DSO Quad suggestion and bugs.

  1. there is signal once at second by duration 500 mkS in mode “auto” its not possible seize, in mode “norm”, only with unrolling before 100mkS if expose less for instance 50 to consider in detail not possible seize. in mode “singl” seizes, but change duration of the unrolling is not got, numerals are changed but real does not change

  2. if unrolling slow but frequency high that frequency are defined wrong

  3. 100kHz shows 100Hz, 1MHz shows 1kHz
