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). | |||

Three pulse widths can be selected. | |||
The widest pulse is about 15 nanoseconds. | |||
The repetition rate is variable up to about 11.7 kHz. | |||
