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 -

1.2 V to +1.2 V.

EXT/5

Same as Ext option, but attenuates the signal by a

factor of five, and allows a trigger level range of

+6 V to -6 V. 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.

Mode

Auto

Use this mode to let the acquisition free-run in

the absence of a valid trigger. This mode scans

waveform at 100 ms/div or slower time base

settings.

Normal

Use this mode when you want to see only valid

triggered waveforms; when you use this mode,

the oscilloscope does not display a waveform

until after the first trigger.

Single

When you want the oscilloscope to acquire a

single capture of a waveform, press the

“SINGLE” button.

Set up

Enter the “Trigger Setup Menu” (See below
table).
