54615B触发控制失败

在过去的几天里，我一直在尝试为HP54615B示波器找到替换键盘P  N 54600-66052。
显然，安捷伦在2006年放弃了对该项目的支持，不再需要更换零件。
我已将示波器故障范围缩小到单个机械旋转编码器，用于通过前面板设置触发电平。
该部件的后盖上印有9707和1-2-36。
它是一个3针，2个正交通道，每转9个脉冲，无制动器，连续旋转编码器。
是否可以找到该部件的原始制造商的部件号或功能替换件？
将这个范围隐藏在这样一个小问题上是一种耻辱。
谢谢你提供的所有帮助。

  For the past few days I’ve been trying to locate a replacement keyboard PN 54600-66052 for the HP54615B oscilloscope. Evidently Agilent dropped the support for this item in 2006 and no longer has replacement parts.  

I have narrowed the scope’s failure down to a single mechanical rotary encoder that is used for setting the trigger level via the front panel. The part has 9707 and 1-2-36 stamped on its rear cover. It is a 3-pin, 2 quadrature channel, 9 pulse per rotation, no detent, continuously rotating encoder. Is it possible to find the original manufacturer’s part number for this part or a functional replacement? It's a shame to mothball this scope over such a minor issue.

Thanks for any help you can give.
