Oops, I didn't have seen!
At the download Section the last version is described as "Version 3.9 Build 4".
You must download the file and install to see the 3.9.4.3

I checked the Reference File, it is OK, thanks.
Please, don't get of your mind the "wishes list".

Thanks for the info.
Is there a time that you are going to upload the 3.9.4.2 version?

I can't load to an exist X-Y Plot a stored reference file (*. ref)

The wrong message is "The file is not in reference file (*.ref) format.

But, I don't think so that I have wrong procedure about it.
The steps that I follow are:
- right click on X-Y Plot and -> X-Y Plot Reference...
- click on ...

Thanks for the answer.
1) Yes, it is know, but it needs you adapt all the axis, X-Y Plots, e.t.c every time you want to change something... it is not optimum that!
Have in mind that the Alias text, doesn't accept all the characters, except comma (,), the phrase "THD+N(%)_Ch.A" doesn't accepted-> it ...

Yeap!
Thank you very much for the supporting.

Here is the .dtp file

Thank you a lot for all these information.

I spent time to experiments to various combinations btw ADC-DAC Output and Peak Level Check.
The best that I achieved was the first capture.
Then I followed a simple method, like case-2.
I make 4 .psf files at the levels of -20/0/+20/+30 dBV with 131K IMD ...

...In conclusion, what changes must to done, to have a measure from -100dB....
- OK, I found it, I changed the x3 to 0.0002V and I have an almost -97.7dB low end range capturing...now I can modified depends my needs this parameter.

The new capture that I have included is with:
- Intra-Frame Proc ...

Many thanks for the help.

At the case-1

1) yes, it is very slow procedure, I removed the Intra_Frame_Procedure (but I think that some kind of average is needed for better normalized data) and at the steps 10&11 (SIO), I changed the Duration to 1s
I think the measuring from a -153dB level, it is ...

Many times we need more divisions in dB Y-scale at the Spectrum Analyzer.
At this time there is 150dB and then jumps to 200dB.
Perhaps, more divisions there will be fine.
