In the EXT+10 mode, the external trigger signal is attenuated by a factor
of 10.
When the TIME/DIV switch is in the X DEFL position, the BNC socket is
connected to the horizontal amplifier.
A and B depressed simultaneously.
Internal triggering signal is derived from both channels A and B.
EXT and EXT+10 depressed simultaneously.
Internal triggering derived from the line (mains) voltage. Ineffective when
the instrument is battery-powered.
Continuously-variable control of the delay time, operating in conjunction
with the TIME/DIV controls of the MTB.
Continuously-variable control for selecting the trigger level at which the
DTB starts.
This control incorporates a push-pull switch that enables choice of
triggering on the positive or negative-going edge of the input signal.
Time coefficient control of the DTB, ranging from 0.1 ps/DIV to
0.1 ms/DIV in a 1-2-5 sequence.
Continuously-variable control of the DTB coefficients.
The time coefficient selected is calibrated in the CAL position.
Trigger source switch and starting point selection of the DTB.
Internal trigger signal derived from channel A.
Internal trigger signal derived from channel B.
Triggering from an external signal connected to the adjacent 1 MQ-
20 pF BNC socket.
Internal triggering signal derived from the MTB to start the DTB imme-
diately after the selected delay time.
A and B depressed simultaneously.
Internal triggering signal derived from both channels.
