|Bandwidth : 1 GHz|
|Risetime 350 ps|
|50 ohms Input Impedance|
The S-1 Sampling Head is a low-noise, 350-ps risetime unit with a 50-Ω input impedance. It is designed for use with the 3S2, 3S5 and 3S6 Dual-Trace Sampling Units, 7S11 Sampling Unit, and 7S12 TDR Unit. The S-1 can be plugged in or attached by a cable for remote use. A trigger pickoff within the S-1 provides a trigger signal output from the plug-in unit.
350 ps or less.
Equivalent to DC to 1 GHz at 3-dB down.
Aberrations as observed with the 284 Pulse Generator are +0.5%, -3% or less, total of 3.5% or less P-P, first 5 ns following the step transition; +0.5%, -5% or less, total of 1% or less P-P after 5 ns.
2 mV or less, unsmoothed; 1 mV, smoothed.
Variable DC offset allows signals between +1 V and -1V limits to be displayed at 2 mV/div. Signals between +2 V and -2 V limits may be displayed at 200 mV/div. For best dot response with random-sampling sweep unit, signal amplitude should be less than 500 mV P-P.
Nominally 50Ω. Safe overload is 5V. GR874® input connectors.
