BNC Connectors Ext. In and Ext. Out
These BNC connectors allow the Analyzer to transmit or receive external signals.
External signaling, in turn, can serve two functions:
• Linking of Analyzers: On dual Analyzer systems, the BNC connectors are used to
create a loop for transmitting clocking information and commands between the
Analyzers. This linking allows the two Analyzers to function as a single, logical
Analyzer.
• Triggering: The Ext. In can receive a signal from another device and use that
signal to trigger the end of the recording. Conversely, the Ext. Out connector can be
used to send an output signal from the Analyzer to another device.
The Ext. In and Ext. Out connectors have the same function as the 25 pin RS-232
connector - i.e., they channel input and output signals but do not support the use of a
Breakout Board.
VHDCI Sync In and Sync Out Connectors
These connectors allow multiple PETracer Summit or Summit T2-16 analyzers to send
synchronization and control messages to one another.
