请问我的E8257D是否有可能在绝对功率下上下运行振幅斜坡

我用新的E8257D代替83600系列合成器进行增益压缩测试。用83600系列我可以设置CW频率幅度斜坡扫描，比如每次扫描10分贝，然后调整斜坡的整体幅度
使用RF放大器调整。
当我在83600系列上执行此操作时，整个斜坡的幅度会上下移动。我似乎无法使用E8257D执行此操作。
当我设置斜坡然后尝试调整斜坡的整体幅度时，斜坡关闭。
是否有可能在绝对功率下上下运行振幅斜坡，而它仍然像83600系列一样可以斜坡上升，如果是这样，怎么样？
我不想改变斜坡，只是线性地改变斜坡的整个幅度。谢谢。

  I'm substituting a new E8257D in place of an 83600 series synth for a gain compression test.

With the 83600 series I can set up a CW freq amplitude ramp sweep, say 10 db per sweep, and then adjust the overall amplitude of the ramp with the RF ampl adjustment. When i do this on the 83600 series the whole ramp moves up and down in amplitude.

I don't seem able to do this with the E8257D. When i set up the ramp and then try to adjust the overall amplitude of the ramp the ramp is turned off.

Is it possible to run the amplitude ramp up and down in absolulte power while its still ramping like I can with the 83600 series, and if so, how?  i don't want to change the ramp, just the entire amplitude of the ramp linearly.

thanks.
