If you get the "Sorry, the file cannot be displayed. There seems to be a technical issue ..." error when trying to view an image, a workaround is to click on the cog icon in the upper right side of the media viewer, and then select "Disable Media Viewer". We are aware of the problem and are looking for a solution.

The signal chain in sampling oscilloscopes contains a sampler, which measures the input signal at a moment in time.

Some sampling scopes, e.g., the 11201, have the sampler as an built-in component. Other sampling scopes have the sampler as a built-in component of the vertical plug-in, e.g., the 3S76.

Another setup is to have the sampler in a sampling head, e.g., the S-4. Sampling heads sometimes plug directly into the oscilloscope mainframe, e.g., in the 11801. In other cases, the sampling head plugs into a vertical plug-in, e.g., the 7S11, which plugs into the oscilloscope mainframe. Sampling heads can also be used on extension cables, e.g., the 012-0125-00, which allows the path between the device under test and the sampling head to be as short as possible for minimum signal degradation.

Tektronix sampling oscilloscopes use at least four different circuits: one-diode, two-diode, four-diode, and six-diode.

One-Diode Sampler

This is used in the Type N.

Two-Diode Sampler

This is used in the 1S2, early 4S2, 1502, S-1, S-2, and the 7S14.

Four-Diode Sampler

This is used in the 1S1, 3S1 and the 3S76.

Six-Diode Sampler

This is used in the S-4 and S-6.
