Note 1: add 1.5 % for variable gain mode
Note 2: 2 div centerscreen signal with a frequency of 50 kHz, shifted within central 6 div.
Note 3: At 10 MHz; input to deselected channel equivalent to 8 div. or less.
Note 4: PM3092/3094 a t200 MHz; PM3082/3084 at 100 MHz; channels with equal V/div setting;
input to deselected channels equivalent to 6 div.
Note 5: PM3092/3094 at 200 MHz; PM3082/3084 at 100 MHz; channels with equal V/div.
