Pulse waveform examples

Typical pulse waveforms are shown in this section. Tektronix recommends using
a wide-band sampling oscilloscope to verify these waveforms. The oscilloscope
rise time must be less than 100 ps.

CAUTION.

The input circuitry of the oscilloscope can be damaged by directly

connecting the output of the pulse generator to the oscilloscope. To avoid
damaging the input circuitry of the oscilloscope, use attenuators to provide at least
46 dB attenuation between the output of the pulse generators and the oscilloscope.

The following

fi

gures show typical waveforms with the duration set to 5 ns. A

fi

xed 115 ns delay pulse is used to trigger the oscilloscope unless otherwise noted.

The displays are set to 10 V/div and 1 ns/div.
