Relative Code Domain Error (E4406A)

Hi,

I have recently been asked to conduct relative code domain error measurements using a E4406A.

There is no specific command on the E4406A to allow relative code domain error measurements but the RCDE can be calculated 10 log (Absolute CodeEVM)/ (Absolute Code Domain Power).

Since it is possible to calculate Code Domain Power, I am assuming that the absolute Code Domain Power is referiing to the absolute value of the CDP e.g. abs(-66dBm) = 66dBm

However I am unsure how to find Absolute CodeEVM, it must be possible since it is necessary in order to determine PCDE.

Can anyone help with this?

Rgds,
Sean
