Tektronix 1103
Probe power supply Tek 1103 Produced from 1989 to (?) Manuals Tektronix 1101A and 1102 and 1103 Manual (PDF) (All manuals in PDF format unless noted otherwise)

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 V_DC, 2.5 A supply, with switching regulators providing the four output voltages.

Power input	87 to 128 V_AC (low) or 174 to 250 V_AC (high), 48 to 440 Hz, ≤35 W
Power output	+15 V, −15 V, +5 V, −5 V ; ±2% each ; ≤300 mA each
Offset control	+1 to −1 V, course and fine control, 0 V when disabled
