The '''Tektronix Type 4S3''' is a 1 GHz dual-trace vertical [[sampling_oscilloscope|sampling]] plug-in | |||
for the [[661]] oscilloscope. It uses two [[P6038]] sampling probes. | |||
The probes contain sampling gates but not amplifiers. The front-end amplifier is in the 4S3 and is composed of a [[7308]] tube (premium 6DJ8) with its two triodes connected in a common-cathode cascode topology. | |||
