Chassis Synchronization and Triggering Features and Functions
In the above example, TRIG 0 is enabled as an output, and will trigger when
slot 1 sends a STRIG signal. TRIG 2 is also enabled, and will trigger when an
external SMA trigger is applied.
STRIG
The STRIG signal is a Bidirectional Low Voltage Differential Signaling (BLVDS)
star trigger with the following characteristics:
–
Point-to-point and bidirectional between the ESM (logical slot 1) and
instrument slots (physical slots 1 through
n )
– Slot terminated with 100
W
differential and 50
W
series (optional)
– All STRIG lines are trace length matched to 0.025")
Use When:
The STRIG bus’s trace matched lines ensure the lowest skew when
synchronously triggering multiple modules.
