The Tektronix S-50 is a pulse generator head the produces 400mV pulses with a risetime under 25ps. The pulse output is an SMA connector. The PRETRIG OUT and TRIG OUT signals use BSM connectors.
The output diode is the same one that the S-52 uses, the 153-0040-00. The internal timing circuitry of the S-50 uses two 152-0379-00 tunnel diodes.
The S-50 is similar to the S-52, but the output pulse amplitude of the S-50 is 400mV, twice that of the S-52. The S-50's output tunnel diode is directly connected to the main pulse output connector. The S-52 has a 48-ohm resistor between the output tunnel diode and the main pulse output connector, resulting in a 2:1 voltage divider.
