8710D缺少TDR功能选项010

我的8710D上的序列号面板显示OPT 010作为配置的一部分包含在内，但缺少TDR菜单选项，固件版本未列出010.（固件标识中包含另一个选项1D5）。
安捷伦科技服务建议我在这个论坛上寻求帮助，因为他们不再支持这种老式设备了。
自从我们最后一台带有TDR的分析仪用完后，需求有所增加。

  The serial number panel on my 8710D shows that OPT 010 is included as part of the configuration, but the TDR menu pick is missing and the firmware revision does not list 010. (another option 1D5 is included in the firmware identification).
Agilent Tech services suggested I ask on this forum for help, since they do not support this vintage equipment any more. The need has increased since our last remaining analyzer with TDR tanked.
