The S-52 is similar to the [[S-50]], but the | |||
S-50 has twice the pulse amplitude. | |||
The reason for this is that the S-52 has a 48-ohm | |||
resistor between the output tunnel diode and the output connector, | |||
while the S-50 has no such resistor. Although the S-52 produces a smaller | |||
pulse, its output impedance is much better controlled than that of the S-50, | |||
and the output resistor may also provide some limited protection for the output | |||
tunnel diode. | |||
