The Agilent 215A is a versatile pulse generator which provides an output pulse with 1nanosecond rise and fall time. The maximum amplitude of the pulse output is 10 volts peak into a 50 ohm load or 20 volts peak into an open circuit. The 215A 50ohm output impedance minimizes reflection problems. The amplitude of the pulse may be varied with a calibrated 1 to 12 db attenuator. The pulse width is also variable, from 2 to 100 ns. Teh trigger pulse may be varied, from 10 ns after, to 140 ns before, the output pulse. Output pulses may be either positive or negative as controlled by a front panel switch. Trigger output pulses may be either positive or negative (also a front panel switch) with a rise time of 5 ns and amplitude of at least 1 volt into a 50 ohm load. An external trigger may be used to initiate pulses from the Model 215A or an internal repetition rate generator will provide pulses of a frequency from 100 cps to 1 MC. A manual control provides a single pulse out each time a button is pushed. A countdown feature allows the Model 215A to be synchronized with any trigger input signal up to 100 MC.
