The unit provides a trigger pickoff signal for internal triggering and is specified for less than 5mV of noise. The S4 is the fastest of the S-series plug-in samplers | ||
The S4 sampling gate is based upon a traveling wave trapped-charge transmission line in which the sampling window is set by the propagation time of pulse edge through a thick-film transmission line. This technique requires only a sharp pulse edge rather than a precise pulse width, which is harder to generate. | |||
The sampling diodes are housed in a special coaxial connector that provides a high bandwidth signal path. | The sampling diodes are housed in a special coaxial connector that provides a high bandwidth signal path. | ||
