in coaxial and on-wafer measurement environment. The proposed algorithm is a useful for a wide range of practical applications especially for measuring uncertainty estimation of cost-effective vector network analyzers.

Conference Presentation: OFDM Measurements, Validation and Troubleshooting

Implications of OFDM for some of the most popular digital performance test metrics, such as modulation-error ratio (MER), bit-error ratio (BER), constellation, and equalization, then offer some approaches for test and measurement of OFDM based on past experience and future possibilities.
