Ikalogic has just release TrigBox. As the name implies, it adds Trigger IN/OUT capability to the existing range of ScanaQuad logic analyzers. The way it works is quite simple: A special synchronization signal is exposed to the 5th pin of the USB connector, and a custom (5 wires) USB cable is used to get that sync signal to TrigBox. Adequate circuitry then provides deterministic propagation delays as well as 50 Ohm drive capability on the Trigger OUT line.
TrigBox allows ScanaQuad to sync with any existing instrument. For instance, you can use the ScanaQuad to trigger an oscilloscope on a specific protocol feature. Alternatively, you can use trigger IN feature of TrigBox to let ScanaQuad start capturing signals according to another instrument in your lab.
