Template:Plugin Sidebar 2 The Tektronix S-2 Sampling Head plug-in provides a single GR-874 50 Ω input with a 75 ps risetime.

The S-2 can be used in the 7000 series and 3S series of sampling plug-ins. It provides an internal trigger pickoff signal for internal triggering. Noise is specified as less than 10 mV.

When the S-2 was first introduced, the rise-time specification was 50 ps, but that was not achieved in practice, so the rise-time specification was revised to be 75 ps.

The interface between the GR-874 connector and the printed circuit board is described in US Patent 3,426,311.

Key Specifications

Rise time 75 ps
Bandwidth 4.66 GHz eq.
Input voltage -1 to +1 V (max. -5 to +5)
