Note 1: Add 1.5% for variable gain mode.
Note 2: 2 division center screen signal with a frequency of 50 kHz, shifted within central 6 divisions.
Note 3: At 10 MHz; input to deselected channel equivalent to 8 divisions or less.
Note 4: Channels with equal V/div; input to deselected channels equivalent to 6 divisions.
Note 5: Channels with equal V/division settings; input to either channel 6 div. PM3390B/94B; max.
input amplitude 3Vpp
Note 6: Between any two input channels at same attenuator setting; VAR of V/div setting adjusted
for best CMRR; measured with max. 8 div.
