If all else fails to prevent rf interference from being introduced into the input, external filtering of the device input paths may be required, as shown in Figure 3-7.

如果所有的措施都不能避免RF干扰进入测试输入端，那么就可能需要在设备的输入通路上进行外部滤波，如图3 - 7所示。

Shielding the test leads and the DUT (Figure 3-6) will often reduce interference effects to an acceptable level.

对测试引线和DUT进行屏蔽(图3 - 6)常常能够将这种干扰的影响降低到可以接受的水平。
