Action Comment
Check that the second row shows the type and
polarity of trigger edge required. If not, highlight
row two and push to change the settings.
Default is TTL, Negative.
Push or to highlight the Triggers per arm
(Count) setting and enter 4096.
The Trigger subsystem Arm 2 and Arm1 layer
trigger events are automatically satisfied since
they are set to their defaults, Immediate. The
Trigger layer accepts 4096 external triggers
before it returns to the Idle state.
Set Delay to zero.
Setting Delay to zero minimizes the delay
(latency) between the trigger edge and start of the
acquisition. This is important if the digitized data
is used to determine the phase-angle relationship
of the signal to the trigger.
Set Holdoff to zero.
Holdoff prevents Trigger Too Fast errors if the
Trigger subsystem is free running without other
delays. In this case, timing is controlled by an
external signal so Holdoff should be set to zero.
Push once or twice Returns to the Digitize function
Connect the trigger signal to the BNC connector
on the rear panel.
The system is now ready to begin data capture
Push to start the acquisition.
The Product captures 4,096 readings and saves
data to memory.
When the progress bar has turned from white to green the data has been
captured and can be analyzed using or exported to an external device for
analysis elsewhere. Push to access data transfer options. See the
screen in Digitizing Examples.
