S-6: Difference between revisions

Template:Plugin Sidebar 2 The Tektronix S-6 Sampling Head plug-in is a 50 Ω feed-through unit with a rise-time of 30 ps and bandwidth of 11.5 GHz. It was introduced in 1971. The S-6 provides two unterminated 50 Ω SMA connections in a loop-through configuration as is convenient for TDR applications.

It is good practice to leave a termination resistor on the unit when unused to give some protection against electrostatic discharge.

Key Specifications

Rise time	30 ps
Bandwidth	11.5 GHz

Measurements

Impulse taken with S6 sampling head. Every dot is equivalent to one sample taken, and combined on the CRT with a rate of app. 100 Hz. Bright dots are newer than dimmed ones.
Incident pulse from an S-52 (nom. < 25 ps) displayed by an S-6 head (nom. < 30 ps), both installed in a 7S12. Displayed rise time ~35 ps confirms spec.
