Features and Functions Chassis Synchronization and Triggering
TRIGGER OUT
The
TRIGGER OUT
signal (also known as
SMA TRIGGER OUT
) is available on
the ESM front panel
TRIGGER OUT
SMA
connector with the following
characteristics:
–
3.3V CMOS drive, 100 mV minimum swing
–
50
W
output termination
Use When:
TRIGGER OUT
allows you to extend the trigger bus to instruments
outside the chassis system or which require an external input.
To use SMA TRIGGER OUT as an Output Signal:
1
Connect a cable from the chassis
SMA
TRIGGER OUT
connector to the
instrument you wish to trigger.
2
Using the chassis Web Interface, on the
Trigger Routing
page, check the
Output Enable box to enable the
SMA
TRIGGER OUT
signal as an output
signal.
3
From the
Input Signal
drop down list, select an input signal to connect to the
output-enabled
SMA
TRIGGER OUT
output signal.
4
Under Conditions, you can select whether or not an 80-160 ns pulse is
generated (always on the rising edge of the signal) and whether the signal is
inverted just prior to the
SMA
TRIGGER OUT
connector. The default is no pulse
(“None”) and Passthrough (no inversion).
In the above example, the
SMA
TRIGGER OUT
output signal is enabled and it
will output an inverted signal when a STRIG signal is received from slot 1.
MultiFrame Flags
Four BLVDS flags are provided on the MultiFrame cables. These flags can be
distributed among any applications in a MultiFrame chassis that use
asynchronous flagging.
A flag is an asynchronous pulse, which any instrument in any chassis can
generate in response to a signal transition or program command.
