Use the Normal 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.

To perform a Single Sequence acquisition, push the Single button.

Source Options.

Source option Details

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 +1.6 V to -1.6 V

Ext/5 Same as Ext option, but attenuates the signal by a factor of five, and

allows a trigger level range of +8 V to -8 V; this extends the trigger level

range

AC Line

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.

You can use the AC Line when you need to analyze signals related to the

frequency of the power line, such as lighting equipment and power supply

devices; the oscilloscope automatically generates the trigger, sets the

Trigger Coupling to DC, and sets the Trigger Level to zero volts.

NOTE. To view an Ext, Ext/5, or AC Line trigger signal, push and hold down the

Trigger Menu button for more than 1.5 seconds to enable trigger view.

Coupling. Coupling allows you to filter the trigger signal used to trigger an

acquisition.

Option Details

DC Passes all components of the signal

Noise Reject Adds hysteresis to the trigger circuitry; this reduces sensitivity which

reduces the chance of falsely triggering on noise

HF Reject Attenuates the high-frequency components above 80 kHz

LF Reject Blocks the DC component and attenuates the low-frequency components

below 300 kHz

AC Blocks DC components and attenuates signals below 10 Hz

NOTE. Trigger coupling affects only the signal passed to the trigger system. It

does not affect the bandwidth or coupling of the signal displayed on the screen.

Available only when you select the Edge trigger type.
