Edge
With Edge highlighted, the rising or falling edge
of the input signal is used for the trigger.
Source
CH1
CH2
Triggers on a channel whether or not the
waveform is displayed.
EXT
Does not display the trigger signal; the Ext
option uses the signal connected to the EXT TRIG
front-panel BNC and allows a trigger level range
of -1.2V to +1.2V.
EXT/5
Same as Ext option, but attenuates the signal by
a factor of five, and allows a trigger level range
of +6V to -6V.This extends the trigger level
range.
AC Line
This selection uses a signal derived from the
power line as the trigger source; trigger coupling
is set to DC and the trigger level to 0 volts.
Slope
Trigger on Rising edge of the trigger signal.
Trigger on Falling edge of the trigger signal.
Trigger on Rising edge and Falling edge of the
trigger signal.
