The 556 is a true dual-beam scope and none of the signal paths is shared between the two beams. Electrically speaking, the power supply and the calibrator are the only parts that are common to both beams. Apart from the power supply, the 556 has almost complete left-right symmetry, corresponding to top and bottom beams. Although the beams can be operated completely independently, the 556 provides many options for routing signals between the vertical plug-ins, triggers, sweeps, horizontal amplifiers, and vertical amplifiers. For example, a common use for a dual-beam scope is to view two simultaneous single-shot events, both sweeps being triggered by one of the traces. For this purpose, the 556 allows the output of one sweep generator to be routed to the horizontal amplifier of the other beam, so it drives both beams. Many other more sophisticated modes are also available. | The 556 is a true dual-beam scope and none of the signal paths is shared between the two beams.
