067-1201-99
The Tektronix 067-1201-99 is a Power Module Tester and Utility Power Supply plug-in for the TM500 system.
It allows external measurement of the mainframe's pass transistors, AC and DC supplies for a plug-in slot.
It can also be used as a simple generic power supply delivering +5 V, 1 A (from the shared +12 V unregulated supply via a 7805 type regulator) and ±15 V, 400 mA with current limiting (the latter using the mainframe's pass transistors). For this mode, the rotary switch must be in position 3 and the toggle switch set to DC.
