S-50: Difference between revisions

Line 21:

The S-50 is similar to the [[S-52]], but the output pulse amplitude of the S-50 is 400 mV, 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.

The S-52 has a 48-ohm resistor between the output tunnel diode and the main pulse output connector,

Another difference between the S-50 and S-52 is the presence of a TRIG OUT on the front of the of S-50. Both have PRETRIGGER OUT connectors.
