N3300A直流电子负载的编程列表该怎么读取？

嗨，我正在通过Linux-GPIB包和Python从列表编程测量，下面你将看到代码。
当我尝试读取缓冲区时出现问题。
如果我使用'FETC：ARR：VOLT？'，它只是提供瞬时测量，但如果我使用'FETC：CURR：ARR ARRAY1'，电子负载显示：ERR -113，未定义的标题[此设备不允许操作]。
我怎样才能读回与列表中显示的九个点相对应的电压值？
非常感谢提前，问候，Rubénimportgpib从时间导入sleepdef lista（）：self = gpib.find（'eload'）#LISTgpib.write（self，'CURR：MODE LIST'）gpib.write（self，'LIST：

  Hi,

I am programming a measurement from a list through the Linux-GPIB package and Python, below you will see the code. My problem comes when I try to read the buffer. If I use 'FETC:ARR:VOLT?', it just deliver an instantaneus measurement but if I use 'FETC:CURR:ARR ARRAY1' the electronic load shows: ERR -113, Undefined header [operation not allowed for this device]. How could I read back the voltage values corresponding to the nine points showed in the list?

Thanks a lot in advance,
Regards,
Rubén
