The Tektronix Type 3S1 is a dual-trace [[sampling_oscilloscope|sampling]] plug-in for [[560-series scopes]]. The risetime is 350 ps. | |||
The many ways, the 3S1 is similar to the [[4S1]], but more compact. | In contrast to modular sampling plug-ins like the [[3S2]], the 3S1 has built-in sampling heads. The signal enters through [[Connectors#GR-874|GR-874 connectors]] on the front panel. Each channel has a resistive trigger pickoff followed by a 55 ns coaxial [[delay line]]. Following the delay line is a compensation circuit designed to (partially) undo the pulse degradation caused by the delay line, and also to provide proper termination for low return loss at the input. | ||
Next in the main signal path is a four-diode sampling bridge driven by a [[snap-off diode]], D73. | |||
In many ways, the 3S1 is similar to the [[4S1]], but more compact. | |||
The 3S1 provides +100VDC and -12.2VDC [[probe power]]. | The 3S1 provides +100VDC and -12.2VDC [[probe power]]. | ||
