CISPR A and ANSC C63® Overview on Site Validation Measurements from 18 GHz to 40 GHz
By Nicholas Abbondante, Intertek, Boxborough MA
邦訳: 18GHz を超える周波数での FCC要求に対する試験は長年にわたって行われており、最大 231GHz まで拡張されています。 ただし、この周波数範囲に対して開発された試験サイトの検証方法はこれまでありませんでした。 18GHz 未満で認定されたサイトはその周波数を超えても許容されると想定されてきましたが、これはデータに基づいたものではありませんでした。 25GHz および 38GHz 以上で動作する送信機の出現により、サイト検証がより重要になり、遠方界と測定アンテナビーム幅内での試験が更に困難になりました。C63.25.3 ワーキング グループの目標は、18GHz から 40GHz までのサイト検証方法を開発して、将来の測定の有効性と再現性を強化し、遠方界試験の問題の解決に役立つコンパクト アンテナ テスト レンジ (CATR)やリバブレーションチャンバーなどの代替テスト サイトの検証と相関関係を提供することです。

邦訳: アンテナ校正と試験サイトの検証は、どちらも試験環境での正確なアンテナ測定が必要なため、相互に依存するプロセスです。 CISPR 16-1-4 または C63.25 で指定されているサイトVSWR は、1GHz ～ 18GHz の試験サイトの性能を評価するための性能指数として使用されます。 CISPR法では、定在波は、いくつかの線形パスに沿ってスカラーフィールドをサンプリングすることによって測定されます。 ただし、測定を簡素化するために、試験データのサンプリングが大幅に少なくなっています。 C63.25.1 (1 ～ 18 GHz) で規定されているタイムドメインSVSWR は、アンダー サンプリングの問題に対処するために開発されました。 18GHzを超える試験では、クワイエット ゾーン(QZ) 内のより多くの場所をテストしたり、受信アンテナビームカバレージを測定したりする必要性など、新たな課題が生じます。 その結果開発されたシリンドリカル モード フィルター SVSWR は、現在 C63.25.3 (18 ～ 40 GHz) および CISPR 16 標準で積極的に検討されています。 セミナーの参加者は、テスト方法の進化の技術的背景 (何が、なぜ) と、さまざまな技術的課題の解決に高度なアンテナ測定技術がどのように使用されているかについて、より深い理解を得ることができます。

邦訳: 従来のアンテナテスト設備は通常、特定の測定アプリケーションを念頭に置いて設計されており、その結果、これらの設備は単一の固定測定ジオメトリで構成される傾向があります。 しかし、多軸ロボットポジショナを採用した最新のアンテナ測定レンジでは、測定タイプとスキャン形状に関してほぼ無制限の再構成が可能です。 このため、それぞれの固有のセットアップとアプリケーションを評価する継続的なニーズが生じています。 この以前は想像もできなかった柔軟性により、安全性、測定品質の向上、測定の不確実性の低減のための新たな機会がもたらされます。 これらの新しいロボットシステムは、高度なプロセッシング技術の実装を可能にする大量の特殊データを取得できます。 モデルベース システム エンジニアリングおよび開発 (MBSE/MBD) アプローチを採用すると、特定のプログラムのテスト開発および検証フェーズに関連する時間、労力、コストを大幅に削減できます。 MBSEツールを使用してテスト構成を最適化し、測定の不確実性を大幅に低減し、測定をシミュレートすることもできます。 このプレゼンテーションでは、新しいデュアル多軸ロボットアンテナ テストシステムの実装中にこれらのエンジニアリング技術がどのように活用されているかの概要を説明します。
Cylindrical Mode Filtered SVSWR LIVE Demonstration:
邦訳: シリンドリカル モード フィルター SVSWR (CMF SVSWR) は、送信アンテナ (通常は低ゲインの全方向性アンテナ) をターンテーブルの端に配置し、シングル カット ベクトル パターン測定を実行することによって測定されます。 各周波数でのターンテーブル角度の関数としてのベクトル S21 はスペクトル領域に変換され、そこでフィルターを適用してチャンバー効果を数学的に除去できます。 SVSWR は、チャンバー内の元のパターンと「クリーン」フィルター処理されたパターンを比較することによって導かれます。 このCMF SVSWR は、EMCチャンバーのクワイエット ゾーンのより包括的な評価を提供し、特別な位置決め治具を使用せずに簡単に測定できます。 デモンストレーションでは、リアルタイムで実行できるプロセッシングを含む測定プロセス全体をお見せします。 この新しい測定技術は、18GHz ～ 40GHz の EMCテストサイト評価のために ANSC C63® 委員会によって開発中の新しい規格草案 ANSI C63.25.3 に向けて検討されています。

CISPR A and ANSC C63® Overview on Site Validation Measurements from 18 GHz to 40 GHz
Testing to FCC requirements at frequencies above 18 GHz has been occurring for many years, extending up to 231 GHz; however, there has never been a test site validation method developed for this frequency range. The assumption has been that sites qualified below 18 GHz were acceptable above that frequency, but this conclusion was not based on data. With the advent of transmitters operating at 25 and 38 GHz and above, site validation has become more critical, and testing in the far-field and within the beamwidth of the measurement antenna becomes more difficult. The goal of the C63.25.3 working group is to develop site validation methods from 18 GHz to 40 GHz to enhance the validity and repeatability of future measurements and to provide validations and correlations for alternative test sites such as compact antenna test ranges (CATRs) and reverberation chambers to help resolve the far-field testing issues.

Recent Advances in EMC Test Site Evaluation Using Advanced Antenna Measurement Techniques
Calibrating antennas and validating test sites are interdependent processes, as they both mandate accurate antenna measurements in their testing environment. Site VSWR, as specified in CISPR 16-1-4 or C63.25, is used as the figure of merit to qualify test site performance from 1 GHz to 18 GHz. In the CISPR method, the standing wave is measured by sampling scalar fields along several linear paths. However, in an effort to simplify the measurement, test data are severely under sampled. Time Domain SVSWR, as specified in C63.25.1 (1-18 GHz), was developed to address the under sampling issues. For above 18 GHz tests, new challenges emerge, such as the need to test more locations in the Quiet Zone (QZ) and to measure the receive antenna beam coverage. Cylindrical Mode Filtered SVSWR developed as a result, which is now under active consideration in the C63.25.3 (18-40 GHz) and CISPR 16 standards. Participants of the seminar will gain a deeper understanding on technical background (the whats and whys) of the evolution of the test methods, and how advanced antenna measurement techniques are used to help to solve the different technical challenges.

Innovative Robotic Antenna Measurements
Traditional antenna test facilities are typically designed with a specific measurement application in mind, and as a result these facilities tend to be comprised of single fixed measurement geometry. However, modern antenna measurement ranges employing multi-axis robotic positioners provide a near limitless degree of re-configurability in terms of measurement types and scan geometries. This drives an ongoing need to evaluate each unique setup and application. This previously unimaginable flexibility offers new opportunities for the improvement of safety, measurement quality and reduction of measurement uncertainties. These new robotic systems are capable of acquiring large amounts of special data allowing for the implementation of advanced post processing techniques. Model Based Systems Engineering and Development (MBSE/MBD) approaches can be employed to dramatically reduce the time, effort and cost associated with the test development and validation phases of a given program. MBSE tools can also be used to optimize test configurations to greatly reduce measurement uncertainties and simulate measurements. This presentation provides an overview of how these engineering techniques are being harnessed during the implementation of a new dual multi-axis robotic antenna test system.
