marconi 2955a test set

hello,

I'm new to the marconi test set 2955A. I want to know if I can disable the autotune function. It seems to be present even when you type a tx frequency in directly.

I am trying to capture, through a PC, low bit rate epirb data but there are two carriers simultaneously present and I think one carrier is saturating the front end of the test set by autotune to strongest carrier. I'm not interested in the offset, as stated.

Is this possible.
