All frequency components of the input signal are
coupled to the vertical. Input resistance is 1 Mil to
ground.
All frequency components of the input signal are
coupled to the vertical, with the input terminated by
50 II to ground. If excessive signal is applied to
either the CH 1 or the CH 2 input connector while
50 II DC input coupling is selected, input coupling will
revert to 1 Mil GND and a CRT readout will indicate
the overloaded condition. Changing the input
coupling of the affected channel removes the
overload message.
Conduct external signals to the Channel 1 and Channel
2 vertical inputs. A signal applied to the CH 1 OR X
connector provides the horizontal deflection for an X-Y
display. Each connector includes a coding-ring contact
for Tektronix-coded probes.
