ANOMALY
The Anomaly indicator can be off, red, or yellow. This indicator will turn red if an anomaly (B1,
B2, REI-L, B3, FAS, REI-P, or payload error) is detected. It will flash red if an anomaly is
detected intermittently.
A yellow history indicator signifies that an Anomaly has been detected since the most recent test
started, but is not currently detected.
The Anomaly indicator will turn off when a new test is started.
Rx Event OUT
The Rx Event Output is user activated and provides an active HIGH for each alarm or error
condition generated. The output will provide a single pulse for each frame containing errors. It
can be used as a means of triggering an oscilloscope or other test equipment. The output has an
SMA connector and requires 50 termination for signal integrity.
Rx Data IN
The Rx Data Input provides signal interconnection between the module cards. This input must
be connected to the Rx DATA OUT connection found on the Optics card of the OTS9100
module using the coax cable and DC block provided.
Rx Clock OUT
The Rx Clock Output provides signal interconnection between the module cards. This output
must be connected to the Rx Clock Input found on the Clock Trigger card of the OTS9100
module using the coax cable provided.
