The Tektronix 1103 is a standalone probe power supply that enables probes with Tekprobe BNC connectors to be used with older equipment.
The original version uses a traditional linear power supply with a mains-frequency transformer and LM317T / LM337T regulators.
Later versions changed to an external 12 VDC, 2.5 A supply, with switching regulators providing the four output voltages.
