直通不需要为零长度。
从理论上讲，没有限制，但在实践中，我认为我推荐的最大几英寸。
通常，直通与DUT的长度相似。
在AFR中，有一个条目用于输入通过长度的值或使用打开或短路或DUT作为自我确定通过长度的参考。

The thru doesn't need to be zero length. In theory there is no limit, but in practice I would guess a few inches is most I'd recommend. Usually the thru is similar in length to the DUT. In AFR, there is an entry to enter the value of the thru length or use opens or shorts or the DUT as a reference to self-determine the thru length.
