It was specially designed to build a [[sampling oscilloscope]] configuration together with the [[7S11]] including one of the sampling heads. The fastest sweep is 10ps/div and lowest jitter is 10ps, depending on actual settings. | It was specially designed to build a [[sampling oscilloscope]] configuration together with the [[7S11]] including one of the sampling heads.
