8590A无法执行校准

我有一个8590A，它没有20-db衰减器平坦度或平坦度校准数据的校准数。
我只用零手动输入这个，以便正确显示采集。
但是现在我无法执行校准，因为它没有报告校准信号。
查看Artekmedia从“生成新校准数据”下载的手册，“本章的这一部分在随附的变更单中提供。”
不幸的是，我没有这个更改表，也无法在任何地方找到它。
有没有人碰巧有这个变更表或者可以告诉我如何生成适当的衰减器和平坦度校准？
希望输入正确的校准数据可以正确检测校准信号。
我已将其连接到示波器，因此生成了校准信号。
谢谢！

  I have an 8590A and it didn't have the calibration numbers in for the 20-db attenuator flatness or the flatness calibration data.  I manually entered this with just zeros to get the acquisition to display properly.  However now I am not able to perform calibration as it reports no calibration signal.   

Looking through the manual downloaded from Artekmedia under "Generating New Calibration Data" that "This section of this chapter is supplied in the accompanying change sheet."  Unfortunately I don't have this change sheet nor am I able to find it anywhere.  By any chance does anyone happen to have this change sheet or could tell me how to generate the proper attenuator and flatness calibrations?   

Hopefully entering proper calibration data would allow it to properly detect the calibration signal.  I have connected it to my oscilloscope so there is a calibration signal being generated.

Thanks!
