Chassis Synchronization and Triggering
The Keysight AXIe chassis provides a rich set of signaling (triggering and timing)
options. These allow you to achieve time-aligned operation of multiple
instruments installed in a single chassis or MultiFrame (interconnected AXIe
chassis system).
An example of time aligned operation would be starting and stopping some
aspect of a test running on multiple instruments in the chassis. The time
alignment of these operations can be:
-
Synchronous
: A single event (trigger signal or sync signal), initiated by an
external trigger, flag, or other signal transition, triggers one or more
instruments simultaneously.
-
Asynchronous:
Instruments operate independently, with their resulting data
to be time-aligned post-collection in your analysis software. This requires the
data to be referenced to a common clock source.
Moreover, there is capability to group instruments and perform such operations
on several independent groups simultaneously. For example, instrument group A
can be triggered from a 100MHz clock and instrument group B can receive an
external trigger from an event transition in the test environment, while receiving
the same clock signal to synchronize the two groups.
Although the triggering and timing options can be inter-operated, it is easiest to
understand them using distinct Clock Bus and Trigger Bus diagrams, each
providing ESM front panel and backplane signal connections.
MultiFrame operation is described in
on page 89. For
this chapter, ‘instruments in the chassis’ includes all instrument modules in the
single chassis or MultiFrame. If you are using only a single chassis, the
MultiFrame references are inapplicable.
Some AXIe test system software applications, such as the Keysight AXIe Based
Logic Analyzer Software and modules, sets and uses specific trigger lines in the
AXIe chassis. Do not use the AXIe chassis Soft Front Panel (SFP) software or the
AXIe chassis web interface to set or reroute any of the AXIe chassis trigger lines.
Rerouting any of the trigger lines may cause the application software to not
function correctly.
