Triggering the Oscilloscope

To use Edge triggering

To use Edge triggering

The Edge trigger type identifies a trigger by looking for a specified slope and voltage level on a waveform. You can define the trigger source and rising or falling edge in this menu. The trigger type, source, and level is displayed in the upper-right corner of the display.

1Press the Edge key in the Trigger section of the front panel to display the Edge trigger menu.

2Press the slope softkey ( ) and select either rising edge or falling edge. This determines whether the trigger will occur on the rising edge or the falling edge of the input signal.

Slope Selects rising edge ( ) or falling edge ( ) for the selected trigger source. The selected slope is displayed in the upper-right corner of the display.

3Select 1, 2, Ext, or Line as the trigger source.

The trigger source can also be set to channel 3 and 4 on the 4-channel oscilloscope, or can be set to digital channels D15 through D0 on the mixed-signal oscilloscope. You can choose a channel that is turned off as the source for the edge trigger. The selected trigger source is displayed in the upper-right corner of the display next to the slope symbol:

1 through 4 = analog channels

D15 through D0 = digital channels

E = External trigger

L = Line trigger
