1103
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 traditional LM317T and LM337T linear regulators with a mains-frequency transformer. A later model uses switching regulators fed from an external 12 VDC, 2.5 A supply.
