8560a无法重新调整yto因为跟踪发生器而没有外部混音器

大家好，它来自测试仪器。
我试图在我的各种8560a单位中重新调整我的yto，因为如果安装了跟踪代码，8560a服务指南中的说明是不正确的。
没有办法选择ext mixer，并且辅助控制菜单中没有外部混音器软键。
一旦安装了跟踪gen，它就会被删除。
那么如何重新调整或检查我的yto？
我唯一能想到的就是以某种方式对单元进行解编程，使其认为没有安装跟踪代。
然后直接将y输出从yto输入到我的计数器？
或者将它路由到正常路由的路由器？
我很难过请有人告诉我如何做到这一点，我也想知道分析仪是如何知道安装了跟踪代码的。
是一个软件程序还是只是在向9系列添加opts时的跳线？
谢谢 ！

Hi everyone its paul from test cal instruments. I have tried to realign my yto in my various 8560a units and cant because the instruc tions in the 8560a service guide are incorrect if a tracking gen is installed. there is no way to select ext mixer unpre, and there is no external mixer softkey in the aux control menu. it is removed once tracking gen is installed. so how do I realign or check my yto? the only thing i can think of is somehow deprogramming the unit to making it think there is no tracking gen installed on it. and then taking the lo output directly from the yto feed to my counter? or routing it into the lo dist amp as it would have been normally routed? im stumped can someone please tell me how to do this and also I would like to know how the analyzer knows there is a tracking gen installed. is that a software program or just a jumper like when adding opts to the 9 series? thanks !
