Abstract

Verification is an important step in scattering parameter (S-parameter) measurements to ensure the validity of the calibration of a vector network analyzer. This paper discusses specific aspects of vector network analyzer verification concepts that have been established recently as part of a European metrology research project.

... In order to compare one-dimensional measurands in a bilateral interlaboratory comparison, different metrics for the degree of equivalence can be found in (DIN ISO 13528, 2020). However, there is only little information available on interlaboratory comparisons for higher dimensional measurands (MUBARAK, 2016), such as tristimulus values. Therefore, we want to provide some insights into the degree of equivalence evaluation for higher dimensional measurands, where measurements in the CIE1931 xyY colour space are considered. ...
... In this paper, we propose that treating the luminance as a one-dimensional measurand is appropriate; chromaticity coordinates however, shall be treated as two -dimensional measurands. A procedure for determining the degree of equivalence fo r higher dimensional measurands was evaluated (MUBARAK, 2016). This approach is applicable to most light sources, including white LEDs. ...

There is only little guidance available for the evaluation of the degree of equivalence for higher dimensional measurands, especially in respect to tristimulus values. Currently, the tristimulus values are usually treated as one-dimensional measurand in order to simplify the degree of equivalence evaluation and be able to use the well-known procedures and statistics known from one-dimensional measurands. As the tristimulus values are clearly a high-dimensional measurand, they should be treated in that way. In the following, a procedure for the degree of equivalence evaluation for high-dimensional measurands is presented where the Monte Carlo method is used to support a clear understanding of the procedure. In addition to the procedure, the limitations of this method are discussed in regard to tristimulus values.

This paper describes some investigations, made using electromagnetic modeling, into the uncertainty for a cross-guide verification standard of transmission loss for waveguide Vector Network Analyzers (VNAs) operating at millimeter-wave frequencies. The cross-guide is calculable and can be made traceable to the International System of units (SI) via precision dimensional measurements of the waveguide aperture and flange. The measurement errors due to dimensional tolerances of the cross-guide line (including waveguide aperture height, width, corner radii and waveguide line length) and the mechanical discontinuity between the cross-guide and the VNA test ports (including the connection angle) can be predicted from electromagnetic theory. The measurement uncertainty due to these errors can be calculated according to the Law of Propagation of Uncertainty. The paper describes these details, and compares experimental results, obtained using a VNA operating in the 140 GHz to 220 GHz band, with simulated values evaluated by electromagnetic modeling software.

This paper describes some investigations into establishing primary standards of loss for waveguide Vector Network Analyzers (VNAs) operating at millimeter- and submillimeter-wave frequencies. The standards comprise straight sections of waveguide, where the waveguide line is orientated such that the waveguide aperture is at right-angles to the waveguide apertures on the VNA test ports. This 'cross-connected' waveguide forms a section of waveguide that is effectively below cut-off. The mechanical discontinuity between the cross-connected waveguide and the VNA test ports also generates significant reflection. The combined effect due to these two loss mechanisms - cut-off attenuation and discontinuity reflection loss - can be predicted from electromagnetic theory and so can be used to establish sections of cross-connected waveguide, of various lengths, as primary standards of loss. The paper describes these standards in detail and compares experimental results, obtained using a VNA operating in the 50 GHz to 75 GHz band, with values predicted by electromagnetic modeling software.

Radio-frequency (RF) scattering parameters (S-parameters) play an important role to characterise RF signal transmission and reflection of active and passive devices such as transmission lines, components, and small-signal amplifiers. Vector network analysers (VNAs) are employed as instrumentation for such measurements. During the last years, the upper frequency limit of this instrumentation has been extended up to several hundreds of GHz for waveguide measurements. Calibration and verification procedures are obligatory prior to the VNA measurement to achieve accurate results and/or to obtain traceability to the International System of Units (SI). Usually, verification is performed by measuring well-matched devices with known S-parameters such as attenuators or short precision waveguide sections (shims). In waveguides, especially above 110 GHz, such devices may not exist and/or are not traceably calibrated. In some cases, e.g. filter networks, the devices under test (DUT) are partly highly reflective. This paper describes the dependency of the S-parameters a) on the calibration procedure, b) on the applied torque to the flange screws during the mating process of the single waveguide elements. It describes further c) how highly-reflective devices (HRD) can be used to verify a calibrated VNA, and d) how a measured attenuation at several hundreds of GHz can be substituted by a well-known coaxial attenuation at 279 MHz, the intermediate frequency (IF) of the VNA, to verify the linearity. This work is a contribution towards traceability and to obtain knowledge about the measurement uncertainty of VNA instrumentation in the millimetre-wave range.

This paper presents an investigation of verification artifacts in WR-03 waveguides. The waveguide verification artifacts include a cross-guide and a custom-made circular iris section. The investigation involves the transmission loss uncertainty analysis of the verification artifacts for vector network analyzer (VNA) waveguide systems operating at millimeter wavelengths. The measurement errors due to the dimensional tolerances and the flange misalignment are predicted by using a commercially available electromagnetic software package. The data analysis is carried out for complex-valued scattering parameters (S-parameters). The uncertainty due to different error sources is computed according to the Law of Propagation of Uncertainty. The real and imaginary data along with the associated uncertainties are converted to magnitude and phase representation via linear propagation of uncertainties. The experimental results are also compared with simulated results.

In this paper, the design and analysis of a novel coaxial type N verification standard based on an air-line is presented. The measurement uncertainty budget is computed by taking into account the mechanical and dielectric tolerances, thus allowing to determine the transmission loss uncertainties of the verification standard. The calculated results are obtained by using commercially available electromagnetic software. The data analysis is carried out for complex-valued quantities. The measurement uncertainty due to different error sources is computed according to the Law of Propagation of Uncertainty. Simulated and experimental results are compared to demonstrate the applicability of the approach.

In this paper, 3D electromagnetic simulation is used to predict the attenuation of a length of reduced aperture waveguide (RAW) and to estimate the uncertainty in the predicted attenuation due to imperfect dimensions and alignment of the waveguide. This allows the RAW to be used as a calculable standard for the verification of mm-wave waveguide vector network analyzers (VNAs). The VNA is verified if the attenuation of the RAW measured on the VNA agrees with the predicted attenuation to within the uncertainties.

For years, measurement inconsistencies were observed between calibration methods, such as sliding load, TRL and offset short, especially at frequencies above 18GHz. Measurement repeatability was another frustrating experience for practitioners of high precision measurements, such as TRL calibration. The “connector effect” was discovered recently. It provided the framework that these measurement inconsistencies and repeatability can be explained. This paper will review the observed measurement issues, present the theoretical base of the connector effect and show how VNA measurement accuracy can be improved.

This paper presents a detailed investigation of the influence of pin gap size on the S-parameters of the 1.85 mm connector. In contrast to earlier publications connector geometry is simulated with all chamfers, gaps and contact fingers. Simulation results are verified by cross-checking between finite element frequency domain and finite difference time domain methods. Based on reliable simulation results, a very fast tool was developed to calculate S-parameters for a given connector geometry. This was done using database and interpolation techniques. The most important result is that very small pin gaps in conjunction with large chamfers have a drastic impact on connector S-parameters for frequencies above 50 GHz.
A procedure performed by using a genuine two-port reciprocal network instead of a standard 'thru' in a full two-port error correction of an automatic network analyzer is presented. Although it can be applied to any type of waveguide system, the proposed technique is particularly useful with noninsertable coaxial or one-wafer devices. Experimental comparisons show that the suggested procedure provides a great degree of accuracy.< >
