The S-1 sampling plug-in head provides a single GR-874 50 Ω input with a 350 ps rise-time.

The S-1 can be used with the 7000 series of sampling plug-ins, as well as the 3S series of sampling units.

Key Specifications

Rise time 350 ps
Bandwidth 1 GHz
Input amplitude -1 V to +1 V with ≤1 Vp-p signals
Maximum input ±5 VDC or sine of 10 Vp-p up to 10 MHz
Input impedance 50 Ω (GR-874)
Noise < 2 mV
Features trigger pickoff for internal triggering

Internals

The S-1 uses a two-diode sampling gate which has relatively high "kick-out" (leakage of the strobe signal out of the input). The manual cautions,

Operating the sampling head without the input connector terminated by a 50 Ω resistor or coaxial cable will cause a vertical shift of the zero signal baseline by a few millivolts. This is caused by the strobe kickout signal being reflected from the open input connector, and orriving bock at the sampling bridge while the bridge is conducting.
