So I stumbeled over some "ancient" test equipment...

a HP 233A Audio Oscillator and a

HP175A 'scope with the
1780A AUX plug in (single or normal sweep, manual or external arming) and 1750A dual trace vertical amplifier plug in (dual trace and differential display, .05 v/cm to 20 v/cm sensitivity, 9 nsec rise time (DC to 40 mc bandwidth))

and a manual....

and a DEC H758-a power supply


what exactly would this type of stuff be used for? and can i kill myself tinkering around trying to learn to use it?
