Description:
The Model 4015D Pulse Generator produces an ultra-fast pulse of -5 V with 12 ps falltime into 50 ohms. The pulse is generated in a small external pulse head that is attached to the main unit via a coaxial cable. This allows the pulse head to be directly connected where it is needed, eliminating the risetime slowing effects of interconnecting coaxial cables.
A -1.9 V, 22 ps impulse can also be generated with the 4015D by attaching the optional Model 5208 Impulse Forming Network to the pulse head output. If two 5208s are connected in cascade, a 1 V, 12.5 GHz monocycle will result. If higher power levels are required, the impulse or monocycle can be amplified by traveling wave tube amplifiers (TWTA).
