Features and Functions Chassis Synchronization and Triggering
To use a STRIG line as an output:
1
Using the chassis Web Interface, on the
Trigger Routing
page, check an
Output Enable box to enable any individual slot AXIe Star Trigger line as an
output signal.
2
From the Input Signal drop down list, select an input signal for each
output-enabled AXIe Star Trigger output(s).
In the example shown above, STRIG output is enabled for slots 1 through 3,
and will simultaneously trigger these three STRIG lines when an input signal is
received from any instrument on the TRIG 0 bus.
SYNC
The
SYNC
and
CLK100
signals are a Low Voltage Differential Signaling (LVDS)
star trigger and a star clock. SYNC provides an LVDS trigger signal, output at the
next rising edge of CLK100 after the source trigger is received. The SYNC and
CLK100 lines use identical fan out buffers and are trace length matched to 0.25”
to operate as a pair, with the following characteristics:
–
Point-to-point between the ESM (logical slot 1) and instrument slots
(physical slots 1 through
n )
– Slot terminated with 100
