Features and Functions Chassis Synchronization and Triggering
The 10 MHz output is synchronous with the internal CLK100 signal.
1
Connect the external instrument’s clock input to the ESM’s front panel SMA
CLOCK OUT
connector.
2
Enable the external clock output by checking its Enable box on the Web
Interface’s Chassis Health page.
Triggering
This section introduces the AXIe chassis’s trigger bus resources and some of the
many ways you may use them. Any AXIe instrument can be triggered:
- internally, based on its own automation or signals from DUT connected
directly to it
-
through an externally applied trigger.
-
through the chassis backplane,
The AXIe chassis allows you to trigger instruments—singly, in groups, or all
instruments in the chassis—from different signal sources.
The diagram below shows how the triggering resources are derived
