EXT
—This BNC socket is the external trigger signal input.
In dual X-Y mode, signals at this input are used for the X deflection.
Pressing the TRIG. SOURCE (29) pushbutton until the information of
“EXT, slope, coupling” is shown up in the readout and the TRIG.
SOURCE “EXT” LED is lighted, switches the input on.
The outer (ground) connection is galvanically connected to the
instrument ground and consequently to the safety earth contact of the
line/mains plug.
The maximum input voltages of the instrument input terminals and probe
input terminals are listed in the section of 3-6.Withstanding voltage of
Input terminals”. Do not apply voltage higher than the limit.
