The Tektronix TM502A is a compact, 2-slot power module mainframe designed to house and power Tektronix TM500 series plug-in test and measurement instruments. It features a convection-cooled chassis and rear-panel series-pass transistors to dissipate heat outside of the individual instrument modules.
