Different Spectrum Analyser with different RSP's?

Hi Steve,
First of all I confirm that low frequency performance down to 100 KHz is is excellent, as demonstrated by the enclosed pics., which I have already uploaded here:

The reason why I upload them again here is to allow comparison between noise scans taken with the Spectrum Analyser software with the RSP-1A and the RSPduo. The filter is the same, the settings are the same, the noise generator is the sane, only the RSP is different and there are significant differences in the display, which would seem to be caused only by different characteristics in the RSp's. Below are scans with RSP-1A. In the next post those taken with RSPduo.
