The S-4 was designed by George Frye and introduced in 1968. It is the fastest of the S-series plug-in samplers. (An interesting comparison of different sampling heads is found in "AN-3042a, Revision 1, 2/89".)

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.

Specifications

-The S-4 was designed by George Frye and [[introduced in 1968]]. The S4 sampling plug-in head provides one 50-ohm SMA input port with a 25ps risetime and a bandwidth of 14.5GHz. 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. A interesting comparison of different sampling heads is found in [http://www.picosecond.com/objects/AN-02a.pdf "AN-3042a, Revision 1, 2/89"].
