Triggering the Oscilloscope 4
6000 Series Oscilloscope User’s Guide 139
3 Select the trigger source.
You can select analog channel 1 or 2, Ext, or Line as the
trigger source on any Agilent 6000 Series oscilloscope. The
trigger source can also be set to channel 3 and 4 on the
4-channel oscilloscopes, or digital channels D15 through D0
on the mixed-signal oscilloscopes. You can choose a channel
that is turned off (not displayed) as the source for the edge
trigger.
The selected trigger source is indicated in the upper-right
corner of the display next to the slope symbol:
1
through
4
= analog channels
D0 through D15 = digital channels
E = External trigger
L = Line trigger
Trigger level adjustment
You can adjust the trigger level for a selected analog channel by
turning the Trigger Level knob. The position of the trigger level
for the analog channel is indicated by the trigger level icon
(if
the analog channel is on) at the far left side of the display when
DC coupling is selected. The value of the analog channel trigger
level is displayed in the upper-right corner of the display.
The trigger level for a selected digital channel is set using the
threshold menu in the Digital Channel Menu. Press the
D15 Thru
D0 key on the front panel, then press the Thresholds softkey to
N O T E
Alternating edge mode is useful when you want to trigger on both edges of
a clock (for example, DDR signals). Either edge mode is useful when you
want to trigger on any activity of a selected source. All modes operate up
to the bandwidth of the oscilloscope except Either edge mode, which has a
limitation. Either edge mode will trigger on Constant Wave signals up to
100 MHz, but can trigger on isolated pulses down to 1/(2*oscilloscope's
bandwidth).
