远程命令从E4434B移植到E4434C是否应该将所有SCSI命令升级到E4438C手册中列出的内容？

您好，我有一个自定义C ++应用程序，通过VISA与GPIB与Agilent E4434B对话。
该应用程序运行良好，但我们不得不从使用E4434B切换到E4438C。
在大多数情况下，转变是无缝的。
但是，我们注意到了行为上的差异，每次调查时，两个仪器之间的SCSI命令似乎有点不同。
两个问题：1）我们是否应该将所有SCSI命令升级到E4438C手册中列出的内容？
2）有谁知道这两个发电机之间的SCSI差异是什么？
谢谢

  Hello,

I have a custom C++ application that talks to an Agilent E4434B through VISA with GPIB.  The application works well however we had to switch from using the E4434B to an E4438C.  For the most part the change over was seamless.  However, we have noticed off differences in behavior and every time I look into it, it seems that the SCSI commands are just a little bit different between the two instruments.   

Two questions:   

1) Should we upgrade all the SCSI commands to what is listed in the E4438C manual?   

2) Does anyone know the what the SCSI differences are between these two generators?

Thank you
