如何让8560a/8560e跟踪发生器更换?

有没有人有一个线索如何让一个8560a / 8560e跟踪发生器工作时，你用一个好的跟踪发生器替换一个坏的？
似乎我的a14必须以某种方式匹配跟踪gen或者我没有在屏幕上显示任何输出信号和错误901跟踪gen freq限制和跟踪gen unlevel错误。
我检查了前面板跟踪发生器的输出，它应该是-10 db，并在放入单独的spec分析器时进行扫描。
所以我很难过。
从服务手册中输入新的tg时，没有关于任何类型的重新调整的任何信息。
完全没用。
我想知道是否有一个类似的程序来重新调整yto ????
任何猜测？
任何一个成功地在这两个模型中的一个中交换了一个tg？
我尝试了5个跟踪gens，每个跟踪gens一样。
没有！
但当我把坏的一个放回来时，我再次发出信号，它就像它应该的那样不平坦。

  does anyone have a clue how to get an  8560a / 8560e tracking generator to work when you replace a bad one with a good one? it seems like my a14 has to match the tracking gen in some way or i get no output signal displayed on the screen whatsoever and error 901 tracking gen freq limit and tracking gen unlevel error as well. I checkd the output of the tracking gen from front panel and its at -10 db as it should be and sweeps when put into a separate spec analyzer. so im stumped. there is no info whatsoever about any kind of realignment when putting a new tg in , from the service manual. completely useless. im wondering if there is a similar procedure to realigning the yto???? any guesses? any one successfully swapped a tg in one of these 2 models? i tried 5 tracking gens and its the same with each one. nothing!  but when I put the bad one back in i get signal again its just not flat like it should be.
