Tektronix 1103
Probe power supply Tek 1103 Produced from 1989 to (?) Manuals 1101A, 1102, 1103 Manual 070-8276-02 1101A, 1102, 1103 Manual 071-2544-01 (S/N B040000+) 1103 Datasheet 60W-14843-1 (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
