S-6
The S6 sampling plug-in head is a 50 ohm feedthrough unit with a rise-time of 30ps and bandwidth of 11.5GHz. The S6 provides two unterminated 50-ohm SMA connections in a loop-through configuration. The S6 is specified for less than 5mV of noise. Note, that the unit provides no internal trigger pickoff signal for internal triggering! There is no internal termination, allways use a termination on the unit to give a minimum protection against electrostatic discharge at handling. It was introduced in 1971.
