Step 4 Press Record > Start button to arm the analyzer. The analyzer
will indicate it is waiting for a trigger. Any edge detected on the
Trigger In signal will stop the recording and fill the buffer on the
analyzer.
Note:: Voltage required on the edge condition is 0 to.8V low, 2.0V to 3.3V high. 40nS
is the approximate detection threshold for the BNC Trigger In feature.
Note:: There is also a trigger indicator on the analyzer front panel that will indicate
when the trigger condition has been detected by the analyzer.
Breakout Board Trigger In / Out
The Breakout Board connects via a 25 pin
serial interface cable to the Data In/Out
connector located on the rear of the analyzer
unit. Each signaling pin is isolated by a 100
Ω
series resistor and a buffer inside the Analyzer
unit. Six ground pins and one 5-volt pin are
provided.
