25ps Push-Pull Pulse Generator
The 25 ps Push-Pull Pulse Generator produces simultaneous rising and falling edge pulses. One pulse generator head is a standard S-52, generating rising edge pulses. The other pulse generator head is a specially modified S-52 that produces negative edge pulses.
The 25 ps Push-Pull Pulse Generator (and its special negative pulse S-52) were for internal purposes, not for sale outside of Tektronix.
