It produces a 550 V negative-going pulse with 3.2 nanoseconds fall time. | It produces a 550 V negative-going pulse with 3.2 nanoseconds fall time. | ||
This fall time was confirmed experimentally by Dennis Tillman with an MP203 pulse output coupled to a [[7S11]] / [[7T11]] / [[S-4]] via 46 dB of attenuation (to reduce the pulse to 700 mV to protect the S-4). | This fall time was confirmed experimentally by Dennis Tillman with an MP203 pulse output coupled to a [[7S11]] / [[7T11]] / [[S-4]] via 46 dB of attenuation (to reduce the pulse to 700 mV to protect the S-4). | ||
