Hello to all! I want to share information about the device I purchased, Anritsu MS8607A. This is a model for the domestic Japanese market, but it still turned out to be in Russia.
This device is similar to MT8801 in terms of functionality and capabilities, acquired for the function of a spectrum analyzer, which it successfully performs.Unfortunately, I do not know English and I have to use a google translator. If you have questions, I will try to answer.

P.S.: special thanks to
