I have got ready a simple Excel spreadsheet to upload the S21 and S31 exports from the KC901V/S and calculate Common Mode Rejection Ratio and some other imbalance calculations for any balun.
Please, have a try and let me know.

@WTEK Hi Daniel, from some days I am measurement S21 from a 4:1 Guanella balun. Most values are under normal range but one of them I can´t get it correct.
The S21 loss from input to output, it is always showing around 6dB loss when it should be around 0dB !!
Now reading your discover about the insuficient return loss of RF IN... it could be the cause of mine headache !!
Unfortunatelly, I don´t have any other test equipment to check that.
WuXiao, please, take some action on this.
