'The triggering frequency ranges given here are limited to the -3dB frequency of the oscilloscope vertical system
(mainframe and amplifier
unit) when operating from an internal source .
3 Will not trigger on sine waves at or below 60 Hz when amplitudes are less than 8 divisions internal or 3
volts external .
'The Triggering Frequency Range for DC COUPLING applies to frequencies above 30Hzwhen
operating in the AUTO TRIGGERING MODE .
