S-6: Difference between revisions

The S-6 is very similar to the [[S-4]] as that it uses a [[Sampler#Six-Diode_Sampler|6-diode traveling wave trapped-charge sampling gate]]. This gate is implemented in the [[155-0053-00]] hybrid. Since the S-6 is a feed-through sampling head, the blow-by compensation is implemented slightly differently using a 10 k resistor in the hybrid directly connected to the input signal. The S-6 replaces the discrete preamplifier of the [[S-4]] with two opamps from a [[155-0035-00]] quad opamp chip. The two other opamps are used to buffer the gate bias voltages.
