當觀察脈沖上升時間低于 100 納秒、射頻電流高于幾兆赫茲或使用長電纜時，建議在示波器上端接 50 歐姆的電流監視器輸出電纜，以防止駐波或電纜填充時間影響。采用這種端接時，輸出電壓約為未端接值的一半，具體取決于端接電阻的精度和電纜的衰減。

When viewing pulse rise times below 100 nanoseconds, RF currents above a few megahertz, or when using long cables, it is advisable to terminate the current monitor output cable at the oscilloscope with 50 ohms to prevent standing waves or cable fill-time effects. With this termination the output voltage will be approximately half the unterminated value, subject to the accuracy of the termination resistance, and the attenuation of the cable.

由于高頻電流在電纜屏蔽層的外部流動，快速上升的脈沖會產生觀察到的雜散振鈴。可以通過將電纜穿過一個或多個磁芯來增加屏蔽層的電感來抑制該電流。使用四根內徑約為 1 英寸、外徑約為 2 英寸、厚度為 1/2 英寸的鐵氧體磁芯進行三匝，獲得了良好的結果。

Fast-rising pulses can produce spurious observed ringing due to high frequency current flowing on the outside of the cable shield. This current can be suppressed by increasing the inductance of the shield run by threading the cable through one or more magnetic cores. Good results have been obtained using three turns through four ferrite cores of about one inch inside diameter, two inch outside diameter and 1/2 inch thickness.

使用外部端接時，型號 2877、4100、2100、3100、150、410、411、110、110A 和 1010 將表現出更低的壓降和更高的電流時間積。

With external termination, models 2877, 4100, 2100, 3100, 150, 410, 411, 110, 110A, and 1010 will exhibit lower droop and increased current time product.
