The '''Tektronix 285''' is a power supply that allows S-50 series heads ([[S-50]]/[[S-52]]/[[S-54]] pulse generators or [[S-51]]/[[S-53]] trigger units) to be used as freestanding instruments instead of in an oscilloscope. The 285 provides regulated +15 V and -12.2 V to the pulse head. | |||
The trigger signal from the head's rear connector is brought out on a [[BSM connector]] on the 285's front. | |||
