The Tektronix PG509 produces a fixed-amplitude rectangular positive pulse waveform.

The PG509 is intended for use as a stimulus for making measurements. It uses an avalanche transistor and charge line to generate the fast-rising output pulse.

For use in a TM500 / TM5000 series mainframe (mainframe required for use).

This is a test and working unit in nice overall condition.  Manual on CD included.
