A Quick Tour
You must provide a trigger input signal
Because high-speed oscilloscopes are not capable of triggering directly on a
test signal, you must first connect an external timing reference signal to the
front-panel Trigger input connector. This input allows the Infiniium DCA to
synchonize to the input signal. Clock recovery modules (for example, the
83496B) are available to recover the clock from the test signal.
You can select free-run triggering when an external trigger is unavailable,
however, you will only be able to view the waveform for amplitude information
only without any timing information. This is an easy way to examine the ampli-
tude of a signal.
