A differential probe is used to look at signals that are referenced to each other instead of earth ground and to look at small signals in the presence of large DC offsets or other common mode signals such as power line noise. A differential probe can be used to make single-ended measurements by using its negative input as a ground reference contact and there are several advantages to using a differential probe to make single ended measurement action. Differential probes are especially popular for measuring high-frequency signals or signals where neither are referenced to ground.
The global market for Differential Probe is estimated to increase from US$ 50 million in 2024 to reach US$ 68 million by 2031, exhibiting a CAGR of 4.7% during 2025-2031.

| ※参考情報 差動プローブは、電子回路や信号処理の分野において、特に高周波信号の測定を行う際に利用される重要な測定器具です。差動プローブは、主に二つの信号の差を測定するために設計されており、一般的な単端プローブ(シングルエンドプローブ)とは異なる特性を持っています。ここでは、差動プローブの概念や特徴、種類、用途、関連技術について詳しく説明します。 差動プローブの定義と特徴 差動プローブは、2つの信号点間の電圧差を測定することができるデバイスです。これにより、共通モード雑音や接地の問題を無視した、より正確かつ信頼性の高い測定が可能になります。信号測定の精度を高め、余分なノイズを低減するための設計がされています。具体的には、差動プローブは入力端子が2つあり、一方の端子が「正」入力、もう一方が「負」入力となっています。プローブ内部で信号は差動アンプによって処理され、二つの入力信号の差が出力信号として得られます。 特性としては、広帯域幅、高インピーダンス、低入力キャパシタンスといった性能が挙げられます。これにより、高速信号の測定が容易になり、チャンネル間の相互干渉を最小限に抑えることが可能です。また、差動プローブは通常、特定の回路構成に応じてキャリブレーションされているため、正確な測定結果が得られます。 差動プローブの種類 差動プローブには主にアナログ差動プローブとデジタル差動プローブの2種類があります。アナログ差動プローブは、高周波信号に対する応答性が高く、リアルタイムに信号を測定する能力があります。一方、デジタル差動プローブは、デジタルオシロスコープと組み合わせて使用されることが多く、サンプリングデータとして信号を取得します。 さらに、選択性の高い差動プローブも存在し、特定の周波数範囲での測定性能を最適化しています。これにより、特定のアプリケーションにおいて、ノイズを抑えた測定が可能になるのです。 用途 差動プローブの用途は多岐にわたります。主な用途としては、デジタル回路やアナログ回路の測定、RF信号の分析、通信機器のテスト、電源回路のチェックなどが挙げられます。例えば、デジタルシステムでは、多くの場合、相互に干渉する信号が存在しますが、差動プローブを使用することでこのようなノイズの影響を受けることなく、正確な信号測定が行えます。 また、差動プローブは高い誘導電圧を持つ信号や、接地異常のある環境においても安心して使用できるため、研究開発や製品検査においても広く利用されています。特に、電子機器の安全性や信頼性をテストする際には欠かせない測定器具となっています。 関連技術 差動プローブに関連する技術としては、まず信号処理技術が挙げられます。信号処理アルゴリズムは、差動プローブで取得したデータをより理解しやすくするために重要です。このプロセスには、フィルタリングや周波数解析が含まれ、雑音を除去したり、特定の周波数成分を強調したりします。 さらに、差動プローブはオシロスコープと組み合わせて使われることが一般的ですが、これによりデジタル信号の可視化や解析が容易になります。特に、リアルタイムオシロスコープ技術が進化することで、瞬時に信号の変化を捉えることができ、設計者やエンジニアにとって非常に有益です。 また、近年の技術進化に伴い、差動プローブのポータブル化や、さらなる精度向上が図られています。特に、無線通信やIoT技術の発展に伴い、実験室外での信号測定が増える中で、可搬性のある差動プローブの需要が高まっています。 最後に、差動プローブに関連する重要な研究テーマとしては、製造プロセスや材料開発、ノイズ最小化技術が挙げられます。新しい材料の開発や製造技術の革新により、より高精度で高帯域幅な差動プローブの実現が期待されています。 このように、差動プローブは高精度な信号測定を可能にするための重要なツールであり、多様な分野での応用が進んでいます。信号測定の際にはその特性を理解し、適切な使用法を選ぶことが必要です。今後も電子工学の進展と共に、差動プローブの重要性は増していくと考えられます。 |
