Trigger Specification
Asynchronous Pattern: Trigger on an asynchronous pattern less than or greater
than a specified duration. The pattern is the logical AND of a specified low, high,
or don't care for each assigned channel. If the pattern is valid but the duration is
invalid, there is a 20 ns reset time before the instrument will look for patterns again.
Greater Than Duration: Minimum duration is 30 ns to
10
ms with
10
ns or
0.01%
resolution, whichever is greater. Accuracy is + 0 ns to -20 ns. Trigger occurs at
pattern + duration.
Less Than Duration: Maximum duration is 40 ns to
10
ms with
10
ns or
0.01%
resolution, whichever is greater. Pattern must be valid for at least 20 ns. Accuracy
is + 20 ns to -0 ns. Trigger occurs at the end of the pattern.
Glitch/Edge Triggering: Trigger on a glitch or edge following a valid duration of
an asynchronous pattern while the pattern is still present. Edge can be specified as
rising, falling, or either. Less than duration forces glitch and edge triggering off.
Measurement
Autoscale (Timing Analyzer Only)
and Display
Functions
Autoscale searches for and displays channels with activity on the pods assigned to
the timing analyzer.
General Information
I-12
Acquisition Specifications
Arming: Each analyzer can be armed by the run key, the other analyzer, the
oscilloscope, or the external trigger in port.
Trace Mode: Single mode acquires data once per trace specification. Repetitive
mode repeats single mode acquisitions until stop is pressed or until the time
interval between two specified patterns is less than or greater than a specified
value, or within or not within a specified range. There is only one trace mode when
two analyzers are on.
Labels
Channels may be grouped together and given up to a six character name. Up to 20
labels in each analyzer may be assigned with up to
32
channels per label. The
primary use is for naming groups of channels such as address, data, and control
busses.
